Fantastic Voyage Battle of the Lung Essay Example for Free

Fantastic Voyage Battle of the Lung Essay Good morning everyone! Signing on, India Hornsby with ASAP Health. I will be reporting live inside Mrs. Frizzle. She has been under the weather for about two days now. A bacterium is invading the lower lobe of her right lung. It’s my job to pilot the invasion and do a live report on what I see. I will enter from the right femoral vein and follow a path to the lower lobe of the right lung via the right pulmonary artery. I will be describing the structures that I pass by and through. Once I have reached the lung, I will describe the structures that I see and discuss how the body fights against the invader. After that I will exit the body cross the alveolar membrane on a path and out the nose. I will enter Mrs. Frizzle body through the femoral vein. The femoral vein is located in the upper thigh and pelvic region of the body and runs close to the femoral artery (Yahoo Health, 2012). It’s one of the larger veins in the venal system (Yahoo Health, 2012). The femoral vein returns blood in the leg to the heart via the iliac vein (WiseGeek, 2012). Continuing North from the femoral vein I will pass through the inguinal ligament. The inguinal ligament forms a band that runs from the anterior superior iliac spine to the pubis area of the spine (Yahoo Health, 2012). It serves as a base to the inguinal canal because hernias can form there. The main function of the inguinal ligament is to protect the tissue that is constantly moving in the trunk and lower extremities of the body (Yahoo Health, 2012). From the inguinal ligament still heading north I will pass through the external iliac vein. The external iliac vein is a continuation of the femoral vein above the inguinal ligament. It starts at the groin and runs along the edge of the pelvic area (Yahoo Health, 2012). When it is combined with the internal iliac vein it forms the common iliac vein. The external iliac vein drains the leg and lower part of the anterior abdominal wall (Merriam-Webster, 2012). As I continue on I will pass the internal iliac vein to the East. The internal iliac vein combines with the external iliac vein to form the common iliac vein. It drains the pelvis, gluteal, and perineal regions (Merriam-Webster, 2012). Next I will be passing through the common iliac vein, which is formed by the external and internal iliac veins. It allows blood circulation from the lower abdomen and legs (Wise Geek, 2012). The hepatic vein carries deoxygenated blood out of the liver and into the inferior vena cava (Wise Geek, 2012). The blood that was used to feed the liver and the blood from the gastrointestinal tract, spleen, pancreas, and gallbladder is transported through the hepatic vein. From the hepatic vein I will then pass through the inferior vena cava. The inferior vena cava runs behind the abdominal cavity and alongside the right vertebra column of the spine (Yahoo Health, 2012). It carries oxygen depleted blood from the lower part of the body back to the heart. The inferior vena cava empties into the right atrium (Yahoo Health, 2012). Next stop is the right atrium. It’s located on the lower back side of the heart. The right atrium is one of the four chambers of the heart. Blood enters the heart through the two atriums (Yahoo Health, 2012). Oxygen depleted blood enters the right atrium via the inferior and superior vena cava (Yahoo Health, 2012). I will then pass through the tricuspid valve. It forms the boundary between the right ventricle and atrium (Yahoo Health, 2012). The tricuspid valve has tree flaps that keep blood from going back into the right atrium when they are closed. Next I will be moving on to the right ventricle. It is one of the four chambers of the heart, located at the lower left portion of the heart below the right atrium and opposite the left ventricle (Yahoo Health, 2012). The right ventricle is responsible for pumping oxygen depleted blood to the lungs. I will now pass through the right pulmonary artery. It begins at the base of the heart’s right ventricle and is approximately 3 cm in diameter and 5 cm in length (Yahoo Health, 2012). It then splits into the left and right pulmonary arteries. The right pulmonary artery delivers oxygen depleted blood to the right lung. From the right pulmonary artery I have made it to the right lung. Once in the lung I will travel South West to reach the lower lobe of the right lung. I’m finally in the lung. I can finally see what it looks like. I see a structure that looks like a three without leaves. I am passing the right primary bronchi. It is a tube like structure that allow for the passage of air between the trachea and lung (Health Type, 2012). As I move along the right primary bronchi branches off into the right secondary bronchi. Each one of the bronchi serves as an airway to a specific lobe of the lung (Wikipedia, 2011). The bronchi have cartilage plates, smooth muscles, and mucus-secreting gland cells in its wall (Wikipedia, 2011). They contain cilia, which removes dust and debris. Wow! The right secondary bronchi are branching off into very small passageways called bronchioles. The bronchioles are responsible for controlling air distribution and airflow resistance in the lungs (Wise Geek, 2012). They also contain cilia that help move air through the system. The bronchioles are now terminating at the alveolar ducts. They are the tiny end ducts that fill the lungs. At the end of the alveolar ducts are the alveolar sacs. The alveolar sacs resemble a cluster of grapes (Structure and Function, 2008). The walls of the alveolar sacs are made up of numerous alveoli, each of them resemble a single grape (Structure and Function, 2008). To fight the bacterium invasion in Mrs. Frizzle body a group of many organs and billions of freely-moving and trillions of free-floating molecules in different areas of the body work together (Structure and Function, 2008). Nonspecific or innate immunity is maintained by mechanisms that attack any irritant or abnormal substance that threatens the internal environment (Structure and Function, 2008). Mrs. Frizzle nonspecific immunity kicked in when the invading bacterium entered the lung. Pac man-like white blood cells called monocytes and macrophages take action. They then busily recruit a number of other cells including more macrophages, neutrophils, and natural killer cells (Greater Immunity, 2010). All these cells work together to defeat the invader. In the body’s defense, Mrs. Frizzle will develop a fever. The fever is the body’s way of dealing more effectively with the invader. Later, during recovery, lymphocytes become active and create antibodies which will help Mrs. Frizzle deal with that particular bacterium, if she happens to encounter it again (Greater Immunity, 2010). The activated lymphocytes and antibodies become part of Mrs. Frizzle acquired immunity. Specific or acquired immunity includes protective mechanisms that confer specific protection against certain types of invading bacteria or other toxic material (Structure and Function, 2008). Mrs. Frizzle built up specific immunity during her illness. Her memory cells in her immune system learned the illness and remembered how to beat it in the future if it was to occur again. Specific immunity can be natural or artificial. Natural immunity is naturally inherited from the parents. Artificial immunity is immunization. Now that the â€Å"Battle of the Lung† is documented I can return home. I will now cross the alveolar membrane into the alveoli. I will take the alveoli to the bronchioles. From the bronchioles I will pass through the bronchi. I will then take the bronchi to the trachea. Next I will take the trachea to the nasopharynx. Upon leaving the nasopharynx I will arrive at the orthopharynx. I will then take the orthopharynx to my destination, out the nose. This was indeed a fantastic voyage. I hope you have learned just as much as I have. Signing out, India Hornsby at ASAP Health.

Gilligan’s Perception of Morality in An American Story :: American Story Essays

Gilligan’s Perception of Morality in An American Story Though individuals live by and react similarly to various situations, not all people have the same morals. I can relate to instances where I have supported a belief, regardless of the criticisms that arise, all because my choice is based upon personal morals. The same can be said regarding Debra J. Dickerson as she expresses in her novel, An American Story. In Carol Gilligan’s â€Å"Concepts of Self and Morality,† she states, â€Å"The moral person is one who helps others; goodness in service, meeting one’s obligations and responsibilities to others, if possible without sacrificing oneself† (170). After considering this statement, I strongly feel that Gilligan’s proposal lacks the depth to accurately characterize the moral person, but I am able to accept the argument raised by Joan Didion. Her essay entitled, â€Å"On Morality,† clearly provides a more compelling and acceptable statement in describing the moral person by saying, â€Å"I fo llowed my own conscience, I did what I thought was right† (181). Joan Didion’s proposal is precise and acceptable. It is obvious that as long as people follow what they believe is the right thing to do, and approach the situation maturely, their actions can be considered examples of morality, and they can then be considered moral human beings. A moral person goes beyond the phrase, â€Å"without sacrificing oneself,† provided by Gilligan in her essay. This is clear by looking back at a specific example. I can recall a time when an entire class of mine decided to play a trick on a teacher in high school. They planned on manipulating her by telling lies in regard to what she had assigned and made her feel embarrassed. I wanted not to be part of these hurtful actions, so rather than tagging along as most of the other students, I did something about it. I stood my ground and as the students told one lie after another, I raised my hand and made her aware of the prank that was being executed. Though everyone looked upon me as the one who spoiled everything, the simple gesture of raising my hand revealed my morals to the class. At the time, I followed my conscience and followed through with what I thought was right, whether others agreed with me or not. This clearly supports and exemplifies Didon’s explanation o f the moral person.

Austronesian Migration Essay

Synopsis: Austronesia, in historical terms, refers to the homeland of the peoples who speak Austronesian languages, including Malay, Filipino, Indonesian, Maori, Malagasy, native Hawaiian, the Fijian language and around a thousand other languages. The Austronesian homeland is thought by linguists to have been prehistoric Taiwan. Review: Researchers believed that our Ancestors came from Southern China and traveled through Taiwan and arrive in Batanes, a northernmost province in the Philippines. They Inhabited the Area for over a Thousand Years. After a thousand years they travelled to south and arrived at Madagascar and also travelled east and arrived at Easter Island in South America. These travelers are called â€Å"Austronesian Speaking People† which means speakers from the South East Asian countries like Philippines, Indonesia, Malaysia and many more. Austronesian People are also Great Seafarers. They build and use Canoes for travelling the Open seas. They also developed the Technology to navigate and cross the Open seas. Historian’s believed that the Early Filipino’s used Outrigger canoes and sails for very large explorations. And they conclude that our Ancestors doesn’t cross land bridges from Brunei instead they used boats for Transportation. It is believed that Austronesians greatly contribute in the creation of different South East Asian languages an. These discoveries are proved by Relics and Artifacts found in the Colonized countries. Like Burial Jars ( Manunggul Jar ), Talismans, Jewelries ( Lingling-o ) and Tools/Ornaments. Since the Ancient times, Trades are present in the Philippines. Our Ancestors are trading Ornaments and goods for Minerals, Porcelain items, Jewelries, Accessories etc. This proves that our Ancestors played an important role in the Growth of the  Culture and Languages in the whole world.

Humbug Definition

Humbug was a word used the 19th century to mean a trick played upon unsuspecting people. The word lives on in the English language today thanks largely to two notable figures, Charles Dickens and Phineas T. Barnum. Dickens famously made â€Å"Bah, humbug!† the trademark phrase of an unforgettable character, Ebenezer Scrooge. And the great showman Barnum took delight in being known as the â€Å"Prince of Humbugs.† Barnum’s fondness for the word indicates an important characteristic of humbug. It isn’t just that a humbug is something false or deceptive, it is also, in its purest form, highly entertaining. The numerous hoaxes and exaggerations which Barnum exhibited during his long career were termed humbugs but calling them that indicated a sense of playfulness. Origin of Humbug as a Word The word humbug seems to have been coined sometime in the 1700s. Its roots are obscure, but it caught on as slang among students. The word began appearing in dictionaries, such as in the 1798 edition of A Dictionary of the Vulgar Tongue edited by Francis Grose: To Hum, or Humbug. To deceive, to impose on one by some story or device. A humbug; a jocular imposition, or deception. When Noah Webster published his landmark dictionary in 1828, humbug was again defined as an imposition. Humbug as Used by Barnum The popular use of the word in America was largely due to Phineas T. Barnum. Early in his career, when he exhibited obvious frauds such as Joice Heth, a woman said to be 161 years old, he was denounced for perpetrating humbugs. Barnum essentially adopted the term and defiantly chose to consider it a term of affection. He began to call some of his own attractions humbugs, and the public took it as good-natured kidding. It should be noted that Barnum despised people like con men or snake oil salesmen who actively cheated the public. He eventually wrote a book titled The Humbugs of the World which criticized them. But in his own usage of the term, a humbug was a playful hoax that was highly entertaining. And the public seemed to agree, returning time and again to view whatever humbug Barnum might be exhibiting. Humbug as Used by Dickens In the classic novella, ​A Christmas Carol by Charles Dickens, the miserly character Ebenezer Scrooge uttered â€Å"Bah, humbug!† when reminded of Christmas. To Scrooge, the word meant a folly, something too silly for him to spend time on. In the course of the story, however, Scrooge receives visits from the ghosts of Christmas, learns the true meaning of the holiday, and ceases to regard celebrations of Christmas as humbug.
