Good forenoon everyone! Signing on. India Hornsby with ASAP Health. I will be describing unrecorded inside Mrs. Frizzle. She has been under the conditions for approximately two yearss now. A bacteria is occupying the lower lobe of her right lung. It’s my occupation to fly the invasion and make a unrecorded study on what I see. I will come in from the right femoral vena and follow a way to the lower lobe of the right lung via the right pneumonic arteria. I will be depicting the constructions that I pass by and through. Once I have reached the lung. I will depict the constructions that I see and discourse how the organic structure battles against the encroacher.
After that I will go out the organic structure cross the alveolar membrane on a way and out the nose. I will come in Mrs. Frizzle organic structure through the femoral vena. The femoral vena is located in the upper thigh and pelvic part of the organic structure and runs near to the femoral arteria ( Yahoo Health. 2012 ) . It’s one of the larger venas in the corruptible system ( Yahoo Health. 2012 ) . The femoral vena returns blood in the leg to the bosom via the iliac vena ( WiseGeek. 2012 ) . Continuing North from the femoral vena I will go through through the inguinal ligament.
The inguinal ligament forms a set that runs from the anterior superior iliac spinal column to the pubis country of the spinal column ( Yahoo Health. 2012 ) . It serves as a base to the inguinal canal because hernias can organize at that place. The chief map of the inguinal ligament is to protect the tissue that is invariably traveling in the bole and lower appendages of the organic structure ( Yahoo Health. 2012 ) . From the inguinal ligament still heading north I will go through through the external iliac vena. The external iliac vena is a continuance of the femoral vena above the inguinal ligament.
It starts at the inguen and runs along the border of the pelvic country ( Yahoo Health. 2012 ) . When it is combined with the internal iliac vena it forms the common iliac vena. The external iliac vena drains the leg and lower portion of the anterior abdominal wall ( Merriam-Webster. 2012 ) . As I continue on I will go through the internal iliac vena to the East. The internal iliac vena combines with the external iliac vena to organize the common iliac vena. It drains the pelvic girdle. gluteal. and perineal parts ( Merriam-Webster. 2012 ) .
Following I will be go throughing through the common iliac vena. which is formed by the external and internal iliac venas. It allows blood circulation from the lower venters and legs ( Wise Geek. 2012 ) . The hepatic vena carries deoxygenated blood out of the liver and into the inferior vein cava ( Wise Geek. 2012 ) . The blood that was used to feed the liver and the blood from the GI piece of land. lien. pancreas. and gall bladder is transported through the hepatic vena. From the hepatic vena I will so go through through the inferior vein cava.
The inferior vein cava runs behind the abdominal pit and alongside the right vertebra column of the spinal column ( Yahoo Health. 2012 ) . It carries O depleted blood from the lower portion of the organic structure back to the bosom. The inferior vein cava empties into the right atrium ( Yahoo Health. 2012 ) . Following halt is the right atrium. It’s located on the lower back side of the bosom. The right atrium is one of the four Chamberss of the bosom. Blood enters the bosom through the two atriums ( Yahoo Health. 2012 ) . Oxygen depleted blood enters the right atrium via the inferior and superior vein cava ( Yahoo Health. 2012 ) .
I will so go through 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 traveling back into the right atrium when they are closed. Following I will be traveling on to the right ventricle. It is one of the four Chamberss of the bosom. located at the lower left part of the bosom below the right atrium and opposite the left ventricle ( Yahoo Health. 2012 ) . The right ventricle is responsible for pumping O depleted blood to the lungs. I will now go through through the right pneumonic arteria.
It begins at the base of the heart’s right ventricle and is about 3 centimeters in diameter and 5 centimeter in length ( Yahoo Health. 2012 ) . It so splits into the left and right pneumonic arterias. The right pneumonic arteria delivers oxygen depleted blood to the right lung. From the right pneumonic arteria I have made it to the right lung. Once in the lung I will go South West to make the lower lobe of the right lung. I’m eventually in the lung. I can eventually see what it looks like. I see a construction that looks like a three without foliages. I am go throughing the right primary bronchial tubes.
It is a tubing like construction that allow for the transition of air between the windpipe and lung ( Health Type. 2012 ) . As I move along the right primary bronchial tubes branches off into the right secondary bronchial tube. Each one of the bronchial tube serves as an air passage to a specific lobe of the lung ( Wikipedia. 2011 ) . The bronchial tube have gristle home bases. smooth musculuss. and mucus-secreting secretory organ cells in its wall ( Wikipedia. 2011 ) . They contain cilia. which removes dust and dust. Wow! The right secondary bronchial tubes are ramifying off into really little passageways called bronchioles.
The bronchioles are responsible for commanding air distribution and airflow opposition in the lungs ( Wise Geek. 2012 ) . They besides contain cilia that help travel air through the system. The bronchioles are now ending at the alveolar canals. They are the bantam terminal ducts that fill the lungs. At the terminal of the alveolar canals are the alveolar pouch. The alveolar pouch resemble a bunch of grapes ( Structure and Function. 2008 ) . The walls of the alveolar pouch are made up of legion air sacs. each of them resemble a individual grape ( Structure and Function. 2008 ) .
To contend the bacteria invasion in Mrs. Frizzle organic structure a group of many variety meats and one million millions of freely-moving and millions of free-floating molecules in different countries of the organic structure work together ( Structure and Function. 2008 ) . Nonspecific or unconditioned unsusceptibility is maintained by mechanisms that attack any thorn or unnatural substance that threatens the internal environment ( Structure and Function. 2008 ) . Mrs. Frizzle nonspecific unsusceptibility kicked in when the invading bacteria entered the lung. Pac man-like white blood cells called monocytes and macrophages take action.
They so busily enroll a figure of other cells including more macrophages. neutrophils. and natural slayer cells ( Greater Immunity. 2010 ) . All these cells work together to get the better of the encroacher. In the body’s defence. Mrs. Frizzle will develop a febrility. The febrility is the body’s manner of covering more efficaciously with the encroacher. Later. during recovery. lymphocytes become active and create antibodies which will assist Mrs. Frizzle trade with that peculiar bacteria. if she happens to meet it once more ( Greater Immunity. 2010 ) . The activated lymph cells and antibodies become portion of Mrs.
Frizzle acquired unsusceptibility. Specific or acquired unsusceptibility includes protective mechanisms that confer specific protection against certain types of occupying bacteriums or other toxic stuff ( Structure and Function. 2008 ) . Mrs. Frizzle built up specific unsusceptibility during her unwellness. Her memory cells in her immune system learned the unwellness and remembered how to crush it in the hereafter if it was to happen once more. Specific unsusceptibility can be natural or unreal. Natural unsusceptibility is of course inherited from the parents. Artificial unsusceptibility is immunisation.
Now that the “Battle of the Lung” is documented I can return place. I will now traverse the alveolar membrane into the air sac. I will take the air sac to the bronchioles. From the bronchioles I will go through through the bronchial tube. I will so take the bronchial tube to the windpipe. Following I will take the windpipe to the nasopharynx. Upon go forthing the nasopharynx I will get at the orthopharynx. I will so take the orthopharynx to my finish. out the olfactory organ. This was so a antic ocean trip. I hope you have learned merely every bit much as I have. Signing out. India Hornsby at ASAP Health.
