In future experiments it would be better to have a smaller pig so that the incisions are much cleaner and easier to perform. Largest artery in circulatory system. Yes, there is difference in the sizes of both lungs; the right lung is larger than the left due to the fact that the heart is mostly on the left side of the lungs.
The gall bladder is a small sac behind the liver that stores the bile made in the liver. It also decomposes left over material through micro-organisms and bacteria. The reason as to why the left ventricle contains more muscle than the right ventricle is because the left ventricle must be strong Pig dissection lab report to pump the blood throughout the body while the right ventricle only needs to pump the blood to the nearby lungs.
The heart is found between the two lungs and protected by rib cage. Transports deoxygenated blood to lungs. Remove stomach by cuts at junction with esophagus and small intestine, specifically, the duodenum. This can be done so using a scalpel. Also, it was positioned; front feet curled inwards and back feet are flat normal pos.
This could be due to the amount of time the pig was preserved for. The liver is the largest organ in the body and produces many enzymes and bile, which is stored in the gall bladder and contains bile salts that break down fat globules. The jejunum and the ileum both are the sites of absorption and are lined with villi and microvilli, which increase the surface area in and can absorb the nutrients digested by the duodenum.
The entire pig was one beige colour. It is a finger-shaped gland, and creamy white in colour. The hormone cholecystokinin from the small intestine signals the gall bladder to release the bile into the duodenum to digest fats. Two blood vessels were seen within the umbilical cord. Although the pig fetus was larger than what was expected, the procedure went well and all the necessary parts of the pig were visible.
Lungs are relatively large due to the fact that the bronchial tree is contained within them. This experiment allowed biology students to learn, in a hands-on way, about the many systems of the body. The right ventricle must pump blood to the pulmonary artery, which the pulmonary artery then transports blood to the lungs to oxygenate them.
The lungs feel spongy because there are millions of alveoli in the lungs. May use scissors for lateral incision. When locating small and large intestines, observe the thing film that holds them together.
Some of the livers other functions include detoxifying poisonous chemical substances such as caffeine and alcohol, and stores glycogen, vitamin A, B12, D and fats. Finally, remove heart from thoracic cavity by teasing away connective tissue.
For example, when one is injured and has a cut, the spleen will supply it with blood. The stomach stores about 1 — 2 L of food for about 4 hours. The spleen is located on left side of fetal pig, found near outer curvature of stomach.
Cut towards lateral surface. The left ventricle contains more muscle than the right ventricle because the left ventricle must pump blood to the aorta, which the aorta then transports blood to the entire body. Place fetal pig on back, exposing the dorsal surface.
Sex of pig can easily be determined through viewing posterior view of pig. Analysis What is the function of the umbilical cord? Vital substances the pancreas provides us with is insulin. Because there are little spaces between the alveoli, they do not make a solid feeling organ, they make a spongy feeling one.
Locate liver and gall bladder.
The cartilaginous rings of the trachea keep the trachea open for air to enter the lungs with oxygen and leave with carbon dioxide. Cut towards posterior portion of abdominal cavity. Thoracic cavity is area between incisions 3 and 5.Introduction Fetal Pig Dissection Report The fetal pig is used in the study of human anatomy because they are structurally similar to that of a human specimen.
The dissection of a fetal pig is useful in understanding the composition of the human brain. Mammalian brains are very similar in structure. Fetal Pig Dissection: Lab Report Friday, December 06, Saadaf Mohsin Gurjot Randhawa Manvir Benipal Mrs. J.

Essays - largest database of quality sample essays and research papers on Fetal Pig Dissection Lab Report. Fetal Pig Dissection Lab Answers Introduction Pigs, one of the most similar animals to humans, have been used to inform and teach students about the circulatory, respiratory, and digestive system through a procedure called a dissection for many years.
Welcome to the Whitman College Biology Department's Virtual Pig Dissection (VPD)! This site is designed as a supplement to laboratory dissections exploring introductory mammalian anatomy and physiology — it is basic and many details have been omitted for clarity.
We hope that it is suitable for AP.Download
