3. Describe the structure and function of each of the three layers of the heart wall.…
The purpose of this experiment was to identify the internal and external organs of the fetal pig.…
The purpose of dissecting the fetal pig is to experience way the body looks internally. The fetal pig body organs are similar to the organs in a human body as well as the functions.…
Given the information presented in the lecture and chapter 13, label a diagram of the heart.…
When snow white's hunter used a pig heart to fool the evil queen, he was not totally in the wrong. Pig hearts and human hearts and very similar in structure and function. Pig Valves, however, should not be used in patients. Even though the pig valve heart transplant has been around for over 30 years, it's cons outweigh it's pros. The process of preparation eventually add to the downfall of the method. Pig valves are trimmed then fixed in buffered glutaraldehyde at high pressure. A pig heart valve is comprised of three main components: collagen, elastin, and glycosamino¬glycans (GAGs). Collagen fibers provide strength to the overall structure while elastin molecules give the valve elasticity. Finally, GAGs act as a cushion between the collagen and elastin layers. Glutaraldehyde has been shown to sterilize the tissue and prevent inflammation. The problem is, glutaraldehyde causes faster deterioration of pig valves. Again, pig valves should not be used in transplants.…
Name the 3 muscle layers of the heart, give an example of where you would find these:…
5. The thymus in the fetal pig is large because it is a fetus. As the pig matures, the thymus will shrink.…
1. How does the heart change as it develops in a fetus? At first, the heart is just a tube. It grows so fast that it needs more space, so it bends and twists back, forming the familiar shape. During the next phase, the two atria are partly separate but there is just one big ventricle. The next phase begins when the two atria are completely separate and the ventricles are just beginning to separate. Finally, the ventricles separate completely and the heart is developed.…
The ventricles are much bigger than the atria and the left ventricle is bigger than the right ventricle.…
In the figure fourth is the fetal pig incisions. The picture show many different part in the pig that we need to know to really understand what we going to do before starting doing our experiment .We need to know each part where there are and their functions so when we start open our pigs that we do not mess it at all.…
Choose the correct answer for each question and mark it on your bubble sheet. Be careful to follow the instructions on the bubble sheet for correctly recording your answers.…
2. Discuss the anatomical differences between frog and human hearts. The frog heart has a single ventricle and two atria.…
The heart was a light pink color and was shaped like an acorn (see figure 7). The heart was located ventral to the lungs and in the medial part of the thoracic cavity. An incision was made on the heart in the mid sagittal plane. The heart was transected into two pieces. The four chambers of the heart could be…
The purpose is to identify and know the major anatomical and physiological features of the dissected fetal pig. Another purpose is to comprehend the relationship between structure and function in the body and relate concepts to the structures found in the fetal pig. We must recognize how the different systems in the body work together and develop so the body maintains in homeostasis.…
On the first day of the lab I observed the pig's digestive system which includes the liver,small intestines, large intestine, and the pancreas. The liver was the largest organ in the fetal pig's body and was shaped like small bean bag. I was actually surprised when seeing the small intestine because I didn't know it was bigger than the large intestine, it was a series of long brown tubes. The pancreas of a fetal pig is along the bottom of the stomach. The pancreas is a bumpy yellowish brown gland.…
