How is a fetal pig and sheep heart similar?
If you look at the back wall of a fetal pig heart, you will see a vessel that is large in size in a sheep compared to the small size of the fetal pig heart. In sheep, the hemiazygous vein develops a connection to the heart through what becomes the superior vena cava.
What are oncofetal antigens?
proteins made by genes that are very active during fetal development but function at a very low level after birth. The genes become activated when a malignant tumor arises and produce large amounts of protein
Describe fetal congenital cystic adenomatoid malformation?
A condition in which one or more lobes of the lungs become fluid-filled sacs (cysts). Large CCAMs may prevent lung development, cause heart failure, or prevent the ingestion of amniotic fluid.
Why does a fetal pig have a large liver?
The function of the liver is the remove toxins and metabolic wastes from the body. Fetal pigs have large livers because this function is important early on in life.
What is another name for the large intestine in a fetal pig?
Colon
Artrial ligament connects pulmonary trunk to arch of aorta but pulmonary contains deoxygenated blood where as aorta contains oxygenated how ever in fetal life it by pass lungs how?
The arterial ligament in adults was once the arterial duct (ductus arteriosus) in the fetus. This is a connection between the pulmonary trunk, the large vessel leaving the right side of the heart that in an adult would be conducting deoxygenated blood to the lungs for some oxygen, and the aorta, the large vessel leaving the heart with the oxygenated blood for the rest of the body. Along with the ductus venosus, moving oxygenated blood from the mother/placenta directly to the large vein feeding the heart, and the foramen ovale connecting the two atria inside the heart, fetal blood flow from the heart mostly bypasses the lungs and goes right into general circulation. The primary reason for this is that the lungs are not being used to collect oxygen from the environment, as the placenta is exchanging oxygen from the mother's blood to the fetal blood.
What gland found in the upper thorax overlying the heart and large during youth?
The thymus gland is in the upper thorax anterior to the heart.
What is the weight of fetal pig intestines?
The weight of a fetal pig's small intestine is said to be about 8.13 g. The weight of its large intestine is said to be 3.03 g.
The development of agriculture in California during the late nineteenth century was characterized by?
In the late 19th century, the development of agriculture in California was characterized by large-scale farming. A large amount of migratory workers was another characteristic.
What is found in the upper thorax overlying the heart also large during youth?
Thymus gland
Is the liver of a fetal pig active?
Fetal pigs are relatively large with well-developed organs that are easily visible. As long as the pork industry exists, fetal pigs will be relatively abundant, making them the prime choice for classroom dissections. The development of the lymphatic system and the formation of blood circulation occur at different stages of fetal pig development. The first lymphatic organ to become present is the thymus. Lymphocyte builds up in the spleen on the 70th day. By day 77, the thymus is already completely developed and is distinguishable from other organs. Also, follicles are present on the tongue and intestines on day 77. On the 84th day, periarteriolar lymphoid sheaths appear in the fetal pig. By this time, the liver and bone marrow are active and functional.
Function of large intestine in fetal pig?
The small intestine functions in digestion, and the large intestine functions in reabsorbing water and ions.
