What is a rostrum of a fetal pig?
the rostrum is the snout of a fetal pig
What is the function of the epididymis of the fetal pig?
The epididymis in a fetal pig is responsible for producing sperm. It is located on one testicle in the fetal pig.
How long can a fetal pig live?
A fetal pig is an unborn pig used in schools for dissection. Therefore, a fetal pig doesn't have a life span, because they never actually lived.
What part of the fetal pig stores bile and lies underneath the fetal pig?
gullbladder
Why would you not expect to find food in the stomach of the fetal pig?
There is a very good reason there is no food found in a fetal pig's stomach. The fetal pig was never born.
Why is circulation to the lungs bypassed in fetal pigs?
It is bypassed because there is no need for the blood to go to the lungs and get "pick up" if the pig is dead.
What keeps the trachea from collapsing in the fetal pig?
The uterus keeps the trachea from collapsing in a fetal pig.
What is the lower trunk area on a fetal pig called?
The lower trunk area on a fetal pig is called the posterior region of the pig.
What are the major arteries and veins found around a fetal pig heart?
the pulmonary artery, coronary arteries and veins, inferior vena cava, branch arteries, and superior vena cava
What is the function of a sensory papillae in a fetal pig?
The sensory papillae are located in the chest cavity of the fetal pig. These papillae are important for respiration of the pig.
What does Fetal Pig mean?
Fetal, as in fetus. Same as othermammals.
What happens in fetal pig circulation?
There are three major differences between normal circulatory pathways and fetal circulation. First, as you have already learned, oxygenated blood that is high in nutrients obtained from the placenta enters the fetal pig body not from lung capillaries, but via the umbilical vein to the ductus venosus in the liver. The ductus venosus leads in turn to the caudal vena cava, through which the blood enters the right atrium. The second major difference is the presence in fetal pigs of an opening between the heart atria (through the interatrial septum), called the foramen ovale. Oxygenated blood entering the right atrium from the caudal vena cava tends to pass through the foramen ovale into the left atrium, thus bypassing the pulmonary circulation system. Deoxygenated blood from the cranial vena cava enters the atrium anteriorly and flows into the right ventricle. As a result of this arrangement, there is little mixing of oxygenated and deoxygenated blood. A third major difference is the action of the ductus arteriosus vessel, which shunts blood away from the fetal pig's lungs and into the aorta. Highly oxygenated blood in the left atrium is pumped into the left ventricle and then into the aorta. It then enters the coronary arteries and the arteries of the head region, before mixing with deoxygenated blood from the ductus arteriosus and the lower systemic circulation.
