Blood passes from the left ventricle through the aortic arch and aorta to the body. Fetal pigs not used in classroom dissections are often used in fertilizer or simply discarded. As a result, a structure shown in one photograph may look different than the same structure shown in another photograph. Urinary System Anatomy. Large intestine, liver, small intestine, spleen, and stomach. You have already seen the pharynx, hard palate, soft palate, epiglottis, glottis, trachea, and larynx. The first branch of the aorta is the brachiocephalic artery. Data from a study in 1976 by Nelson and Robinson showed that gilts from a small litter size ovulated more than the gilts from the larger litters. Shared traits include common hair, mammary glands, live birth, similar organ systems, metabolic levels, and basic body form. The anatomy of a fetal pig is similar to that of the adult pig in various aspects. Dissected, narrated and labeled by Dr. Robyn Nearn, DVM. Using a probe, trace follow the esophagus to the stomach. The amount of floor space has been shown to impact the time it takes gilts to reach puberty. However, there is a correlation between a mother pig having a nutritious diet containing proteins, vitamins and minerals during gestation period and the survival rate of piglets. Pig lab 2 - lab notes. Urinary System Anatomy. Anatomy of the Male Reproductive System. This diagram shows that the ductus arteriosus connects the pulmonary artery to the aorta and diverts blood that would otherwise go to the lungs. The path that urine takes to exit the body is very specific. It contains a lubricating fluid and isolates the heart from body movements such as the expansion and contraction of the nearby pleural (lung) cavity.

Here we show the single kidney opened/bissected along its long axis into two halves (we cut from the lateral margin -- the ureter is still intact and connected to the renal pelvis). This diagram shows that the ductus arteriosus connects the pulmonary artery to the aorta and diverts blood that would otherwise go to the lungs. The right subclavian carries blood to the right front leg and the carotids carry blood to the head. After food is digested and nutrients are absorbed, the food follows through the large intestine and solid wastes are excreted through the anus. The liver has been lifted to reveal the gallbladder. The purpose of the experiment was to understand how strong a bessbug by using weights and observing the time the best bug takes to travel to a certain distance.

Your finished cut will be anterior to the navel and along each side of the navel. Along with frogs and earthworms, fetal pigs are among the most common animals used in classroom dissection. In this particular dissection a fetal pig was used because the organs present in a pig, and their position in the body are similar to those of humans which provides insight on how human organs systems work overall and why they are essential to life. The size of the fetal pig depends on the time allowed for the mother to gestate: No studies have found significant data regarding the mother swines diet and fetal pig survival rate. PDF.
