Mesenteries: thin, transparent sheets of connective tissue containing blood vessels connecting the intestine and other organs. The mesenteries are folds of the peritoneum, which is the smooth, shiny layer that lines the abdominal cavity. Pancreas: white and looks a little bit like cauliflower. It secretes digestive enzymes and buffers. Abdominal cavity: other organs Locate and understand the functions of the following structures: Kidneys. The two kidneys are not actually located in the abdominal cavity; they occupy another coelomic compartment dorsal to the abdominal cavity. They are outside of the peritoneum. You won't see them until you move the intestines aside. Urine from the kidneys goes into the urinary bladder, and then through the urethra as it is eliminated from the body. You can also dissect the kidneys themselves; see the page on kidneys at Whitman College for more information.

The spleen is a flat organ located near the stomach. It performs several functions related to producing and maturing new blood cells and eliminating old ones. Blood passes through open sinuses in the spleen, rather than being confined to narrow blood vessels. The urethra is the tube that carries urine from the urinary bladder to the urinary opening.

The testes of males and the ovaries of females both arise from the same embryonic structures; however, the testes migrate during fetal development until they descend into the scrotal sac. Circulatory system Mammalian hearts have four chambers see Campbell, p. Each side of the heart has an atrium that receives blood from elsewhere in the body and a ventricle that pumps the blood out of the heart. The right atrium receives blood from the systemic circulation and passes it to the right ventricle, which pumps the blood to the pulmonary circuit.

The Ultimate Fetal Pig Dissection Review
After the blood passes through the lungs it goes to the left atrium and then into the left ventricle, which pumps the blood into the systemic circuit. The first part of the systemic arterial circuit is the aorta, which soon branches out to supply various regions of the body. Fetal circulation is different from adult circulation. The umbilical arteries carry blood from the fetus to the placenta. The umbilical vein carries blood from the placenta back to the fetus. Remember that in the placenta substances are exchanged between fetal and maternal blood, but the blood itself does not mix. Therefore, the most highly oxygenated blood in the fetus is in the umbilical vein. Blood from the umbilical vein gets mixed with the rest of the systemic circulation and returns to the right atrium. The fetus has two key tricks to adapt to this fact: First, some of the blood that leaves the right ventricle bypasses the lungs.

In an adult, this blood needs to go to the lungs to get oxygenated, but the fetus has a ductus arteriosus that short-circuits this blood flow, allowing some blood to go directly into the aorta and then into the systemic circulation. Second, in the fetal heart, there is an opening between the right atrium and the left atrium. This opening is called the foramen ovale. The foramen ovale is helpful in the fetus because it lets the oxygenated blood from the placenta get circulated faster. The circulation pattern is somewhat similar to that of a frog Campbell, p. The foramen ovale normally closes up at birth, keeping blood flow of the two sides of the heart completely separate.

Look for these features: Males: Urogenital opening is located near the umbilicus; the penis is hidden inside. The scrotal sac may be visible as a swelling just ventral to the anus, depending on the age of the fetus.
