Remove the digestive organs to study the excretory and reproductive organs that make up the urogenital system.

Locate the large, bean-shaped kidneys lying against the dorsal body wall. Notice that they are covered by the peritoneum. Kidneys filter wastes from the blood. 

Find the ureters, tubes which extend from the kidneys to the bag-like urinary bladder. The urinary bladder lies between the umbilical arteries and temporarily stores liquid wastes filtered from the blood. 

Lift the urinary bladder to find the urethra, the tube which carries urine out of the body. Follow the urethra to the urogenital opening on the outside of the pig’s body.

Make sure that incision # 6 extends all the way to the anus but be careful to not cut too deep and damage the internal organs.

In the female pig, find the two bean-shaped ovaries at the posterior end of the abdominal cavity. Observe the coiled Fallopian tube attached to each ovary, which carries eggs from the ovary.

Follow the Fallopian tube to the uterus. The uterus is dorsal to the urinary bladder and the urethra.

Trace the uterus to a muscular tube called the vagina. The vagina will appear as a continuation of the uterus. Sperm from the male are deposited into this organ during mating. The vagina and the urethra open into a common area called the urogenital sinus. This cavity opens to the outside at the urogenital opening.
