Description

Fetal Pig Dissection Activities #2 and #3 Lab Journal Type Name: Jazlyn Lundy 1. Is your fetal pig specimen male or female? What are the key characteristics to determine the sex of the pig? (2 pts) a. My pig was a female. The urogenital opening was near the anus. 2. Take a photo(s) of the pelvic cavity. Upload the photo(s) here and then label a minimum of five reproductive or urinary structures using text boxes and arrows. Then list the function of each organ underneath the photo. (5 pts)

Bladder Kidney

Umbilical cord

Urethra Rectum

Kidney- make urine

Urethra- allows urine to pass outside the body Bladder- urine storage Rectum- temporary storage for feces Umbilical cord- connects the fetus to placenta 3. Take a photo(s) of the thoracic cavity. Upload the photo and then label a minimum of five structures in the photo using text boxes and arrows. Then describe function of each organ underneath the photo. (5 pts) a. Heart- pumps blood through the body b. Lung- move air into the body and remove waste gases c.

4. Discuss how the

Heart Lung

structure of the pig heart is similar to a human heart. Describe the organization of the chambers and the valves. (3 pts) a. Pig’s hearts also have four chambers, like the human heart. It consists of two atriums and two ventricles, four valves, and an aorta.

5. Thinking about the circulatory system, describe the pathway of blood flow through the pulmonary and systemic circuits (start and end at the right atrium). (5 pts) a. The right atrium and ventricle transfer deoxygenated blood to the lungs through the pulmonary arteries. Blood is then reoxygenated and returned to the left atrium through the pulmonary veins. The left ventricle pumps the oxygenated blood to the body through the aorta. It then flows through arteries, arterioles, then capillaries where gas exchange occurs. Blood is then returned to the heart through the superior and inferior vena cava and empties back into the right atrium. 6. Describe where urine is made, where it is stored, and how it exits the body. (3 pts) a. Urine is collected from the nephrons and flows into the ureters of the kidneys. It is stored in the bladder, and then exits the body through the urethra. 7. Upload a photo that shows you doing the dissection activity. (2 pts)...
