What is the purpose of the fetal pig lab dissection?

How does blood flow in a fetal pig?
Pigs like other mammals have a four-chambered heart. The right side of the heart pumps blood to the lungs (pulmonary circulation), and the left side pumps blood out to the rest of the body (systemic circulation). After oxygenation, the blood travels back to heart via the pulmonary veins and enters the left atrium.
