Final answer:
The right side of the heart receives blood from the body and pumps it through the pulmonary circuit to the lungs, where it is oxygenated. The oxygenated blood then returns to the left side of the heart and is pumped to the rest of the body through the systemic circuit.
Step-by-step explanation:
The right side of the heart receives blood from the body and pumps it through the pulmonary circuit to the lungs.
In the pulmonary circuit, deoxygenated blood is pumped from the right side of the heart to the lungs, where it is oxygenated. The oxygenated blood then returns to the left side of the heart and is pumped to the rest of the body through the systemic circuit.
