Verified step by step guidance

Begin by understanding the basic structure of the heart, which consists of four chambers: the right atrium, right ventricle, left atrium, and left ventricle.

Recognize that blood flow through the heart is a cycle that involves two main circuits: the pulmonary circuit and the systemic circuit.

In the pulmonary circuit, deoxygenated blood flows from the right atrium to the right ventricle, and then it is pumped to the lungs via the pulmonary arteries for oxygenation.

After receiving oxygen in the lungs, the blood returns to the heart, entering the left atrium, and then flows into the left ventricle.

In the systemic circuit, the oxygenated blood is pumped from the left ventricle to the rest of the body through the aorta, delivering oxygen and nutrients to tissues before returning to the right atrium, completing the cycle.
