Explanation:

Double Circulatory System

The human circulatory system has three key components: blood vessels, blood and the heart. It is called a double circulatory system because blood passes through the heart twice per circuit.

The right pump sends deoxygenated blood to the lungs where it becomes oxygenated and returns back to the heart.

The left pump sends the newly oxygenated blood around the body. By the time this blood returns to the heart, it has returned to a deoxygenated state.
