Answered by QHM

Explanation:

➡️The human heart is sometimes called a double pump because it drives blood along two separate pathways in the circulatory system. With each beat, the heart drives arterial blood through the body, and it draws venous blood back toward itself.

➡️The high-pressure loop of the system is arterial. Blood is pushed through this system when the left ventricle contracts to squeeze fresh, oxygenated blood through the aorta.

From there, the blood flows throughout the body to deliver oxygen and essential nutrients to most of the body's cells.

➡️With the same ventricular contraction, the smaller right ventricle drives blood through the low-pressure system of deoxygenated blood.
