The human heart is a muscular organ that pumps blood in a double circulatory system to provide oxygen to the body.

What is The Heart?
"The heart is a muscular organ that pumps blood around the body in a double circulatory system."
What is the main function of the heart?
Which side of the heart pumps blood to the lungs?
Why are the walls of the left ventricle thicker than the walls of the right ventricle?
Heart Anatomy
The right side pumps deoxygenated blood to the lungs; the left side pumps oxygenated blood to the body.
Coronary arteries supply the heart muscle itself with oxygenated blood.
The left ventricle has much thicker muscular walls because it must pump blood at a higher pressure.
