What is the heart?

The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, as well as assisting in the removal of metabolic wastes. In humans, the heart is located between the lungs, in the middle compartment of the chest.

How does the heart pump blood to the rest of the body

The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.

what are the four chambers of heart?

Right Atrium Left Atrium Right Ventricle Left Ventricle

Pulmonary Artery Pulmonary Vein Aorta Vena Cava

Blood flows to and from the heart through?

Blood enters the heart through two large veins, the inferior and superior Vena Cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the ventricle contracts, blood leaves the heart through the Pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
