Biology Human Heart

Structure of Human Heart

The human heart is a vital organ responsible for pumping oxygenated blood throughout the body and removing deoxygenated blood through level.

Chambers of the Heart

The heart is divided into four chambers: two atria (singular: atrium) and two ventricles. The atria are the upper chambers, and the ventricles are the lower chambers.

Right Atrium: The right atrium receives deoxygenated blood from the body through two large veins called the superior vena cava and the inferior vena cava.
Right Ventricle: The right ventricle pumps the deoxygenated blood to the lungs through the pulmonary artery.
Left Atrium: The left atrium receives oxygenated blood from the lungs through four pulmonary veins.
Left Ventricle: The left ventricle pumps the oxygenated blood to the rest of the body through the aorta, the largest artery in the body.

Valves of the Heart

The heart contains four valves that prevent backflow of blood and ensure proper blood flow.
