Study Notes
Structure and Function of the Heart
- The human heart is a four-chambered organ located centrally in the chest.
- The size of the heart is approximately equal to a person's clenched fist.
- The heart is divided by a muscular wall known as the septum.
Heart Chambers
-
Atria: Serve as the receiving chambers for blood.
- Right Atrium: Receives oxygen-poor blood from the body.
- Left Atrium: Receives oxygen-rich blood from the lungs.
-
Ventricles: Function as the pumping chambers of the heart.
- Right Ventricle: Pumps oxygen-poor blood to the lungs for oxygenation.
- Left Ventricle: Pumps oxygen-rich blood to the rest of the body.
Heart Valves
- Mitral Valve: Located between the left atrium and left ventricle.
- Aortic Valve: Controls blood flow from the left ventricle into the aorta.
- Tricuspid Valve: Located between the right atrium and right ventricle.
- Pulmonic Valve: Regulates blood flow from the right ventricle to the lungs.
