Study Notes
Heart Anatomy and Circulatory Components
- Mitral or Bicuspid Valve: A valve located between the left atrium and left ventricle, facilitating blood flow from the atrium to the ventricle while preventing backflow.
- Aorta: The largest artery in the body, responsible for distributing oxygenated blood from the heart to all parts of the body.
- Semilunar Valve: Valves located at the bases of the aorta and pulmonary arteries, ensuring one-way blood flow from the ventricles into these arteries during contraction.
- Pulmonary Artery: Transports deoxygenated blood from the right ventricle to the lungs for oxygenation.
- Inferior Vena Cava: A large vein that carries deoxygenated blood from the lower body directly to the right atrium of the heart.
- Superior Vena Cava: A large vein that brings deoxygenated blood from the upper body to the right atrium.
- Pulmonary Veins: Blood vessels that carry oxygenated blood from the lungs back to the left atrium of the heart.
- SA Node: The sinoatrial node, known as the heart's natural pacemaker, which initiates electrical impulses to regulate heartbeats.
