Study Notes
Blood Vessels and Chambers of the Heart
- Superior Vena Cava: Major vein carrying deoxygenated blood from the upper body to the right atrium.
- Inferior Vena Cava: Major vein transporting deoxygenated blood from the lower body to the right atrium.
- Pulmonary Vein: Carries oxygenated blood from the lungs to the left atrium.
Heart Chambers
- Right Atrium: Receives deoxygenated blood from the body via the superior and inferior vena cavae; pumps blood into the right ventricle.
- Left Atrium: Receives oxygenated blood from the lungs through the pulmonary veins; pumps blood into the left ventricle.
- Right Ventricle: Pumps deoxygenated blood to the lungs via the pulmonary artery for oxygenation.
- Left Ventricle: Pumps oxygenated blood to the entire body through the aorta; has thicker walls due to higher pressure requirements.
Valves of the Heart
- Tricuspid Valve: Located between the right atrium and right ventricle, prevents backflow of blood during ventricular contraction.
- Bicuspid/Mitral Valve: Positioned between the left atrium and left ventricle, ensures one-way blood flow from atrium to ventricle.
Circulation Pathways
- Pulmonary Circulation: Movement of blood from the right side of the heart to the lungs and back to the left side, crucial for oxygenation.
- Systemic Circulation: Flow of oxygen-rich blood from the left side of the heart to the rest of the body and back to the right side.
Structural Components
- Septum: Thick wall dividing the left and right sides of the heart, preventing mixing of oxygenated and deoxygenated blood.
Major Arteries
- Pulmonary Artery: Carries deoxygenated blood from the right ventricle to the lungs for gas exchange.
- Aorta: The largest artery in the body, delivering oxygenated blood from the left ventricle to the systemic circulation.
