Study Notes
Heart Chambers
- Left Ventricle: Pumps oxygenated blood to the body under high pressure via the aorta.
- Right Ventricle: Moves deoxygenated blood to the lungs at low pressure through the pulmonary artery.
- Left Atrium: Receives oxygenated blood from the lungs and transfers it to the left ventricle.
- Right Atrium: Collects deoxygenated blood from the body and pushes it into the right ventricle.
Major Blood Vessels
- Aorta: Main artery that carries oxygenated blood from the heart to the rest of the body; runs in front of the backbone.
- Superior Vena Cava: Transports deoxygenated blood from the head, arms, and upper body to the heart.
- Inferior Vena Cava: Brings deoxygenated blood from the lower body to the heart.
Valves of the Heart
- Tricuspid Valve: Prevents backflow of blood into the right atrium. Located between the right atrium and right ventricle.
- Pulmonary Valve: Controls blood flow from the right ventricle to the pulmonary artery, preventing backflow into the heart.
- Aortic Valve: Ensures one-way blood flow from the left ventricle to the aorta.
- Mitral Valve: Positioned between the left atrium and left ventricle, featuring two tapered cusps.
Blood Vessels and Circulation
- Coronary Artery: Supplies blood to the heart muscle itself.
- Arteries: Carry oxygenated blood away from the heart to the body's tissues.
- Veins: Transport deoxygenated blood back to the heart.
- Pulmonary Veins: Large vessels that carry oxygenated blood from the lungs to the left atrium.
- Pulmonary Arteries: Transport deoxygenated blood from the heart to the lungs; unique among arteries.
Other Key Concepts
- Blood Pressure: Vital for diagnosis, indicates the force exerted by circulating blood on arteries and is influenced by heart rate and vessel elasticity.
- Septum of the Heart: Separates the heart's upper chambers (left and right atria).
- Chordae Tendineae: Connects papillary muscles to the tricuspid and mitral valves, helping maintain valve position during heart contractions.
