Study Notes
Cardiovascular Terminology
- Syncope: Refers to a fainting spell, indicating a temporary loss of consciousness due to insufficient blood flow to the brain.
- Systole: The phase in the cardiac cycle during which the heart contracts and expels blood from the ventricles into circulation.
- Pulmonic Valve: Located between the right ventricle and pulmonary artery, it plays a crucial role in directing blood flow toward the lungs.
- Atria: The upper chambers of the heart, characterized by thin walls, responsible for receiving blood.
Heart Anatomy
- Circumflex Artery: A branch stemming from the left main coronary artery, supplying blood to the lateral wall of the left ventricle, essential for heart muscle nutrition.
- Protodiastole: The third phase of systole where blood flow begins to diminish as pressures in atria and ventricles equalize, preparing for the next cycle.
- Mitral Valve: Positioned between the left atrium and left ventricle, essential for maintaining unidirectional blood flow into the ventricle.
- Ventricles: The heart's lower chambers, muscular and responsible for pumping blood out of the heart: right ventricle to the lungs, left ventricle to the body.
Cardiac Structure and Function
- Endocardium: The innermost layer of the heart wall, providing a smooth lining for heart chambers and valves to reduce friction during blood flow.
- Acetylcholine: A neurotransmitter that facilitates communication within the parasympathetic nervous system, playing a vital role in regulating heart rate.
- Septum: The muscular wall that divides the heart into right and left sides, preventing mixing of oxygenated and deoxygenated blood.
- Semilunar Valves: Valves shaped like half moons that regulate blood flow from the ventricles into the arteries (pulmonary and aortic).
- Venules: Small veins that collect deoxygenated blood from capillaries and transport it towards larger veins.
- Capillaries: Tiny blood vessels where the exchange of nutrients and oxygen occurs, connecting arterioles and venules.
