Study Notes
Cardiovascular Terminology
- Cardiovascular: Relates to the heart and blood vessels.
- Vascular: Involves the structures that convey blood or lymph.
- Cardiac: Pertains specifically to the heart's function and structure.
Heart Chambers
- Atrium: Upper chambers that receive blood before it enters the ventricles.
- Ventricle: Lower chambers that pump blood to the arteries.
Heart Structure
- Septum: Thick wall dividing the heart's left and right sides, preventing mixed blood.
- Apex: Lower tip of the heart that rests on the diaphragm.
Heart Valves
- Valve: Structures controlling blood flow; includes tricuspid, pulmonary, mitral, and aortic valves.
- Tricuspid Valve: Located between the right atrium and ventricle; has three cusps.
- Pulmonary Valve: Connects the right ventricle to the pulmonary arteries.
- Mitral Valve: Between the left atrium and ventricle; known as the bicuspid valve.
- Bicuspid Valve: Two-flapped valve; essentially the same as the mitral valve.
- Aortic Valve: Situated between the left ventricle and the aorta.
Heart Layers and Support Structures
- Myocardium: Thick muscular layer that contracts to pump blood.
- Chordae Tendineae: Ropelike structures that prevent backflow in valves.
- Endocardium: Inner layer of the heart’s wall made of epithelium and connective tissue.
- Pericardium: Double-layered membrane surrounding the heart, filled with fluid.
- Visceral Pericardium (Epicardium): Inner layer of pericardium directly on the heart.
- Parietal Pericardium: Outer layer forming the pericardial sac.
Thoracic Anatomy
- Thoracic Cavity: Encloses the lungs and mediastinum.
- Mediastinum: Space between the lungs that houses the heart, vessels, and trachea.
Circulatory Terms
- Cardiothoracic: Related to both heart and thoracic cavity.
- Vasculature: Network of blood vessels specific to an organ.
- Lumen: Central opening in blood vessels for blood flow.
- Endothelium: Smooth inner cell layer in blood vessels promoting blood flow.
Vascular Functions
- Intima: Innermost membrane lining blood vessels, equivalent to endothelium.
- Artery: Blood vessel carrying blood away from the heart.
- Vasoconstriction: Narrowing of blood vessels due to smooth muscle contraction.
