Study Notes
Blood Flow Through the Heart: Mnemonics and Definitions
- Mnemonic "Toilet Paper My Ass" aids in remembering the order of heart valves: Tricuspid, Pulmonary, Mitral, and Aortic.
- Veins, characterized by the suffix "-in-", are responsible for carrying blood into the heart.
- Arteries, identified by the prefix "-A-", carry blood away from the heart.
- The saying "Try before you buy" indicates that the Tricuspid valve precedes the Bicuspid (Mitral) valve in blood flow.
Detailed Flow of Blood Through the Heart
- "Right-Tri-Right, PUL-PUL-PUL, Lung-Pul-Left, BLAA" details the specific flow:
- Right Atrium receives blood from the body.
- Tri signifies blood passes through the Tricuspid Valve to the Right Ventricle.
- Blood exits Right Ventricle through the Pulmonary Semi-Lunar Valve into the Pulmonary Trunk.
- Blood travels through the Pulmonary Arteries to Lung Capillaries for oxygenation.
- Oxygenated blood returns via the Pulmonary Veins to the Left Atrium.
- Bicuspid (Mitral) Valve allows blood flow into the Left Ventricle.
- Blood exits from the Left Ventricle through the Aortic Semilunar Valve into the Aorta for systemic circulation.
Key Relationships
- The phrase "A before V" emphasizes the anatomical order of heart chambers (Atria before Ventricles) and blood vessels (Arteries before Veins).
