The thickest layer of tissue in the heart wall is the: ____ 2. The internal layer of tissue in the heart is: ____ 3. The right atrioventricular valve is also called the: ____ 4. How is the heart muscle supplied with oxygen and nutrients?
Understand the Problem
The question is asking about various aspects of heart anatomy and physiology, specifically layers of heart tissue, types of heart valves, and blood supply to the heart muscle.
Answer
1. Myocardium 2. Endocardium 3. Tricuspid 4. By the coronary arteries
- Myocardium 2. Endocardium 3. Tricuspid 4. By the coronary arteries, which branch from the aorta
Answer for screen readers
- Myocardium 2. Endocardium 3. Tricuspid 4. By the coronary arteries, which branch from the aorta
More Information
The myocardium is the thickest layer due to its role in contraction. The endocardium lines the inner heart chambers. The tricuspid valve is the right AV valve, and coronary arteries supply the heart with oxygenated blood.
Tips
Ensure correct identification of layers and valves by understanding their positions and functions.
