Ventricular volume decreases during systole
- A. B.The aortic valve is open throughout systole
- A. B.The mitral valve is closed throughout systole
- A. B.The tricuspid valve is closed throughout systole
- A. B.Ventricular volume decreases during systole
Explanation / Answer
The aortic valve is open throughout systole - A (to permit ejection into the aorta and pulmonary artery)
The mitral valve is closed throughout systole - A (atrioventricular valves closes during systole)
The tricuspid valve is closed throughout systole - A (atrioventricular valves closes during systole)
