Question 1
What is the process that ensures mitral and tricuspid valve closure after the ventricles are
filled with blood?
Chordae tendineae relax, which allows the valves to close.
Increased pressure in the ventricles pushes the valves to close.
Trabeculaecarneae contract, which pulls the valves closed.
Reduced pressure in the atria creates a negative pressure that pulls the valves closed.
Question 2
What is an expected change in the cardiovascular system that occurs with aging?
Arterial stiffening
Decreased left ventricular wall tension
Decreased aortic wall thickness
Arteriosclerosis
