Question

In response to increased ventricular filling

A. total peripheral resistance increases.
B. sympathetic nerves release norepinephrine.
C. myocardial cells stretch.
D. myocardial contractility in decreases

Answer 1

C) Myocardial cells stretch in response to increased ventricular filling, which leads to increased ventricular contraction strength. Hence, C) is correct.

Step-by-step explanation:

In response to increased ventricular filling, myocardial cells stretch. When the ventricles of the heart fill with blood, the stretching of the myocardial cells triggers a physiological response.

This stretching leads to the release of chemicals that stimulate the heart to contract more forcefully, increasing ventricular contraction strength.
