Which is true about the physiology of neuroendocrine compensatory mechanism?
A)Increased venous return increases ventricular filling and myocardial stretch, increasing the force of contraction.
B)Decreased cardiac output stimulates the sympathetic nervous system and catecholamine release.
C)Increased renal perfusion stimulates the renin-angiotensin system.
D)Antidiuretic hormone is released from the adrenal gland.

Question

A)In the neuroendocrine response, the cardiac output is decreased. This stimulates the sympathetic nervous system, causing catecholamine release. Decreased cardiac output combined with decreased renal perfusion stimulates the renin-angiotensin system. In addition, antidiuretic hormone is released from the posterior pituitary. In the Frank-Starling mechanism, increased venous return increases ventricular filling and myocardial stretch, increasing the force of contraction.
B)In the neuroendocrine response, the cardiac output is decreased. This stimulates the sympathetic nervous system, causing catecholamine release. Decreased cardiac output combined with decreased renal perfusion stimulates the renin-angiotensin system. In addition, antidiuretic hormone is released from the posterior pituitary.
