Question

which of the following is not one of the negative feedback systems that respond to hypovolemic shock? increased secretion of epinephrine and norepinephrine release of local vasoconstrictors release of aldosterone from the adrenal gland release of antidiuretic hormone release of renin from the kidneys

Explanation:

Hypovolemic shock triggers multiple negative - feedback mechanisms to maintain homeostasis. The release of local vasoconstrictors helps to redirect blood flow to vital organs. The release of aldosterone from the adrenal gland promotes sodium and water reabsorption to increase blood volume. The release of antidiuretic hormone (ADH) also increases water reabsorption in the kidneys to boost blood volume. The release of renin from the kidneys initiates the renin - angiotensin - aldosterone system to increase blood pressure and volume. However, the increased secretion of epinephrine and norepinephrine is part of the body's sympathetic nervous system response which is a positive - feedback mechanism in the short - term to rapidly increase blood pressure and heart rate during shock, not a negative - feedback system.

Answer:

increased secretion of epinephrine and norepinephrine
