Body temperature regulation is primarily controlled by the hypothalamus in the brain and involves other mechanisms and hormones, such as sweating, shivering, and the regulation of blood flow to the skin. The primary physiological function of ADH in the human body is to regulate and control the balance of body fluids by conserving water.

Control of body temperature

The primary physiological function of ADH in the human body is to regulate and control the balance of body fluids by conserving water. It increases the permeability of the renal collecting ducts to water. This allows the kidneys to reabsorb more water from the urine, reducing the volume of urine and concentrating it.

a
Conservation of water by increasing water reabsorption in the kidneys
QuestionChoice
The hormone that primarily regulates blood pressure by increasing heart rate is epinephrine, also known as adrenaline. In addition, norepinephrine, released by the adrenal glands, also plays a role in regulating blood pressure and heart rate. Both hormones are part of the sympathetic nervous system's response to stress and are essential for adjusting cardiovascular function during fight-or-flight situations. The primary physiological function of ADH in the human body is to regulate and control the balance of body fluids by conserving water.

Regulation of blood pressure by increasing heart rate
QuestionChoice
When ADH is released into the bloodstream, it binds to receptors on the smooth muscle cells of blood vessels to bring about vasoconstriction. This leads to the contraction of smooth muscle, resulting in a reduction in the diameter of the blood vessels, which, in turn, increases vascular resistance. Increased vascular resistance leads to a rise in blood pressure. This answer is therefore incorrect.

d
Vasoconstriction to reduce blood pressure
QuestionChoice
The stretching of the bladder wall as it fills with urine is an important mechanism that stimulates the urge to urinate. When the bladder reaches a certain level of distension, mechanoreceptors in the bladder wall send signals to the brain, indicating that it's time to empty the bladder. ADH reduces urine production by concentrating urine. As a result, one may feel less urgency to urinate when ADH levels are higher, however, this is not its direct effect.
