THE ABSENCE OF ANTI-DIURETIC HORMONE IN HUMANS RESULTS IN
- A. decreasing dehydration
- B. drastic dehydration ✓
- C. eliminating dehydration
- D. increasing dehydration
The answer to the question is: B. drastic dehydration
The absence of anti-diuretic hormone (ADH) in humans results in drastic dehydration. ADH, also known as vasopressin, is a hormone produced by the hypothalamus and released by the pituitary gland. Its primary function is to regulate the amount of water excreted by the kidneys. When ADH is absent or deficient, the body is unable to retain water effectively, leading to a significant loss of fluids and ultimately resulting in severe dehydration.
In the absence of ADH, the kidneys are unable to reabsorb water as efficiently as they normally would. This leads to increased urine production and excretion, causing a rapid loss of bodily fluids. As a result, the body becomes dehydrated, with symptoms such as extreme thirst, dry mouth, decreased urine output, dark-colored urine, fatigue, dizziness, and in severe cases, confusion and unconsciousness.
Furthermore, without ADH to regulate water balance in the body, individuals may experience electrolyte imbalances and disturbances in blood pressure regulation. These physiological disruptions can have serious implications for overall health and wellbeing.
In summary, the absence of anti-diuretic hormone in humans leads to drastic dehydration due to the inability of the kidneys to retain water effectively, resulting in excessive fluid loss and potential complications related to electrolyte imbalances and blood pressure regulation.
