Describe how intoxication affects the excretory system
A) Drinker loses more water from the body than usual
B) more blood flow to the skin surface
C) Sensations and perceptions become less clear
D) too much alcohol in the stomach may cause vomiting
The Correct Answer and Explanation is:
The correct answer is A) Drinker loses more water from the body than usual.
Explanation:
Intoxication, especially from alcohol consumption, has a significant impact on the excretory system, particularly by affecting hydration levels in the body. The primary mechanism behind this is alcohol’s ability to inhibit the release of an antidiuretic hormone (ADH), also known as vasopressin. ADH plays a key role in regulating the body’s water balance by promoting water reabsorption in the kidneys. When alcohol is consumed, it suppresses the secretion of ADH, which reduces the kidneys’ ability to reabsorb water. As a result, the kidneys excrete more water than usual, leading to increased urine production, a condition known as diuresis. This loss of water can cause dehydration, which is one of the key effects of alcohol intoxication on the body.
Excessive urine output can lead to a state of dehydration, which is why individuals often experience symptoms such as dry mouth, headache, and fatigue after drinking. In severe cases, dehydration can lead to more serious complications, including kidney damage and electrolyte imbalances, which can affect the functioning of other body systems.
While other options might seem plausible in describing the effects of alcohol, they are not as directly related to the excretory system. For example, B) more blood flow to the skin surface is more related to alcohol’s vasodilatory effects, which increase skin blood flow and cause a sensation of warmth. C) Sensations and perceptions become less clear is a result of alcohol’s central nervous system depressant effects, which impair cognitive functions. Finally, D) too much alcohol in the stomach may cause vomiting is related to alcohol’s irritative effects on the gastrointestinal system rather than the excretory system.
In summary, alcohol’s effect on ADH secretion leads to increased urination, which results in a greater loss of water from the body than normal, contributing to dehydration and affecting the excretory system.
