The correct answer is option 'A': When someone drinks a lot of water, ADH release is suppressed.
Explanation:
ADH (antidiuretic hormone), also known as vasopressin, is a hormone produced by the hypothalamus and released from the posterior pituitary gland. It plays a crucial role in the regulation of kidney function, particularly in water balance.
When someone drinks a lot of water, the body's water levels increase, leading to a decrease in blood osmolality (concentration of solutes in the blood). In response to this decrease, the hypothalamus senses the change and inhibits the release of ADH.
This process can be explained in detail:
1. Control of ADH release:
- ADH release is tightly regulated by negative feedback mechanisms.
- The hypothalamus contains specialized cells called osmoreceptors, which detect changes in blood osmolality.
- When blood osmolality increases, indicating dehydration and higher solute concentration, the osmoreceptors stimulate the release of ADH.
- Conversely, when blood osmolality decreases, indicating excess water intake and lower solute concentration, the osmoreceptors suppress the release of ADH.
2. Effect of drinking a lot of water:
- When someone drinks a large amount of water, it dilutes the blood, leading to lower blood osmolality.
- The osmoreceptors in the hypothalamus detect this decrease in osmolality and inhibit the release of ADH.
- As a result, less ADH is released into the bloodstream.
3. Actions of ADH:
- ADH acts on the kidneys to regulate water reabsorption.
- When ADH is present, it binds to specific receptors in the kidney tubules, increasing their permeability to water.
- This allows more water to be reabsorbed back into the bloodstream, reducing urine output and conserving water in the body.
- In the absence of ADH, the kidney tubules remain less permeable to water, resulting in increased urine output and excretion of excess water from the body.
In summary, when someone drinks a lot of water, the decrease in blood osmolality is detected by the osmoreceptors in the hypothalamus, leading to the suppression of ADH release. This helps to regulate water balance by increasing urine output and preventing excessive water retention.
