The release of anti-diuretic hormone from the pituitary gland into the blood stream is controlled by a number of factors. Secretion of anti-diuretic hormone also occurs if the concentration of salts in the blood stream increases, for example as a result of not drinking enough water on a hot day.

Explanation:
The correct answer is option 'D': The secretion of anti-diuretic hormone from your pituitary gland would increase.
When you are outside for a long time on a hot, dry day without anything to drink, your body undergoes several physiological changes to regulate fluid balance and prevent dehydration. One of the key mechanisms involved in maintaining fluid balance is the secretion of anti-diuretic hormone (ADH) from the pituitary gland.
1. Role of ADH:
ADH, also known as vasopressin, is a hormone produced by the hypothalamus and released from the posterior pituitary gland. Its primary role is to regulate the concentration of water in the body by controlling the reabsorption of water in the kidneys.
2. Dehydration and ADH secretion:
During dehydration, the body's water levels decrease, and the blood becomes more concentrated. In response to this, the hypothalamus detects the changes in blood osmolarity (concentration) and triggers the release of ADH.
3. Increased ADH secretion:
The secretion of ADH increases in response to dehydration to conserve water and prevent further fluid loss. ADH acts on the kidneys to increase water reabsorption in the distal tubules and collecting ducts, reducing the amount of water excreted in urine. This helps to retain water in the body and maintain fluid balance.
4. Effects of increased ADH:
Increased ADH secretion leads to the following effects:
- Increased water reabsorption in the kidneys: ADH acts on the distal tubules and collecting ducts of the kidneys to increase their permeability to water. As a result, more water is reabsorbed into the bloodstream, reducing the amount of water lost in urine.
- Decreased urine output: By increasing water reabsorption, ADH reduces the volume of urine produced, helping to conserve water.
- Concentrated urine: The increased reabsorption of water due to ADH leads to the concentration of urine, as more water is retained in the body.
In summary, when you are outside for a long time on a hot, dry day without anything to drink, your body increases the secretion of ADH from the pituitary gland. This hormone acts on the kidneys to increase water reabsorption and reduce urine output, helping to conserve water and maintain fluid balance.
