Decrease, decrease, slight increase, slight decrease, retain less water. 5. No change, no change, increase, decrease, retain less salt and water. 6. No change, no change, increase, decrease, retain less salt and water

Answer 1

The major hormones influencing the restoration of lost blood volume include ADH, aldosterone, and ANH. Angiotensin II is a vasoconstrictor that stimulates the release of ADH and aldosterone, which increase water and sodium reabsorption in the kidneys, respectively. This helps in restoring blood volume and increasing blood pressure.

Step-by-step explanation:

The major hormones influencing the restoration of lost blood volume include ADH, aldosterone, and ANH. Angiotensin II is a vasoconstrictor that stimulates the release of ADH and aldosterone, which increase water and sodium reabsorption in the kidneys, respectively. This helps in restoring blood volume and increasing blood pressure. These mechanisms act principally on the kidney to maintain homeostasis of volume and osmolarity.
