Explanation / Answer
Question 1
Answer
A)
The blood plasma volume may change according to intake of water. If you increases in water intake, increases the plama volume and decrease plasma volume if you drink less water. The body water reduced in normal conditions in the form of air, sweat, urine even at rest.
The decreased intake of water leads to decreased level of blood water and other tissues that can develop dehydration.
Dehydration condition significantly decreases the blood plasma volume.
B)
The osmolarity is the amount of solute particle present in one liter solvent. If you drink more water, increases blood plasma volume. That decreases the solute concentration that indicate decreased Osmolarity. In case of dehydration decreased level of blood plasma volume. that increases the solute concentration thereby increases the blood plasma Osmolarity.
Question 2
Answer
The changes in the blood plasma volume and osmolarity can be detected by osmoreceptors in the hypothalamus.
In Dehydration the decreased blood plasma volume and increased plasma osmolarity dected by osmoreceptors that inturn activate the release of ADH from posterior pituitary gland. The so formed released ADH increases the reabsorption of water from collecting tubules to attain the homeostasis.
Question 3
Answer
The main hormone involved in the regulation and restore of homeostasis is Antidiuretic hormone (ADH). It is also called as Vasopressin. ADH is secreted by Supraoptic nucleus of the Hypothalamus.
This hormone is stored and relesed by endocrine gland that is Posterior pituitary gland.
