Question

i. What are the physiological mechanisms that are activated in the body when an animal is suffering from a hemorrhage?

a. activation of the parasympathetic nerve activity inducing renin secretion

b. renin secretion -> angiotensin II, aldosterone, and ADH increase

c. a decrease in the concentration of ADH will be observed -> water excretion will occur

d. renin secretion with vasodilation

ii. In the nephron, where will most of the water, sodium, chloride, and bicarbonate be reabsorbed?

a. proximal tubules

b. distal tubules

c. thick loop of henle

d. medullary and cortical collecting tubules

iii. pressures that contribute to ventilation include

a. The proprioreceptors sense stretching and adjust to the intrapulmonic and intrapleural pressures

b. intrapulmonic pressure and intrapleural decreases during expiration and increases during inspiration

c. intrapulmonic pressure decreases, intrapleural pressure increases during inspiration and both increase during expiration

d. intrapulmonic pressure and intrapleural decreases during inspiration and increases during expiration

Answer 1

Question No.1

Answer :- b. renin secretion -> angiotensin II, aldosterone, and ADH increase

Explanation : Haemorrhage is an abnormal discharge of blood either externally or internally and to conserve the blood and plasma in the body renin is secreted by physiological means that ultimately release Aldosterone that increase the rate of reabsoption water and salt from nephron loop and maintain homeostasis.

Question No.2

Answer :- a. proximal tubules

Explanation :Nephron is the functional unit of kidney which consist of a PCT, Loop of Henley, DCT and collecting duct and most of the water, sodium, chloride, and bicarbonate are reabsorbed by proximal convoluted tubule .

Question No.3

Answee :- b. intrapulmonic pressure and intrapleural decreases during expiration and increases during inspiration... Thanks dear
