Question

How does osmolarity of the blood maintain homeostasis?

Answer 1

In the steady state, the osmolarity of the blood is about 300 mOsm/L.

In the steady state, the osmolarity of the blood is about 300 mOsm/L.Blood flowing through the descending loop of Henle loses water by osmosis. The osmolarity increases to 1200 mOsm/L as solutes become more concentrated.

In the steady state, the osmolarity of the blood is about 300 mOsm/L.Blood flowing through the descending loop of Henle loses water by osmosis. The osmolarity increases to 1200 mOsm/L as solutes become more concentrated.The ascending limb is permeable to salt but not to water. NaCl exits into the medulla, where the osmolarity is 1200 mOsm/mol. The osmolality decreases to 100 mOsm/L.

NaCl exits into the medulla, where the osmolarity is 1200 mOsm/mol. The osmolality decreases to 100 mOsm/L.Thus, the two limbs cooperate with each other. The filtrate becomes saltier as it moves down the descending limb. The ascending limb exploits this concentration of NaCl to help maintain a high osmolarity in the medulla.

Answer 2

Answer:

This osmolarity is largely a function of how much water is retained within the body.

• In the process of maintaining fluid balance homeostasis, small deviations from normal blood osmolarity occur throughout each day.

• these deviations serve as stimuli that influence the release of ADH from the posterior pituitary.
