Question

. The ascending limb of loop of Henle : 1) Is impermeable to electrolytes 2) Allows transport of electrolytes actively or passively 3) Allow the concentrated filtrate pass upward and further concentrate it due to the passage of electrolytes to the medullary fluid 4) Is permeable to water

Answer 1

Answer:

Allows transport of electrolytes actively or passively

Step-by-step explanation:

It depends upon the needs

Answer 2

Answer:

(2) allows transport of electrolytes actively or passively

Step-by-step explanation:

the loop of henle is divided into 3 functionally distinct segments: thin descending limb, thin ascending limb and thick ascending limb

• primary function is to maintain the osmotic gradient
• the descending limb is freely permeable to water and ions
• the thin ascending limb is permeable to salts and less permeable to water.
• thick segment is capable of reabsorption of sodium chloride, potassium , calcium, bicarbonate and considerable amount of magnesium
• the thick ascending limb is completely impermeable to water but actively transports salts from the filtrate

hence, answer is (2) allows transport of electrolytes actively or passively
