The loop of the nephron (loop of Henle) Select one: a. is necessary for glucose reabsorption. b. creates a low osmotic pressure in the medulla. c. creates a high osmotic pressure in the medulla. d. creates a low osmotic pressure in the cortex. e. creates a high osmotic pressure in the cortex.

c. creates a high osmotic pressure in the medulla

Explanation:

Loop of henle is a nephron the runs from proximal to distal convulated tubule. It create in the medulla an area of high urea concentration using energy to create the concentration gradients. Henle of loop is divided into four compartment.

1. thin ascending limb of loop of henle- it is highly permeable to water

2. thin decending limb of loop of henle is not permeable to water but Ion

3. ascending limb of loop- reabsorbtion of calcium, sodium and potassium ion from urine takes place here

4.Cortical thick ascending limb- It drains urine into distal convulated tubule.

c. creates a high osmotic pressure in the medulla.

Explanation:

The loop of Henle is a U- long shaped structure which is classified as a nephron is majorly found in the medulla. The loop of Henle helps in the reabsorption of water and salt in the urine which are found in the renal tubule.

The loop of Henle uses the mechanism of creating a high osmotic pressure in the medulla in order to make this reabsorptions possible.

this is a good question! i'll do some research and come back when i have the answer!

that is true   : ) hope this you
