Question

1. Which ions can pass the glomerular capillaries into the capsule? Which can’t? Why?
2. What is ADH? What is its function?
3. Which two hormones regulate sodium reabsorption and blood volume?

Please, type the answers 1... 2...3...

Answer 1

Small ions like sodium, potassium, bicarbonate ions, glucose, water can pass through glomerular capilaries.

And haemoglobin in erthyrocytes, roteins which have low permeability cannot pass through glomerular capillaries.

ADH means anti diruetic harmone.

It's function is to maintain the concentration of urine.

When there is more amount of water in the body, it helps in excreation of water and salts.

And when there is low amount of water ,it helps in absorption of salts and water.

2 harmones which regulate sodium absorption and blood volume are-

Aldosterone, anti diruetic harmone

These both harmones regulate blood volume and help in maintaining the concentration of urine.
