Question

To increase the reabsorption of water, which parts of the kidney tubules are involved

a) Distal convoluted tubule and collecting duct
b) Proximal convoluted tubule and Loop of Henle
c) Glomerulus and Loop of Henle
d) Distal convoluted tubule and proximal convoluted tubule

Answer 1

The distal convoluted tubule and collecting duct are involved in increasing the reabsorption of water in the kidney tubules.

Step-by-step explanation:

The correct answer is a) Distal convoluted tubule and collecting duct. Both the distal convoluted tubule and the collecting duct play important roles in reabsorbing water in the kidney tubules.

The distal convoluted tubule reabsorbs water under the influence of antidiuretic hormone (ADH), which is secreted by the posterior pituitary gland. ADH helps increase the permeability of the distal convoluted tubule to water, allowing more water to be reabsorbed back into the bloodstream.

The collecting duct further reabsorbs water along with other solutes, concentrating the urine. This concentration process helps maintain water balance in the body.
