Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride, and about 70% of the sodium reabsorption occurs here. Sodium reabsorption is tightly coupled to passive water reabsorption, meaning when sodium moves, water follows.

Hope this helps you!

Answer:

Reabsorption of ions by tubules of kidneys is enhanced by

(B) Aldosterol

Explanation:

  • The process of removing water and other substances from glomerular capillaries and transferring them into the bloodstream in order to maintain homeostasis is known as renal tubular reabsorption. This process is primarily carried out in the proximal tubule by osmotic pressure and active transport of the tubular epithelial cells.
  • The kidney nephron's distal convoluted tubule (DCT) is located between the collecting tubule and the loop of Henle. Potassium, sodium, calcium, and pH are all regulated in part by DCT.
  • The adrenal glands, which are found above the kidneys, create the hormone aldosterone in their cortex. The hormone stimulates the reabsorption of salt and water, which increases blood volume.
  • The method by which solutes and water are removed from the filtrate and returned to your bloodstream is known as tubular reabsorption.
  • Reabsorption refers to the fact that these substances are being absorbed for the second time; the first time was when they entered the bloodstream from the digestive tract after a meal. Secreting K+ and absorbing Na+  regulate sodium and potassium levels.
