Question:
Comment upon the hormonal regulation of selective reabsorption.
Solution:
Selective reabsorption is the process in which some molecules like glucose, ions and certain amino acids get reabsorbed from the filtrate as they pass through the
neuron. ADH i.e. Antidiuretic hormone and ANF i.e. Atrial Natriuretic Factor are the hormones which monitor the function of the kidney. ADH functions as the facilitation
of the reabsorption of water from DCT. The adrenal cortex is activated by Angiotensin II as a result of which aldosterone is released. Aldosterone, in turn, induces the
DCT to absorb more ions and water. ANF regulates blood flow by causing vasodilation and increasing excretion of sodium.
