Question

full form of DCT, ADH and RAAS. ​

Answer 1

Answer:

Full form of DCT is Distal Convoluted Tubule.

Full form of ADH is Antidiuretic hormone (ADH).

Full form of RAAS is renin angiotensin aldosterone system.

ADH

• It is also called Vasopressin.
• Prevents loss of H2O in the urine.
• Reabsorption of H2O and minerals at DCT and collecting duct.

DCT

• It is part of kidney nephron between the loop of Henle and the collecting duct.
• It is lined by the simple cuboidal epithelium.

Juxta glomerular apparatus (JGA) is a special sensitive region formed by cellular modification in DCT and afferent arteriole at the location of their contact.

Answer 2

Answer:

ADH affects the principal cells by increasing their permeability to water as indicated by the thick broken walls of the late distal convoluted tubule and the collecting duct. This permits the reabsorption of water (block arrow) into the vasa recta. The secretion of this hormone is controlled by two mechanisms.
