Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the hormones involved in the regulation of water-salt balance is produced by the juxtaglomerular apparatus?
A
aldosterone
B
rennin
C
ADH
D
ANH
Explanation: 

Detailed explanation-1: -Therefore the renin-angiotensin system is activated. This causes an increase in water absorption as well as activation of aldosterone. Aldosterone causes sodium to be absorbed and potassium to be excreted into the lumen by principal cells.

Detailed explanation-2: -Antidiuretic hormone (ADH), aldosterone (ALDO), and prolactin (PRL) are hormones that may have interactive effects on kidney function.

Detailed explanation-3: -Renin is rate limiting in the production of angiotensin II (Ang II), a hormone that ultimately integrates cardiovascular and renal function in the control of blood pressure as well as salt and volume homeostasis.

Detailed explanation-4: -Renin is a hormone secreted by the juxtaglomerular cells of the kidney; it interacts with a plasma protein substrate to produce a decapeptide prohormone angiotensin I.
