Question

The following factors enhance renin release from the kidney except:

1 Reduction in blood volume
2 Fall in blood pressure
3 Volume overload
4 Enhanced sympathetic activity​

Answer 1

All the given factors enhance renin release from the kidney except volume overload (option 3).

• Renin is an enzyme released by particular kindey cells in reaction to circumstances that cause the body's water and blood to become unbalanced.

• When the following action is recognized in the body, this enzyme is released:

1. Blood volume is low.
2. Hypotension (low blood volume) causes low blood pressure.
3. Sympathetic nerve activity has increased.

• The renin released activates a series of angiotensin enzymes, which help to balance and restore the body's renin-angiotensin system.
• As a result, the incorrect response is volume overload, because this enzyme is produced when arterial blood volume falls below a certain threshold.
