Exercise 4

A patient develops a sudden drop in blood pressure.

a. Diagram the reactions that take place to ensure adequate blood pressure within the nephrons.

b. How do these reactions increase blood volume?

c. When blood pressure returns to normal, how does the kidney respond?

Step 1 of 3

a.

Renin-angiotensin-aldosterone system:

It is a hormone system of the body, which regulates the flow of blood in the body.

• The system responds to blood pressure changes and also sodium content of plasma

• Low sodium content in plasma results in low volume of blood and decreased blood pressure

• When the blood flow in kidney is decreased, prorenin of the blood is converted into renin by juxtaglomerular nephron of the kidney

Reaction associated is,
