If blood pressure drops very low (MAP is below 80mmHg)renin enzyme will be secreted by granular cells.Which of the following is not likely to occur?
A) Blood plasma and extracellular fluids volume will increase
B) Glomerular filtration rate (GFR) will decrease
C) Net filtration pressure (NFP) will decrease
D) Kidney perfusion will increase

Quizplus · Accepted Answer

When renin is secreted due to low blood pressure, it initiates the renin-angiotensin-aldosterone system (RAAS) which leads to the retention of sodium and water, increasing blood volume and pressure. This process does not directly increase kidney perfusion; instead, it aims to restore blood pressure to normal levels. Increased kidney perfusion is not a direct effect of renin secretion but rather a goal of the physiological adjustments it promotes.
