Question

Quizplus · Accepted Answer

Renin is secreted when special cells in the distal convoluted tubule,called the macula densa,sense changes in blood volume and pressure.When the macula densa cells sense that blood volume,blood pressure,or blood sodium levels are low,renin is secreted.Renin then converts angiotensinogen into angiotensin I.This leads to a series of reactions that cause secretion of the hormone aldosterone.This hormone increases kidney reabsorption of sodium and water,increasing blood pressure,blood volume,and blood sodium levels.Inappropriate or excessive renin secretion is a major cause of persistent hypertension.Renin has no impact on Alzheimer's disease,diabetes mellitus,or viral hepatitis.
