Question

Quizplus · Accepted Answer

The kidney is responsible for producing renin, which plays a crucial role in regulating blood pressure. Renin is secreted by specialized cells in the kidneys in response to factors such as low blood pressure, low blood volume, or low sodium levels. It then activates a cascade of hormones, including angiotensin and aldosterone, that work to increase blood pressure and maintain fluid balance. While the kidney also produces erythropoietin, this hormone is primarily responsible for stimulating the production of red blood cells and does not play a direct role in blood pressure regulation. Angiotensin is produced as part of the renin-angiotensin-aldosterone system and is not directly produced by the kidney. The kidney produces renin, which starts a cascade of reactions that eventually results in the production of angiotensin II. Angiotensin II causes vasoconstriction and the release of aldosterone, which helps to increase blood pressure. The kidney also produces erythropoietin, which stimulates the production of red blood cells, but this is not directly involved in regulating blood pressure.
