Moreover, the kidneys are involved in the production of red blood cells by releasing erythropoietin, a hormone that stimulates red blood cell production in the bone marrow.
In summary, while urine production is a significant function of the kidneys, they also perform a range of other essential tasks including fluid balance regulation, electrolyte balance maintenance, blood pressure control, waste product elimination, and red blood cell production. These functions collectively contribute to the overall well-being and health of the body, highlighting the critical importance of healthy kidney function.
