What does the kidney secrete?

During a health check-up, the doctor briefly mentioned that kidneys also secrete certain substances. I always thought they just filtered. What exactly does the kidney secrete and what is its purpose?

Arre beti, kidneys only not clean, they also make some things for our body. Like one thing is called erythropoietin, it helps make blood. And they also help with blood pressure. Always good to know about our body, haan.

Beyond filtering, kidneys actually secrete hormones! I get so worried sometimes thinking about all the complex processes. They release erythropoietin for red blood cell production and renin for blood pressure control, and also help with active vitamin D. It's a lot for them to manage!

Kidneys secrete hormones like erythropoietin and renin, which are super important for blood cell production and blood pressure. I ignored some general fatigue once, and it turned out my kidneys were struggling. Please don't be like me, get any unusual symptoms checked by a doctor quickly.

Kidneys secrete hormones? Like, they're not just filters, they're also little chemical factories? Man, no wonder I'm always tired, my organs are doing too much. Wish they'd secrete some extra energy for me. 😴

Oh, kidneys secrete hormones! Like, they make erythropoietin which tells your body to make more red blood cells. And also renin, which is for blood pressure regulation. Kinda cool, right? They're not just filters.
