Potassium has to stay in a tight range for nerves and muscles to work properly, and the kidneys manage most of that balance. As blood moves through each nephron, potassium enters the early filtered fluid. Later sections of the nephron take over and decide how much should stay and how much should leave the body. Special cells in the distant parts of the tubules use energy powered pumps to guide these adjustments with precision. When potassium levels in the blood climb too high, these cells push e

Adrenal Glands: The Basics 🫘 → These glands sit atop each kidney and are cone-shaped or triangular → The gland is split into two major parts: the adrenal cortex and the adrenal medulla 🫘Adrenal cortex: releases stress hormones like aldosterone and cortisol 🏃Adrenal medulla: releases epinephrine and norepinephrine (encourages “fight or flight” response & alertness) 🧠Save this for later to connect the dots on diseases and hormone imbalance!
