Renal cortex

Definition

The renal cortex is the outer layer of the kidney that contains the glomeruli and convoluted tubules. It plays a crucial role in filtering blood to form urine.

5 Must Know Facts For Your Next Test

1. The renal cortex houses nephrons, which are essential for filtering blood and forming urine.
2. It receives a significant portion of the kidney's blood supply due to its vital filtration function.
3. The renal cortex is involved in the reabsorption of nutrients, electrolytes, and water from filtrate.
4. Hormones like aldosterone and antidiuretic hormone influence reabsorption processes in the renal cortex.
5. Damage to the renal cortex can lead to impaired kidney function and issues with waste excretion.
