Describe the pathway of blood through the kidney ( short please ) Point form
1. Renal artery carries oxygenated blood into the kidney.
2. Blood enters the kidney through the renal hilum.
3. Renal artery branches into smaller arterioles called afferent arterioles.
4. Afferent arterioles deliver blood to the glomerulus, which is a network of tiny blood vessels in the renal corpuscle.
5. Glomerulus filters blood under high pressure, allowing waste products and excess fluid to pass into the renal tubules.
6. Filtered blood leaves the glomerulus through efferent arterioles.
7. Efferent arterioles divide into a network of capillaries called peritubular capillaries.
8. Peritubular capillaries surround the renal tubules, reabsorbing essential substances like glucose and electrolytes back into the bloodstream.
9. Blood then flows into the renal vein, taking the filtered and reabsorbed blood out of the kidney.
10. Renal vein transports deoxygenated blood back to the heart.
