Urine Formation in the Nephron

Welcome to this exploration of urine formation within the intricate structures of the human kidney.

Presented by Amirhossein Mohammadi, a medical student dedicated to understanding complex physiological processes.

The process begins as blood enters the nephron through the afferent arteriole at high pressure.

As blood reaches the glomerulus, the intense pressure forces plasma components through the filtration

membrane. Water, glucose, and ions move forcefully into Bowman's

capsule, leaving larger proteins and blood cells behind. Once inside the

tubule, the filtrate contains essential nutrients that the body cannot afford to lose.

During reabsorption, glucose and water are actively returned to the blood stream via the
