Urine Formation in the Kidney

Welcome to this professional exploration of how the human kidney filters and processes our blood.

Presented by Amirhossein Mohammadi, we will examine the intricate mechanics of urine formation.

The nephron is the fundamental functional unit, where the true work of filtration

begins. Each kidney contains millions of these structures, working tirelessly to

maintain homeostatic balance. Blood enters the glomerulus under high hydrostatic pressure via the afferent arteriole.

Water and small solutes are forced into Bowman's capsule, while larger proteins remain behind.

This non-selective filtration captures nearly everything small enough to pass through the membrane.

As the filtrate enters the proximal tubule, essential nutrients are actively reclaimed into
