Bowman's capsule

Capsula glomeruli · Bowmanův váček

Urinary system

Looks like

A microscopic double-walled cup wrapped round each glomerulus, about a million per kidney.

What it does

Catches the fluid filtered from the blood and passes it into the tubule.

Keeping it well

Damage to the filter lets protein leak into urine; frothy urine or swollen ankles should prompt a urine test.
