Explanation:
A pair of the kidney is the main excretory organ in humans. Each kidney made millions of tiny units called nephrons.
Each nephron has a glomerulus. It is tuft (network) of capillaries surrounded by a cuplike structure called Bowman’s capsule.
The network of blood capillaries consists of afferent and efferent arterioles. As blood flows through the glomerulus, the fluid from the capillaries gets filtered by podocytes, a specialised layer of cells, called filtration membrane. This glomerular filtration begins the urine formation process.
