10. Urinary system

This system is meant to remove the wastes and toxins from the body.

Any substance in the body is first converted to a water-soluble form by the liver.

This is transported by the blood to the kidneys of the urinary system. There the blood flows through the glomerulus of the nephron and gets filtered to lose those wastes.

The load on the kidney is reduced as other organs like the skin, lungs, and saliva also participate in the excretion of waste from the body.
