Egestion, Biology

After the food intake is over, the food gets digested, assimilated and finally egested through the kidneys and anus. The urinary system:

• Filters waste materials from the blood.

• Regulates blood volume.

• Conserves useful materials, such as water, nutrients, and ions. The urinary system regulates how much water the body retains and how much it excretes

• maintains pH balance in the body

• Kidneys eliminate: blood-from the renal arteries and urine
