Video: How does our kidney work?

The urinary system in human beings consists of two kidneys ureters, urinary and urethra. The reddish brown, bean shaped kidneys are situated at the back of the abdominal cavity, one on each side of the vertebral column.

The kidneys are made up of large number of coated tube-shaped filters called nephrons. They carry nitrogenous waste material and excess water from the blood and from urine which passes via ureters to the urinary bladder.

When the bladder gets filled with urine, it is exerted through the urethra by contraction of muscles around the urinary bladder. Waste material removal is important for all living organisms. Normal kidney function is essential for a good health.
