What are Kidneys?
The kidneys are bean-shaped excretory organs in vertebrates.
Each kidney contains about 1,000,000 to 1,300,000 nephrons, which is the
basic functioning component of the kidney, and are specialized in such
a way that it can move material back and forth between blood plasma and
urine in order to conserve essential materials while still eliminating
The kidney filters out the extra fluid and waste products, creating
urine. The urine passes through the ureters into the bladder. The clean
blood flows back to other parts of your body.
Main kidney functions:
- remove waste products through urine
- control the amount of water in your body
- maintain the chemical balance of the body
- play a role in blood pressure regulation
- make hormones; these hormones help to control blood pressure, make
blood cells, and maintain bones
