What is the Excretory System?

It's a great question to ask, right? The excretory system helps get rid of waste products that are are not useful in the body. Some waste products are even so toxic that the body needs a system to eliminate them.

 

The most important organs of the excretory system?

The most important organs of the excretory system are the kidneys. The kidneys are placed on either side of the spinal column near the lower back. The kidneys are bean-shaped and they have an important job. They are responsible for removing wastes from the blood and they also keep your blood pressure in check and help with the making of red blood cells. When your body gets ready to pass waste products, it goes through the kidneys and mixes with water and urine. Then, the waste travels into the bladder through tubes. These tubes are called Ureters. Now, the bladder holds all of that urine until it feels so full that you need to get rid of it. That's called urination. When this happens, a tube called the Urethra takes the urine to the outside of the body.

 

Did you know that each kidney is about the size of a clenched fist?

Did you know that the tube called the ureter leaves each kidney, carrying urine to the urinary bladder?

The urinary bladder is a bag-like organ that keeps urine stored before being excreted.

The kidneys take all of the toxic waste that the body wants to get rid of.
