Organs of the urinary system
How the urinary system works
The kidneys remove waste chemicals like urea from the blood. The blood containing chemical wastes enters the kidneys through the renal arteries. The blood is processed through the nephron to make urine. Urine is yellow water with waste chemicals in it.
The urinary bladder is a soft container. It has muscles. Its muscles can make it bigger or smaller. It becomes bigger when it is full of urine. At such times we feel it, and we have to pee.
There is one tube that goes out of the urinary bladder. This tube lets the urine out of the body. This tube is the urethra.
