Water loss, chemical re-absorption, protection from infection, and several other important process are directly related to this system.
Organs and body areas of this system include:
Humans produce around 1.5 liters of urine in a 24-hour period.
The kidney concentrates the urine by regulating electrolytes and remove
urea from the blood and other wastes.
Urea is an organic compound that was discovered in 1773.
This compound is soluble in water and is essentially a waste product.
Production of urea occurs in the liver and is the result of the breakdown of some amino acids.
The bladder is an organ that is hallow.
It is layered similar to a balloon with several muscles that make up this organ.
The muscle is a smooth muscle
Smooth muscle allows the bladder to enlarge when it becomes full and small when empty.
Overall the bladder can hold 400-620 ml but the maximum is twice this amount if outflow is obstructed.
This is the endpoint of the urinary system.
Urine and other wastes begin in the kidney and then to the bladder and finally through the urethra and out the the vaginal opening.
This tube connects the bladder to the outside of the body.
Control of excretion of urine is through the urethral sphincter
