Water loss, chemical re-absorption, protection from infection, and several other important process are directly related to this system.
Humans produce around 1.5 liters of urine in a 24-hour period.
Organs and body areas of this system include:
– 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.
– The bladder lies just behind the Uterus and near the Vagina.
– 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
