Everyday, the body takes in food and liquids. However, not all of these are absorbed by the body. The materials not utilized by the body are eliminated. When wastes are not removed from the body, they can eventually poison the body. That is why your body has the systems that aid in the excretion of these wastes.
Excretion is the process by which waste materials are removed from the body. Excess water and salt are also eliminated through pores in the skin. The system responsible fot excreting most of the liquid wastes from the body, the urinary system. The main parts of the urinary system are the kidneys,ureters,urinarybladder,and urethra. The liquid waste of the body filtered through this system is called urine.
What are the parts and functions of the urinary system?
Kidneys
The kidneys are two bean-shaped organs on each side of the body. They are the main organs of the urinary system. The kidneys filter and clean the blood to remove waste substance and ensure that only useful substances stay in the blood that circulates throughout the body. The kidneys remove excess water, salts, urea, and other wastes from the blood. Each kidney has thousands of filters called nephronsthat filter the blood about 300 times a day.
The blood is carried to the kidneys, which filters excess water and waste from it. Then, the blood goes back to the heart and then to the lungs to receive oxygen. The blood then returns to the heart to be pumped and distributed to the different parts of the body.
Ureters
The urine flows out from the kidneys to the urinary bladder through the two ureters. The smooth muscles of the ureters move by peristalsis to move the urine towards the urinary bladder.
Urinary Bladder
The urinary bladder is a hollow muscular organ where urine is temporarily stored. The muscles of the bladder contracts to push the urine out of the body.
Urethra
Urine is emptied from the bladder and leaves the body through the urethra. The urethra is a tube at the bottom of the bladder. The lenght of the urethra varies in males and females. The urethra has a sphinctermuscle which serves as a valvelike structure to help regulate the outflow of urine.
Urination is the process of eliminating urine. Holding back urination can be harmful. One should urinate as the need arises. The amount of urine that passes through the body varies according to the amount of fluid a person drinks and the amount lost in the form of perspiration.
On the average, however, the urine output may be about 1.4 liters each day. The nature of urine varies too. Its color and odor may vary according to the intake amount of water or drinks. The turbidity of urine depends on the amount of salts in the diet.
