The Excretory System
Functions
The Excretory System filters the blood through the kidneys. It then gets rid of the wastes in the form of urine. It also keeps the balance between water, irons, pH, calcium, red blood cells, and blood pressure.
The Main Parts
The Excretory System consists mainly of the kidneys, urinary bladder, ureters, and urethra. These all have a role in ridding the body of wastes, filtering your blood, and keeping the balance of water and salts.
Working With Other Body Systems
Our body systems have different functions, and use them to work together to keep our body alive and healthy. Two of the many body systems the Excretory System works with are the Circulatory and Muscular Systems. The Excretory System works with the Circulatory by removing the wastes from the blood that got it from cells and filtering the blood through the kidneys. The Muscular System works with the Excretory by providing the smooth muscles that make up the internal organs in the Excretory System.
Medical Conditions
A common medical condition of the Excretory System is a Urinary Tract Infection, which is more common in women. It occurs when bacteria enters the urinary tract, and can affect the kidneys, urethra, or bladder.
Another condition is Interstitial Cystitis, and is more common in women. It cause bladder pressure and pain and pelvic pain.
There is also Kidney Failure, where your kidney is unable to filter your blood. If you don't have your second kidney, you will need a kidney transplant.
