What is the Excretory System? All About the Urinary System

Discharge Is Not To Destroy.

The excretory system is very important to your body and consists of only a few parts. You need to get rid of liquids as well as removing solid residues from your body. The substance removed from the body as a result of this excretion Pee known as.

Urine is the result of the excretory system balancing the salt and water ratio in the body. We mentioned that the excretory system is small. Kidneys are the main organs of the excretory system. At the same time, the ureter, bladder and urethra are located in the excretory system. After the urine passes through the urethra, it leaves your body and the process is completed.

So What Does This System Do?

What do your kidneys do? The process of regulating fluid and salt levels in the body is also called osmoregulation. The kidneys act as a filter. Ultimately, all the blood in your body passes through your kidneys, so the kidneys filter the blood, pulling harmful molecules from the bloodstream, leaving molecules useful for your body.

The kidneys also play a key role in regulating your body’s fluid level. Let’s say you are in a desert and you are not able to consume too much water. Chemical signals are sent to the kidneys to reabsorb fluid in the body. As a result, your body produces less urine, so you lose less fluid. In a normal day, your body produces one and a half liters of water.

Interaction of Excretory System with Other Systems in the Body

It works with the excretory system, circulatory system and endocrine glands. Its connection with the circulatory system is quite clear. The blood circulating in the body passes through one of the two kidneys. Urea, uric acid and water are removed from the blood and a large amount of this water is added back to the blood.

The endocrine glands regulate the excretory system. It examines the fluids and compounds in the blood and creates the most suitable environment for the cells in your body. To do this, the function of the kidneys must be constantly changed. If you drink too much water, hormones responsible for more urine production are released. If you drink less water, your body produces less urine. Another situation where the kidneys are connected to the endocrine glands is the adrenal glands located on both kidneys. These glands are responsible for the release of adrenaline in the body.


Although there are many diseases that affect the urinary system, kidneys that do not function properly cause much greater problems. Blood pressure depends on the amount of fluid in the body, if the kidneys cannot function, blood pressure can rise to dangerous levels. As if this is not bad enough, urea accumulates in the tissues and poisons your cells as it cannot be excreted.

Individuals whose kidneys are not working properly usually dialysis it has to go through a process called. In this process, they are connected to a machine that performs the function of the kidneys. Acting as an artificial kidney, this machine tries to regulate ion and water levels in the blood. Many dialysis patients are currently waiting for a kidney transplant.
