Know Your Excretory System | Signs of Health
Discover how your kidneys, bladder, skin and lungs work together to remove waste and keep your body healthy — explained in ISL!
Imagine never taking out the garbage from your house. It would keep piling up and eventually become unhealthy. Your body faces a similar problem, but thankfully, it has its own smart cleaning system. The excretory system constantly removes waste from your body and helps keep you healthy.
The journey begins in your blood. When your body uses food for energy, it produces waste products that travel through the bloodstream. This is where your two kidneys step in. Located on either side of your lower back, the kidneys act like smart filters. They remove waste, extra salts and extra water from your blood.
Inside each kidney are millions of tiny filtering units. They separate the useful substances your body needs from the waste it does not. The useful substances return to your blood, while the waste and extra water become urine.
The urine then travels through two thin tubes called ureters, which carry it from the kidneys to the bladder. The bladder works like a storage tank, holding urine until it is time to use the toilet. As the bladder fills, your brain receives a signal telling you that you need to go. The urine then leaves your body through a tube called the urethra.
But your kidneys aren't the only organs involved in removing waste. Your skin helps through sweating, which removes extra water and small amounts of waste. Your lungs also play a role by removing carbon dioxide when you breathe out.
If the excretory system does not work properly, waste can build up in the body. This may cause tiredness, weakness, swelling or difficulty passing urine. That is why taking care of your excretory system is important.
You can support your kidneys and overall health by drinking enough water, eating a balanced diet, staying active, exercising regularly and avoiding holding your urine for too long. If you experience pain or burning while passing urine, it is important to consult a doctor.
Remember, your body is constantly cleaning itself, even when you don't notice it. Your kidneys, ureters, bladder, urethra, skin and lungs all work together to remove waste and keep your body healthy.
