Here's a breakdown of its components and functions:
* Kidneys: These bean-shaped organs filter waste products from the blood, such as urea, creatinine, and excess water.
* Ureters: These tubes transport urine from the kidneys to the bladder.
* Bladder: This sac stores urine until it's ready to be excreted.
* Urethra: This tube carries urine from the bladder out of the body.
Other parts of the excretory system include:
* Lungs: They remove carbon dioxide, a waste product of respiration.
* Skin: It excretes sweat, which contains excess salts and water.
* Liver: It filters harmful substances from the blood and produces bile, which helps in the digestion of fats.
The excretory system plays a vital role in maintaining the internal balance of the body (homeostasis) by removing waste products and regulating fluid levels.
