The excretory system is responsible for removing waste products from the body. It primarily includes organs such as the kidneys, ureters, bladder, and urethra. The kidneys filter blood to produce urine, which contains waste substances and excess water. Urine travels from the kidneys through the ureters to the bladder, where it is stored until it is expelled from the body through the urethra. This process helps maintain the body's balance of fluids and electrolytes, ensuring overall health and proper functioning.
