Excretory system in humans
The excretory system in human beings includes a pair of kidneys, a pair of ureters, a urinary bladder, and a urethra. This is also known as the urinary system.
*The kidneys are located in the abdomen, one on either side of the backbone. They act as excretory organs and also control the balance of water and mineral ions in the body.
*From each kidney, a ureter arises which opens into the urinary bladder.
*The urethra passes urine to the outside of the body. The urethra emerges through the penis in males and close to the vagina in females.
Excretory pathway in kidney – Blood is carried by the renal artery to the nephron from thereto renal pyramid leading to pelvis to the ureter, then to the urinary bladder and finally to the urethra which passes it to outside.
