Excretory System Organs
Kidneys- Kidneys are bean-shaped structures located on either side of the backbone. In human each adult kidney size is 10-12 cm with a width of 5-7 cm and weighs around 120-170g and it have an inner concave structure.
Ureter - A pair of thin muscular tubes called the ureter. Ureter comes out of each kidney extending from the renal pelvis and it carries urine from the kidney to the urinary bladder.
Urinary Bladder - muscular sac-like structure which stores urine. The urinary bladder is emptied by the process of micturition.
Urethra- This tube comes out from the urinary bladder and helps to expel urine out of the body. It acts as the common route for sperms and urine in males.
