Detailed explanation-1: -From the calyxes, pee travels out of the kidneys through the ureters (pronounced: YUR-uh-ters) to be stored in the bladder (a muscular sac in the lower belly). When a person urinates, the pee exits the bladder and goes out of the body through the urethra (pronounced: yoo-REE-thruh), another tube-like structure.
Detailed explanation-2: -Bladder. This triangle-shaped, hollow organ is located in the lower abdomen. It is held in place by ligaments that are attached to other organs and the pelvic bones. The bladder’s walls relax and expand to store urine, and contract and flatten to empty urine through the urethra.
Detailed explanation-3: -Ureter is the duct through which urine passes from the kidney to the bladder. Urine is excreted through the urethra.
Detailed explanation-4: -The main excretory organ of the human body is kidneys. There are one pair of kidneys which filter blood and remove waste products in the form of urine.
Detailed explanation-5: -Urine is made in the renal tubules and collects in the renal pelvis of each kidney. The urine flows from the kidneys through the ureters to the bladder.
