PATHOLOGY

Detailed explanation-1: -Urinary bladder is a small bag-like structure which receives urine from both the ureters. Urinary bladder stores the urine till it is released through the urethra.

Detailed explanation-2: -The bladder is a hollow, sac-like organ that stores urine. When the bladder is about half full, it sends a nerve impulse to a sphincter to relax and let urine flow out of the bladder and into the urethra. The urethra is a muscular tube that carries urine out of the body.

Detailed explanation-3: -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.
