ANATOMY

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: -The bladder is a hollow, muscular sac that receives the urine from the ureters and stores it until it is ready to be emptied from the body.

Detailed explanation-3: -bladder: a sac that holds pee until it’s time to go to the bathroom. urethra: the tube that carries urine from the bladder out of the body when you pee.

Detailed explanation-4: -The bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear. Urine is made in the kidneys and travels down two tubes called ureters to the bladder. The bladder stores urine, allowing urination to be infrequent and controlled.

Detailed explanation-5: -The external sphincter muscles surround the internal sphincter and provide extra pressure to keep the urethra closed. You can consciously squeeze the external sphincter and the pelvic floor muscles to keep urine from leaking out.
