GENERAL HISTOLOGY

Detailed explanation-1: -Urethra. The tube that allows urine to pass outside the body. The brain signals the bladder muscles to tighten, which squeezes urine out of the bladder. At the same time, the brain signals the sphincter muscles to relax to let urine exit the bladder through the urethra.

Detailed explanation-2: -Urethra. A tube located at the bottom of the bladder that allows urine to exit the body during urination. All parts of the urinary tract-the kidneys, ureters, bladder, and urethra-must work together to urinate normally.

Detailed explanation-3: -(yoo-REE-thruh) The tube through which urine leaves the body. It empties urine from the bladder.

Detailed explanation-4: -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-5: -The ureter is a small tube, or duct, that connects the bladder and kidneys. Urine passes through the ureter from the kidneys to the bladder. The urethra is the tubular path that connects the bladder to the body’s exterior, allowing urine to exit the body.
