PATHOLOGY

Detailed explanation-1: -Your urinary system is made up of the kidneys, the bladder, the ureters and the urethra. The urethra is the hollow tube that lets urine, a waste product, leave the body. The urethra can become infected or scarred.

Detailed explanation-2: -Urethra. This tube 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-3: -The part of the urethra that is closest to the bladder is called the proximal urethra. The part that is closest to where the urine leaves the body is called the distal urethra. The urethra is about 8 inches long in men and about 1½ inches long in women.
