GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -(yoo-REE-thruh) The tube through which urine leaves the body. It empties urine from the bladder.

Detailed explanation-3: -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.

Detailed explanation-4: -Urination, also sometimes referred to as micturition, is the ejection of urine from the urinary bladder through the urethra to the outside of the body.

Detailed explanation-5: -Anatomy of the distal and proximal urethra. Urine flows out of the bladder and leaves the body through the urethra. 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.
