ANATOMY

Detailed explanation-1: -Urine leaves your body through a hole at the end of your urethra. That hole from the inside to the outside is called the urethral meatus. (The term ‘meatus’ refers to any opening from the inside to the outside.)

Detailed explanation-2: -Bladder emptying is known as urination. 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: -The urethra is a part of the renal system. The kidneys, ureters, and bladder are also part of this system. The renal system is responsible for producing, storing, and eliminating liquid waste in the form of urine. The urethra transports urine that’s stored in the bladder out of the body.

Detailed explanation-4: -Two of the openings are from the ureters and form the base of the trigone. Small flaps of mucosa cover these openings and act as valves that allow urine to enter the bladder but prevent it from backing up from the bladder into the ureters. The third opening, at the apex of the trigone, is the opening into the urethra.
