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: -The urinary meatus, also known as the external urethral orifice, is the opening or meatus of the urethra. It is the point where urine exits the urethra in males and in females, and also where semen exits the urethra in males.

Detailed explanation-3: -It opens externally through the urethral meatus (external urethral orifice), which is a vertical slit-like opening slightly behind the tip of the penis.

Detailed explanation-4: -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.

Detailed explanation-5: -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.
