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: -The male external urethral orifice is the external opening or urinary meatus, normally located at the tip of the glans penis, at its junction with the frenular delta.
Detailed explanation-4: -The male urethra connects the urinary bladder to the penis. Once the bladder becomes full, urine flows through the urethra and leaves the body at the urethral meatus, which is located at tip of the penis. The urethra is more than just a urinary duct; it also serves as a conduit for semen and sperm during sexual acts.
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.
