Detailed explanation-1: -The final passageway for the flow of urine is the urethra, a thin-walled tube that conveys urine from the floor of the urinary bladder to the outside. The opening to the outside is the external urethral orifice. The mucosal lining of the urethra is transitional epithelium.
Detailed explanation-2: -Humans have two kidneys, each of which passes urine to the bladder by a tube called the ureter.
Detailed explanation-3: -The external urethral orifice is the external opening (or meatus) of the urethra. It is where urine exits in both males and females. In males, it is also where the semen is ejected during ejaculation. The male external urethral orifice is located on the glans penis, at the tip, at the junction with the ferenular delta.
