Description: The urethra is the tube that transports urine from the bladder to the outside of the body. In humans, the urethra has different lengths and characteristics depending on sex. In males, the urethra is longer, measuring about 20 cm, and extends through the penis, also allowing the exit of semen. In females, the urethra is shorter, around 4 cm in length, and is located between the clitoris and the vagina. The urethra is composed of several layers of tissue, including an inner mucosa that helps protect it from infections and a muscular layer that allows control of urinary flow. Additionally, the urethra plays a crucial role in the urinary system’s function, as it is the last segment of the urinary tract, facilitating the excretion of liquid waste from the body. Its health is vital, as any obstruction or infection in the urethra can lead to serious complications, such as urinary tract infections or incontinence issues. Therefore, the urethra is not just a conduit but also an essential component in maintaining the body’s homeostasis, regulating fluid elimination and contributing to the body’s electrolyte balance.
