What is the primary function of the urethra?

• A. To transport urine outside the body
• B. To filter blood
• C. To store urine
• D. To produce urine

Answer: (A)

The primary function of the urethra is to transport urine outside the body. This narrow tube connects the bladder, where urine is stored, to the external opening, allowing for the excretion of urine during the process of urination. This function is essential for maintaining the body's fluid balance and eliminating waste products. In contrast, filtering blood is performed by the kidneys, which remove waste and excess substances to form urine. The storage of urine is the role of the bladder, which holds the urine until it is ready to be expelled. Urine production also takes place in the kidneys, where blood is processed to create urine. Thus, the urethra's specific and crucial role in the urinary system is to serve as the pathway for urine's exit from the body.
