Male reproductive system diagram with labels.

Here are the functions of the labeled parts of the male reproductive system shown in the image: Urinary bladder: Stores urine before it is expelled from the body. Ureter: Carries urine from the kidneys to the urinary bladder. Seminal vesicle: Produces a fluid rich in fructose and other substances that nourish sperm and contribute to semen volume. Vas deferens: Transports mature sperm from the epididymis to the ejaculatory duct. Prostate gland: Secretes a milky, slightly acidic fluid that enhances sperm motility and viability. Bulbourethral gland (Cowper's gland): Produces a clear, lubricating fluid that neutralizes acidic urine residue in the urethra before ejaculation. Urethra: Serves as a passageway for both urine and semen to exit the body. Penis: The external organ that delivers semen into the female reproductive tract during sexual intercourse. Testis: Produces sperm and male sex hormones (e.g., testosterone). Epididymis: Stores and matures sperm, allowing them to gain motility. Foreskin: A fold of skin that covers the glans penis (if uncircumcised). Glans penis: The sensitive tip of the penis. That's 2 down. 3 left today — send the next one.
