    The seminal vesicle is a pair of glands that open into the vas deferens and secrete some of the fluid that makes up semen. This fluid contains enzymes, protein, fructose, and vitamins to support the sperm. The fluid also has an alkaline pH to help neutralize the acidic environment of the vagina.

    Seminal vesicle head
    Correct!
    Wrong!

    This is the epididymis!

    The epididymis (say that three times fast!) is a curved tube on the back of the testis. It stores newly made sperm for about a week so it can mature to a point where it's able to fertilize an egg, at which point it passes through the tail of the epididymis into the vas deferens.

    Spermatic cord
    Correct
    Incorrect
    Efferent ductules
    Correct!
    Wrong!

    These are the efferent ductules!

    These are a group of 15–20 ducts that serve as a pathway for sperm between the testes and the epididymis. They help to reabsorb water from the luminal fluid (which carries sperm) to increase the concentration of sperm during ejaculation.

    These are the efferent ductules!

    These are the seminiferous tubules!

    The seminiferous tubules make up most of the testes. They are the actual site for the meiosis of cells into gametes, or the creation of sperm cells for sexual reproduction. These mature in the epididymis before they can fertilize an egg or ovum.

    Glans penis
    Correct!
    Wrong!

    This is the corpus cavernosum!

    The corpus cavernosa are two cylindrical bodies of tissue inside the entire length of the penis. They are spongy so when the nerve response of sexual arousal sends blood to the penis, the corpus cavernosa fills with blood. The sudden increase in blood volume causes stiffening and expanding of the penis, otherwise known as an erection!

    This is the corpus cavernosum!
