Bio 164: Urogential anatomy

the sac that holds the testes

the organs that make sperm cells

the series of hollow tubes that stores mature sperm cells

the tubes sperm cells travel through during ejaculation, before the urethra. The sperm cells are suspended in salt water solution.

this gland secretes a sticky yellowish/whitish fluid which makes up about 60% of semen. The fluid enters the urethra via the ejaculatory ducts

transports urine from the bladder the outside of the body, and also transport semen from the reproductive organs to the outside of the body

small paired tubes that carry sperm from the vas deferens and fluid from seminal vesicles into the urethra, they pass through the prostate gland.

during arousal this gland secretes a small amount of slippery fluid into the urethra to neutralize any acidic urine and lubricate the glands

this gland secretes a thin, milky white fluid, which makes up about 30% of semen. This fluid enters the urethra as it passes through the prostate.

made of 3 spongy tissue layers

• the paired corpora cavernosa

• single corpus spongiosum

sometimes called the head, covered by a layer of skin called the foreskin.

the hollow sac that stores the urine formed in the kidney

made up from ductus deferens, the testicular artery, and testicular veins. Travels from the testis of the scrotum, through the inguinal canal and into the abdominal cavity

the organ that makes oocytes (egg cells)

transports ovulated oocytes from the ovary to the uterus

a hollow structure that contains a thick layer of smooth muscle, and endometrium. Located in the pelvic cavity, but will expand into the abdominal cavity during pregnancy

smooth muscle in the uterus

tissue lining the smooth muscle in the uterus

the dome shaped superior aspect of the uterus

the narrow muscular opening to the uterus containing a sticky mucus to prevent the passage of bacteria and pathogens

the “ligament” that is a fold of peritoneum that covers and supports the uterus

the hollow muscular tube that connects the uterus to the outside world, the external opening the vaginal canal is called the vaginal orifice

the walls of the vaginal canal secrete a fluid that lubricates the canal and orifice during sexual arousal

two thin folds of skin that enclose the vaginal orifice and urethral opening

two thicker folds of skin that enclose the labia minor and the glans of the clitoris

structure containing a spongy erectile tissue
