human sexuality (reproductive systems)

what are the parts of the male reproductive system?

scrotum, testicle/testis, epididymis, vas deferens, seminal vesicles, prostate, cowpers gland, urethra, penis, glans, urinary bladder, foreskin, and anus.

define scrotum

the wrinkly sac of skin, sparsely covered with hair, that holds the testicles.

define testicle/testis

the organ located behind the penis that produces sperm.

define epididymis

a long, tightly coiled duct that carries sperm from seminiferous tubules of the testes to the vas deferens.

define vas deferens

the tube that transports sperm from the epididymis from each testicle to the urethra in the prostate gland. (also called to as ductus deferens).

define seminal vesicles

the two sac-like glands at the base of the bladder and connected to the prostate gland that provide nutrients for the semen.

define prostate

a walnut-sized gland that surrounds the neck of the bladder and the urethra. this gland helps produce milky semen necessary for carrying sperm.

define cowpers gland

a pair of small glands at the base of the penis that secretes seminal fluid.

define urethra

a tube leading from the bladder that carries urine through the penis to the opening at the tip of the glans. semen also passes through this tube.

define penis

the sex organ of generation.

define glans

the head of penis.

define urinary bladder

the organs that holds urine excreted by the kidneys.

define foreskin

the loose fold of skin that covers the end of the penis. foreskin is removed during circumsion.

define anus

the outlet of the rectum lying in the fold between the buttocks. the opening at the end of the anal canal.

what is circumcision

the operation to remove the foreskin of the penis.

what are the parts of the female reproductive system?

vulva, ovaries, fallopian tube(oviduct), uterus, endometrium, cervix, vagina, ureter, urinary bladder, urethra, rectum, and anus.

define vulva

the “outside” or external sex organs.

define ovaries

the pair of organs that store and release egg cells and produce estrogen.

define fallopian tube(oviduct)

one of a pair of ducts opening at one end into the uterus and at the other end into the peritoneal cavity, over the ovary. each tube serves as a passage through which an ovum is carried to the uterus from the ovary.

define uterus

a pear-shaped hollow organ with the muscular walls where a fertilized egg becomes embedded and the fetus develops.

define endometrium

the inner lining of the uterus, which is partially shed during menstruation.

define cervix

the part of the uterus that protrudes into the cavity of the vagina.

define vagina

a hallow, muscular, tunnel-like structure that forms the passageway between the cervix and vulva.

define ureter

one pair of tubes that carrie urine from the kidneys into the urinary bladder.

define urinary bladder

the organ that holds urine excreted by kidneys.

define urethra

a tube leading from the bladder that carries urine out of the body. its opening lies in vulva.

define rectum

the lower part of the large intestine, between the sigmoid colon and the anal canal.

define anus

the outlet of the rectum lying in the fold between the buttocks. the opening at the end of the anal canal.
