Reproductive System Flashcards
Scrotum
Abdominal sac
Keeps the sperm-forming cells cool enough to function normally
Testes
Male gonads
Epididymis
Transports sperm cells from epididymis to urethra to be expelled
Ejaculation
The expulsion of the sperm-containing fluid from the penis
Vans deferens
Muscular contractions propel the sperm from the epididymis through this other duct
Ejaculatory duct
Conveys sperm from the other testis
Urethra
Conveys both urine and sperm out through the penis
3 sets of glands in the male reproductive system
- ) Seminal vesicles
- ) prostate gland
- ) bulbourethral glands
Seminal vesicles
Secrete a thick fluid (contains fructose) which provides most of the energy used by the sperm
Secretes:
- fructose
- mucus
- sperm cells
- prostate fluid
Corpus iuteum
Releases hormones
Endometrium
Lining of the uterus
Where implantation takes place
Functions of the vagina
- ) birth canal
- ) receptical for semen
- ) receives male copulatory organ during sexual intercourse
- ) output for the release of menstrual tissue
Contraception
Prevents pregnancy
Protection
Prevents disease
3 parts of clitoris
Shaft
Glans
Prepuce
Shaft
Contains erectile tissue
Glans
Head of clitoris
Prepuce
Covers end of clitoris
Bartholins gland
(Female)
Produces lubricant
Neutralizes pH of vagina
Labia minora
Prevents outside particulate material from entering the vagina
Labia majora
Absorption from external trauma
Seminiferous tubules
Site of spermatogenesis
Increases surface area - more sperm in compact testes
Acrosome
Blasts hole in membrane of ova
Polyspermy
2 sperm enter at the same time
