reproductive systems

males and females both have

• a pair of gonads responsible for producing gametes (testes in males, ovaries in females)

• network of ducts connecting from the gonads and other body regions to the external environment

• both produce hormones of maturation and maintince of resporductive system

male repordutive system purpose

• produce and store sperm

• transfer sperm for fertilisaltion of an ovu in female reporductive system

female reporductive system purpose

• produce ova

• provide a site for fertilisation

• support pregnancy and childbirth

sperm formation

testes

• 2 testicles that produce sperm via spermtogensis

seminifours tubles

• where spermtogensis occurs

• has internesital cell to produce testosterone

scrotum

• sac holding testcicles outside abdominal cavity

• if abdominal cavity gets to hot, sperm cannot produce properly as it has na optimal temp of 32-35 degrees.

sperm transfer and storage

epdidmysis

• located on top of testes and is involved in sperm maturation and storage

vas deferes

• 2 stright musculars tubes going from epdidymis to urethra

• transport mature sperm during ejaculation

semen

• fluid aiding in transportation of sperm

urethra

• duct connecting bladder and vas deferens

• transport semen and urine outside the body

penis

• transport sperm into the vagina during sexual intercourse

• erectile tissue has spongy-like spaces that fill with blood during arousal

• stiffens to be introduced into vagina

acessory glands

seminal vesicles

• located behind the bladder

• secrete a thick, sugar-rsh (fructuose), clear fluid that makes a large volume of semen

boulthermaw/corpaws duct

• located behind porstate gland

• secretes a thick clear fluid to help with the lubrication of the sperm and semen

prostate gland

• secretes a thick, white fluid helping to nutrilise acid in females body to protect sperm cells

• also helps in acitivating sperm motility

ovaries

• 2 ovaries to produce an ovum via oogenesis

• produces oestrogen and progesterone

• contains small sacs called follciles that surround and nourish and oocyte during oogenisis

• fimbraie are small fingerlike structures that gently push ovum to the uterine tube

• fimbraise are found in the opening of the ovary

fallopian tubes

• 2 ducts extending from each ovary

• lined with cilia to move ovum to uterus along with uterine contractions along the myometrium

• location of fertilisation and zygote formation

uterus/womb

• hollow pear shaped organs

• smooth muscular walls (mymetrium) allowing for contraction during mensturstion + childbirth

endometrium

• soft mucus membrane, lining msucular wall and is rich in blood vessels

• where the embryo implants itself

• if there is no ferilisation, ovum degnerates along with endometrium via mensturation

cervix

• neck of uterus

• is the canal to the external body

• recives penis during sexual intercourse and dilates for baby to pass through during labour

vagina

• opens to exterior = vulva

• vulva contains liberia minora, majora and clitoris
