• amniotic fluid, protects the developing foetus, supports, cushions, absorbs shock, regulates temperature
• ovary stores ovules
• ovule, female sex cell, formed after fertilisation
• cervix ring of muscles between uterus and vagina, dilates during birth
• foreskin thin layer of skin, covers end of penis
• sperm duct carries sperm from testes- penis
• penis deposits semen in vagina during sex
• vagina receives semen from penis during sex
• scrotum holds testes away from the body
• uretha carries sperm through the penis
• bladder stores urine, excretory system
• progesterone released ovaries, maintains thickened lining of the uterus incase implantation of a fertilised egg. inhibits production of LH and FSH
• oestrogen SSC- start of menstrual cycle, hips widen and breasts develop, change in distribution of fat
• glands produce and released different hormones
• uterus where the foetus develops during pregnancy
• ovary produces egg cells
• oviduct carries the egg away from the ovary
• oestrogen- released in the ovaries, stimulates lining of uterus to repair and thicken, stimulates release of LH, development of secondary sex characteristics
• LH, released in the pituitary gland, stimulates development of egg, stimulates release of oestrogen
• placenta organ that develops during pregnancy, supplies (glucose, oxygen, antibodies) removes (co2 and urea)
• FSH released in the pituitary gland, causes follicle to burst and release an egg, ovulation
