Order of sperm cell traveling from male body to female body
testes, sperm duct, prostate gland, urethra, penis --> vagina, cervix, uterus, oviduct
female sex hormones
male sex hormones
role of oestrogen in developing characteristics
change in behaviour, stimulates development of secondary sex characteristics, breast, hips, vagina and hair develop/grow
role of testosterone in developing characteristics
change in behaviour, stimulates development of secondary sex characteristics, facial hair, chest, testes and penis develop/grow
oestrogen in menstrual cycle
repairs lining of the uterus
progesterone in menstrual cycle
keeps the lining of the uterus ready for implantation
FSH in menstrual cycle
stimulates follicular growth (sac around egg cell) and estrogen secretion
LH in menstrual cycle
stimulates ovulation to occur and development of corpus letuem in the remains of the follicle
define ejaculation
the release of sperm from the testes after stimulation
define copulation
sexual intercourse
define conception
conceiving a child
define fertilization
the process of combining the sperm cell with the egg cell
define ovulation
release of the egg from the ovary
difference in egg cell and sperm cell
egg cell is singular, while sperm is more.

hormonal or non-hormonal
example of natural contraceptive
timing or calendar method

a fertalized egg
define embryo
early stages of development in the womb
define puberty
process of physical changes through which a child's body matures into an adult body capable of sexual reproduction
pituitary gland
part of the brain controlling growth and development
define implantation
the attachment of the fertilized egg to the wall of the uterus
corpus luteum
A sac for the egg cell which will eventually shrink and be absorbed
the sac that releases an egg during ovulation
menstrual cycle phases
menstruation, the follicular phase, ovulation and luteal phase.
umbilical vein
carrys oxygenated blood from the placenta to the fetus
umbilical artery
carry deoxygenated blood from fetus to the placenta
male structure
bladder, seminal vesicles, testis, scrotum, urethra, prostate gland, vas deferens and penis
female structure
vagina, cervix, uterus, fallopian tubes, ovaries
body temperature during menstrual cycle
increases at ovulation
LH during menstrual cycle

FSH during menstrual cycle
increases at ovulation
progesterone during menstrual cycle
curves after ovulation
estrogen during menstrual cycle
increases before ovulation, drops and curves after ovulation
negative feedback results in
hormones decreasing
positive feedback results in
hormones increasing
male reproductive cell
sperm cells
female reproductive cell
egg cell
primary sex organs
testes and ovaries, which are stimulated by the pituitary glands during puberty
