human reproduction test

puberty

a period of rapid growth in the reproductive system, it becomes fully functional (woman start before men)

sprem

male gamete

egg

female gamete

testies

what sperm is produced, two, produce in cool conditions

ovaries

where eggs are produced

testosterone

primary male sex hormone

scrotum

where testes are, thin external sac of skin and muscle tissue

seminiferous tubules

hundreds of tightly coiled tubes that make up testes where sperm cells are produced

epididymis

where the sperm is stored and matures, stays around 2 weeks

vas deferens

tube that connects epididymis to urethra, transports and carries sperm

urethra

sperm stops here and leave body through the tip of urethra

semen

fluid that contains sperm mixed with these various secretions

ejaculation

the ejection of sperm out of the penis through the urethra

seminal vesicles

two vesicles that lie between the bladder and the rectum and provide a fluid rich in sugars that sperm use for energy

prostate gland

located below the bladder and secrets an alkaline fluid that helps to balance acidic pH found in female reproduction system

bulbourethral gland

these secrete fluid that neutralizes traces of acidic urine in the urethra

ovum

a mature egg

fallopian tube

a passageway through which the ovum moves from the ovary to the uterus

vulva

the external structure of the female reproduction system

vagina

a muscular tube that leads from the vulva to the cervix; where sperm are appointed during sexual intercourse

uterus

a hollow

cervix

the lower end of the uterus; has a ring of muscle

menstrual cycle

the monthly cycle of changes that occur in the female reproductive system

follicle stimulating hormone

a hormone secreted by the anterior pituitary gland that promotes the formation of ova or sperm.

Luterinizing hormone

completes process of follicle development in ovary; message to release the egg

estrogen

A sex hormone, secreted in greater amounts by females than by males; tells the uterus to rebuild its lining

Progesterone

A hormone produced by the ovaries which acts with estrogen to bring about the menstral cycle.

implantation

occurs in the uterus and the embryonic will attach to the walls in egg is fertilized in the fallopian tubes

fertilization

if a sperm is present in the fallopian tube when the mature egg is traveling the egg can become fertilized

4 phases of menstrual cycle

follicular phase, ovulation, luteal phase, menstruation

4 hormones in the menstrual cycle

follicle stimulating hormone, luteinizing hormone, estrogen, progesterone

mentrual cycle

series of changes that occur every 28 days to prepare for a possilbe pregnancy

ovaries

where are eggs produced

testies, scrotum, epididymis

where sperm is created, stored and matured

23 chromosomes each

make up of a healthy sperm and egg cell

female gametes and process

eggs, in ovaries

male gametes and process

sperm, testies

corpus luetum

structure that forms after and egg has been released. It secretes progesterone

zygote

fertilized egg

blastocyst

A fluid-filled sphere formed about 5 days after fertilization of an ovum that is made up of an outer ring of cells and inner cell mass

embryo

the developing human organism from about 2 weeks after fertilization through the second month

fetus

the developing human organism from 9 weeks after conception to birth

gestation

9 month period of human development

placenta

A structure that allows an embryo to be nourished with the mother's blood supply
