Science - Reproductive Flashcards
What is a scrotum?
External sack that in most mammals contains the testes
what are the testes
organ that produces sperm
what is a sperm duct
carries sperm from testes to penis
what is a ureter
tube that carries urine from kidneys to bladder
what is a urethra
tube that carries urine from bladder to out of the body
what is a urethra
tube that carries urine from bladder to out of the body
what is a seminal vesicle
makes semen
penis
an external male reproductive organ
what is a ovary
female gland in which the eggs form
what is a fallopian tube
tube that connects ovary to uterus that carries the egg
what is a uterus
musical bag where the baby grows
what is a cervix
small narrow canal that conects the uterus to the vagina
what is a vagina
muscular organ of the female system
what is a endometrium
lining of the uterus that sheds every month and rebuilds
What’s the pattern of plantation
zygote (implantation)
embryo (becomes surrounded by membrane called amnion)
amnion fillies with amniotic fluid
foetus
4 points on umbilical cord
The baby’s blood passes through the umbilical cord and attaches to the lining of the uterus
8 weeks - foetus
the umbilical cord connects baby to placenta at navel
placenta 2 points
organ fully develops week 12
passes substances (nutrients) from mother and baby
Labour
The birth canal widens, the amnion bursts and contractions of the muscle begins
Birth
contractions continue helping to push the baby out of the birth canal
Removal of placenta
after birth
What is puberty?
Puberty is when humans develop sexual characteristics which distinguish females from males and vice versa.
what is ovulation
Ovulation is the time during the menstrual cycle when an egg is released from the ovary into the fallopian tube
What is contraception
is the deliberate use of artificial methods to prevent pregnancy
What is natural contraception
The abstinence from sexual intercourse
What is mechanical contraception
A condom : a thing rubber sheath that covers the penis and prevent sperm from entering into the vagina
diaphragm: a dome-shaped rubber cat that fits over the cervix jd prevents sperm from entering the uterus
chemical contraception
contraception pill: contains oestrogen or progesterone and prevents ovulation
Surgical contraception
Tubal ligation: fallopian tubes are cut and sealed which prevents fertilisation
vasectomy: the cutting or tying off of the sperm ducts there will be no sperm in the semen
