Male/Female Reproductive System Test 9
what is a tubal ligation?
a medical sterilization procedure for women who are sure they don't want a future pregnancy, methods include banded, tied and cut, and cauterized, about 6 weeks recovery
testes
a pair of glands below and behind the penis, produce sperm and testosterone
fallopian tubes
a pair of tubes with fingerlike projections that draw in the ovum after being released from the ovary, the cilia within the tube and muscular contractions resulting from the movement of the egg create a forward movement, takes 2-4 days
vagina
birth canal, female sex organ, an elastic, muscular canal with a soft, flexible lining that provides lubrication and sensation that is 4-5 inches long, stretches for a baby or the penis
orgasm and ejaculation
once a male reaches puberty, he will have nocturnal emissions (wet dreams), when all male reproductive parts work together, he'll ejaculate semen
function of male
produce and store sperm, introduce sperm to female, produce hormones
pubic hair
responsible for keeping bacteria from entering the reproductive area
prostate cancer
second highest cause of men's cancer-related death because men usually ignore it, checked yearly at 55, runs in families so they start checking at 40 instead
what do the testes do in cold and warm?
shrivel up in cold and hang down in warm
perineum
skin between the vaginal opening and the anus, usually cut during birth so the baby can fit through the birth canal, called episiotomy
clitoris
small knob of tissue at the top of the reproductive area, rich supply of nerve endings and blood vessels, external organ for sexual arousal
semen
sperm, seminal fluid, and prostate fluid sperm is 5% of semen, the other fluids are 95%
primary male hormone, what other hormone?
testosterone, very little estrogen
ovaries
the female sex glands that store the ova and produce female sex hormones (estrogen and progesterone), produces hormones that trigger menstruation, also release at least one egg each month for possible fertilization, ovarian cancer
circumscision
the removal of the foreskin, removed for religious and health reasons, men have less infections when it is done, if it is not done, the penis must be cleaned properly to prevent infection
menstruation
the shedding of the uterine lining, the endometrium breaks down into blood, tissue, and fluid, this will then pass through the cervix and into the vagina
uterus
the womb, a hollow, pear-shaped, muscular organ that nourishes and protects a fertilized ovum until birth, if a fertilized egg implants itself in the lining of the uterus, a baby will grow, but if the egg isn't fertilized, it will leave the body through the vagina
seminiferous tubules
tiny tubules located in the testicles, responsible for sperm production
function of female
to have babies, produce hormones, storing eggs
inner/outer labia
two folds of skin that cover and protect the reproductive area, serves as a line of protection against pathogens (bacteria) from entering the body, have some nerve endings and serve as sexual arousal
where does a vasectomy occur?
vas deferens
secondary-sex characteristics of males
voice deepens, more muscle, bones grow, grow hair, able to sexually function
erection
when a man gets aroused sexually, blood flows into his penis at a faster rate than it flows out, causing it to get larger and harder
ovulation
when a mature ovum is released into the fallopian tube each month, takes an average of 2-4 days, controlled by the release of luteinizing hormone by the pituitary gland
what is an ectopic pregnancy?
when the fetus develops outside the uterus, usually in the fallopain tubes, it is a medical emergency, can cause the fallopain tube to rupture, 1/100 women run the risk of having an ectopic pregnancy
what is conception/fertilization?
when the sperm meets the egg
where must the sperm and the egg meet in order to make a baby?
fallopian tubes
fimbria
finger like projections near the ovary leading to the fallopian tubes, doesn't hold ovaries, wraps around them, when ovulation is about to occur, the sex hormones activate the fimbria, causing it to hit the ovary in a gentle, sweeping motion
cervical cancer
get a pap test once a year at either 18 or when a female becomes sexually active, runs in families
spontaneous erections
get them when not aroused, no reason for it, happens less and less frequently when a man gets older
cowper's gland
gland that releases the pre-ejaculatory fluid that cleanses the urethra so the sperm can survive their journey, fluid also helps to reduce acidity level in the female's vagina, sperm have been reported to be in this fluid
seminal vesicle
glands responsible for releasing a sugary like substance that nourishes the sperm on their journey, the substance allowed sperm to survive in a female's body for about 6-10 days (energy/food for sperm)
secondary-sex characteristics of female
grow breasts, grow hair, begin to menstruate, hips widen
foreskin
extra skin located at the tip of the penis
prostate
chestnut sized gland located just below the bladder, gland the releases an alkaline fluid that protects the sperm from the high acidic levels inside the female's body (protection for sperm)
hymen
circular fold of skin just inside the opening of the vagina, may be across the opening of the vagina, no known function, not present in all females, myth that if the females doesn't have the hymen intact that she isn't a virgin
epididymis
coiled segment of spermatic ducts that serves to store, mature, and transport sperm between the testes and the vas deferens
what occurs in the fallopian tubes?
conception/fertilization, ectopic pregnancy, and tubal ligation
gynecologist
doctor for the female reproductive system, should start going when 18 or sexually active
ova/ovum
eggs, needed to reproduce, females at birth have more than 400,000 immature ova in their ovaries
uterine lining
endometrium, blood and tissue that builds up every month on the inside of the uterus, waiting for a fertilized egg, forms placenta (filter for bad things), one of the few organs in the body that changes in size very month throughout fertile years, each month, as part of the menstrual cycle, the body prepares the endometrium to host an egg (embryo)
primary female hormones, what other hormone?
estrogen and progesterone, very little testosterone
what problems can the growth of the prostate cause?
it can interfere with functions of the body, causing bladder issues and issues with bowel movements
why do females get hips?
it makes it easier to have a baby
vas deferens
long J shaped tube that carries sperm from the epididymis to the seminal vesicles, passage way for sperm only
scrotum
loose, wrinkly pouch of skin that holds the testes behind and below the penis, keeps them at a temperature 2-4 degrees less than normal body temperature
cervix
lower portion of the uterus, approximately 2 inches long and tubular in shape, dilates during childbirth to allow for the passage of the baby, allows for the passage of menstrual fluid from the uterus, sperm need to travel through the cervix to reach the uterus
urethra
male - passageway for urine and semen female - passageway for urine only, separate from reproductive area
penis
male reproductive organ, grows during puberty
testicular cancer
most common cancer in men 15-35, usually diagnosed in mid-30s, signs include small, hard lump on testicle, feeling of heaviness in scrotum, ache in lower abdomen and groin, change in size or consistency
how many fallopain tubes does a female have? how many are needed to get pregnant?
most have 2, but you can get pregnant with 1, you can't get pregnant with 0 without a treatment
anus
opening of the rectum, removal of solid waste
rectum
place for solid waste build up and removal
