Reproductive System - Naidelin Alvarez Period 5 - Coggle Diagram
Reproductive System - Naidelin Alvarez Period 5
Functions
Female
production of female gamete (egg)
preparation for support developing embryo during pregnancy
provide space and good conditions for a baby to develop
secreting sex hormones
providing a site for fertilization, giving birth and breastfeeding a baby
Male
produce & disseminate a large quantity of sperm
transport semen
discharge sperm into females
Anatomy of Male
testicles
primary male sex organ
tightly coiled structures
sperm travels through to epididymis
epididymis
expels sperm with contraction of muscles
found on the superior part of the testis
mature & store sperm cells
urethra
organ of both female and male
carries both sperm & urine
sperm enters from the ejaculatory duct
vas deferens
moves sperm by peristalsis
pass through the the inguinal canal
carries sperm from epididymis to the ejaculatory duct
penis
distal portion of urethra passes
delivers sperm into female reproductive system
also delivers urine to exterior
Anatomy of Female
cervix
narrow outlet
protrudes into the vagina or opening into the uterus
keeps bacteria out of uterus
discharge to clean vagina
protects pregnancy
uterus
receive a fertilized egg
retain/nourish the fertilized egg
hollow organ
fallopian tubes
receive the ovulated cycle
provide a site for fertilization
receive the oocyte the ovary
Ovaries
female gonads
primary female reproductive organs
secrete hormones
protect eggs female born with
hormones
Female
progesterone
regulates the monthly mentrual cycle
levels rise in the second half of mentrual cycle
helps prepare women's body for conception and pregnancy
thickening ht lining of the uterus each month
estrogen
helps develop & maintain both reproductive systems
develop breast and pubic hair
contributes to cognitive health
function of cardiovascular system
Male
FSH
follicle-stimulating hormone
pubertal development
controls the production of sperm
levels increase once men get older
LH
luteinizing hormone
helps produce sperm
levels rise with years of puberty
causes the testicles to make testosterone
Female hormonal cycle
Ovarian cycle
ovulation
triggered by sudden spike increase in LH
stimulating the pituitary glanf
graafin follicle releases the oocyte
slight rise in progesterone
luteal phase
follicle expels the oocyte
the empty shell becomes corpus lutuem
progesterone, some estrogen & inhibit which suppresses FSH
follicular phase
follicular cells secrete estrogen
graafin follicle will eventually become the egg that is released
HSG causes follicular cells develop into primary follicle
Menstrual cycle
proliferative cycle
causing it to double in thickness
thickening of endometrium allows ovulated egg to be caught implantation
estrogen stimulates growth of blood vessels of the endometrium
secretory phase
uterine glands enlarge & secrete nutrients to sustain the embryo until implantation occurs
progesterone levels drop following decline in LH leading into menstrual cycle bleeding for the next time
uterus becomes ready fro pregnancy
menstruation
constrict, cells become ischemia & die
sloughed off or shed
decline of estrogen & progesterone cause the spinal arteries
bleeding last fro 3-5 dyas
Disorders
HIV
virus that attacks the body's immune system
if not treated it can lead to aids
HIV once it hits its for life
transmitted through blood, semen, great milk, vaginal fluids
AIDS
caused by the human immunodeficiency virus
there is no cure for aids
chronic, potientialy life-threatening conditions
Chlaymdia
can spread to other parts of the body
infect both women and men
doesn't cause any symptoms and can be easily treated
it can make it impossible to get pregannt
prostate cancer
2nd most common cancer among men
may not have early stages
high symptoms are touble urinating
blood in semen, bone pain
Gonorrhea
caused by sexually transmitted bacterium
affects the urethra, rectum or throat
in females can affect the cervix
spread during vaginal, oral or anal sex
