:red_flag: HUMAN REPRODUCTIVE SYSTEM :red_flag:
Function :silhouette:
Sexual reproduction
The production of new organisms by the combinations of genetic materials found in the nuclei of both female and male sex cells, produced by the reproductive systems of both sexs to form a zygote which develops into a offspring. :star:
Fertilisation
Fusion of sex cells
Fusion of a sperm and a egg cell results in a zygote(fertilized egg) with genetic materials from both parents are combined and passed to the next gen :star:
Heredity
Passing down he genes from 1 gen to anther gen through sexual reproduction is heredity
Asexuality
(science terms) Does not need a mate to reproduce (like just spilt idk) :star:
(human terms) Having no sexual attraction to anyone or gender , having no sexual attraction
Children inherit diff traits from both parents and each individual is still unique / not identical to parents /inheriting genes is a random process that can get you any kind of genetic combo / genetic lottery :star:
how they work tgt :person_with_ball: :person_with_ball:
PUBERTY :black_flag: :star:
Process of physical change where child body matures in adults and is capable of sexual reproduction :star:
Increase in hormones and sex hormones causes this change
Comparisons between male one and female one :star:
Males
facial hair growth
deepening of voice
muscle strength increased
production of sperms
enlargement of penis
Females
development of breasts
menestration :skull:
maturation of eggs
hips become rounder and broader
Both
growth in height and body mass
growth of pubic hair
development and enlargement of sex organs
Females :star:
Ovary
produce eggs
produce female sex hormones that control sexual development in the body
Oviduct/ fallopian tube
site of fertilization
A tube where an egg goes through every once a month from the ovary
Uterus
Where the embryo develops into a foetus during pregnancy
Cervix
Opening of uterus
connects uterus to vagina
keeps uterus tightly closed during pregnancy for safe foetus development
Vagina
Birth canal
site of sperm deposit
Males :star:
Sex glands
Produce fluid to noirish the sperms
Spermduct
Takes the sperms to urethra from testes
urethra
allow sperms and urine to pass through and out of the body at diff timings
Testes
produce sperms
produce male hormones that control sexual development of the body
Penis
Deposit the semen into the vagina during ejaculation
Ovulation :star:
monthly release of mature egg from embroyo
Stop when about 50 years of age(menopause)
Fertilization :star:
sperm nuclei and egg nuclei become 1 big nuclei(zygote)
sperm cell meet egg cell at oviduct
sperm cells swim from vagina to cervix to uterus to oviduct
deposition of semen in vagina
Implantation :star:
Embroyo implants itself into wall of uterus
The embroyo travels to uterus from oviduct
Fertilized egg will develop into a embryo
menstruation cycle/periods :star:
Usually 28 days but depends of person and body
Prepare reproductive system for fertilization ,implantation and pregnancy
Day 1-5
Uterine lining is broken down together with previously unfertilized egg and discharged out of the vagina
6-9
Uterine line thickens and prepares the uterus for implantation
10-15
most fertile period and during this time, high pregnancy occurance alert
16-28
uterine lining continues to thicken
Will start gain aft day 28
how it can be disrupted :red_cross:
Blocked oviduct
blocked spermduct
Unhealthy sperms
low sperm count
Age lifestyle diet affecting the system
Abortion :star:
NOT a birth control method cos nvr prevent cos alr got foetus lol
Dmg to uterus and cervix, bleed alot
Infertility,highly possible
infection, highly possible
tiredness and body pains
Birth control methods :star:
Temporary
spermicide
intra-uterine device
condom
diaphragm
Rhythm method
Birth control pills
Permanent
tubal ligation
Cut the fallopian tubes and tie it
vasectomy
cut the spermduct and tie it
Substance abuse :star:
too much alcohol
Drugs
Smoking
Babies may be born with low birth weight ,undeveloped immune system, higher risk of infections
Medical advances and the impact on human reproduction and survival :face_with_head_bandage:
STIs :star:
Gonorrhea
syphilis
Human immunodeficiency virus(HIV)
