🚩 HUMAN REPRODUCTIVE SYSTEM 🚩

Function 👤

how they work tgt ⛹ ⛹

how it can be disrupted ❌

Medical advances and the impact on human reproduction and survival 🤕

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. ⭐

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 ⭐

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) ⭐

(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 ⭐

PUBERTY 🏴 ⭐

Process of physical change where child body matures in adults and is capable of sexual reproduction ⭐

Increase in hormones and sex hormones causes this change

Comparisons between male one and female one ⭐

Males

Females

Both

growth in height and body mass

growth of pubic hair

development and enlargement of sex organs

facial hair growth

deepening of voice

muscle strength increased

production of sperms

enlargement of penis

development of breasts

menestration 💀

maturation of eggs

hips become rounder and broader

Females ⭐

Males ⭐

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

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

Ovulation ⭐

monthly release of mature egg from embroyo

Fertilization ⭐

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 ⭐

Embroyo implants itself into wall of uterus

The embroyo travels to uterus from oviduct

Fertilized egg will develop into a embryo

Blocked oviduct

blocked spermduct

Unhealthy sperms

low sperm count

Age lifestyle diet affecting the system

menstruation cycle/periods ⭐

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

Stop when about 50 years of age(menopause)

Abortion ⭐

Birth control methods ⭐

Substance abuse ⭐

too much alcohol

Drugs

Smoking

Temporary

Babies may be born with low birth weight ,undeveloped immune system, higher risk of infections

Permanent

spermicide

intra-uterine device

condom

diaphragm

Rhythm method

Birth control pills

tubal ligation

vasectomy

Cut the fallopian tubes and tie it

cut the spermduct and tie it

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

STIs ⭐

Gonorrhea

syphilis

Human immunodeficiency virus(HIV)
