Female Reproductive System
Ovaries
One is
present on each side of uterus
Produce the ovum/egg
Secrete
estrogen and progesterone
Fallopian Tube
Site of fertilization
Exist in pairs
Receives ovum from ovary
Uterus
Pear shaped hollow muscular structure
Foetus develops here
Placenta attaches embryo to uterine wall
Cervix
Vagina
Tube like structure where sperm discharge occurs
Placenta
It's a
tissue that provides nutrition to embryo and gets rid of its wastes
Male Reproductive System
Testes
Produce sperms
- male gamete
Produce secondary sex hormone testosterone
Vas Deferens
Tube which
carries sperms to the seminal vesicles
and also
stores sperms temporarily
Site of mixing of sperms with secretions from glands
Scrotum
Pouch inside which testes are placed
as
sperms require a temperature lower than that of the body
Penis
Inserted into vagina to ejaculate sperms for reproduction
Seminal Vesicles
Produce a viscous fluid which helps sperms to move in fallopian tube and provide them nutrition
Prostate Gland
Produces a milky fluid which aids in mobility of sperms
Urethra
Carries urine from ureters and sperms from vas deferens
Menstruation
Every month, the ovary releases 1 egg
for fertilization, and
uterine lining thickens to receive fertilized embryo
If the egg is not fertilized
, it lives for 1 day and then
it is washed away along with uterine lining through the vagina
