Class X Science Notes – Human reproduction and reproductive health

Male reproductive system

Testis, epididymis, vas deferens, seminal vesicles, prostate gland and penis are the parts of the male reproductive system.

Name of the Organ

Location

Structure

Function

Testis

Outside the abdominal cavity in the scrotum

Oval shaped occurring in pairs

i. Production of sperms

ii. Secretion of testosterone

Epididymis

On the side of testis

Coiled tube

Development and storage of immature sperms

Vas deferens

From testis to urethra

Tube-like

Passage of sperms to urethra

Seminal vesicles

In the abdomen near the urinary bladder

Paired tubular gland

Secretion of seminal fluid

Prostate gland

In the abdomen below the urinary bladder

Single globular gland

Secretion of prostatic fluid. Along with seminal fluid it forms ejaculatory fluid. Transport and nourishment of sperms

Penis

Outside the abdomen

Cylindrical muscular organ

Deliver sperms to the site of fertilization

 

Female reproductive system :

Ovaries, Oviducts (Fallopian tubules), uterus and vagina and the parts of the female reproductive system.

Ovaries

Towards the upper side of the uterus in the abdomen

Oval shaped, possess 2-4 million eggs at the time of birth. Of these only about 400 eggs are ovulated.

i. Production of eggs

ii. Secretion of estrogen

Oviducts (Fallopian tubues)

Connecting with the uterus

Tubes carrying eggs

Conduction of eggs to the uterus

Uterus

In the lower abdomen in the middle of the body

Muscular, pear shaped, has strong muscles

i. Keeps the foetus during pregnancy.

ii. Pushes the baby out during labour.

Vagina

In the middle in the lowermost abdomen

Muscular tube opening to the outside on one side and opening in uterus on the upper side.

i. Route for menstrual flow

ii. Pathway for sperms entry

iii. Birth canal
