EPRODUCTIVE SYSTEM

Live to sustain the strain , similar to themselves to create new creatures called reproduction . All organisms are capable of reproduction .

An organism's genetic material to reproduce , puppies need to transfer . Bisexual (male and female individuals ) in reproducing genetic material is transmitted through germ cells . Reproductive cells called gametes . Male reproductive cells, sperm , the egg gets its name from the female reproductive cells .

Ova ( egg ) :

Egg cells are large and immobile . Provides plenty of nutrients and cytoplasm are many. There is no whip . Fewer eggs produced by sperm .

The male reproductive cell ( sperm ) :

Sperm cells are very small compared to the egg . Less cytoplasm . There is a move with whips and whips . Head, middle and tail section consists of three parts . Thanks to the moveable tail .

The main task of the human reproductive system is the same , but the reproductive system of males and females, there are some differences in the structure . Also köreltils , even one that does not affect an individual's physical health is our system .

Structure of Female Reproductive Organs

Female reproductive organ , a pair ovary, oviduct , uterus ( cervix = uterus) , consists of four sections as the vagina .

1 - Vagina : the uterus and sperm from the uterus to the income tubular structure that moves are . Drop- out is part of the reproductive system . His sperm entry , unfertilized egg cell , and is the place where the baby thrown out .

2 - Ovarian Channel : ovaries to the uterus (womb) that connects the conduits. The eggs produced in the ovaries , fallopian tubes taken with , is transmitted to the uterus through the fallopian tube . About the daily life of a couple of eggs in the ovaries through the channel . Meanwhile, the eggs, if coupled with a sperm , fertilization occurs and the zygote is formed , the zygote multiplies. So the egg cell, the channel uterus , the fertilized referred to as .

3 - Uterus ( Uterine = uterus ) : Thick -walled , composed of smooth muscle of the uterus , where a fertilized egg develops in the womb is clinging . Cell division period and the embryos in the uterus (live draft ) occurs. Creates offspring developing embryo .

If not fertilized egg from here , broken egg cells and tissues in the uterus generated , is thrown out as bleeding from the vagina . This situation menstrual bleeding ( menstruation ) is called. This event is repeated every 28 days .

4 - ovaries ( ovarian ) : A female in the crotch , one right and the other on the left ovaries are two in number . In the ovaries , from puberty until a certain age , the effects of the hormone secreted by the pituitary gland , the average 28-day egg cells are produced . They also secrete sex hormones .

Note: In the female, male , unlike the growth openings and openings of urine excreted is different. So does the urine excreted from the vagina .

Note: while until his death in men sperm production , egg production in the female ends after about 50 years of age . This period is called menopause .

Structure of Male Reproductive Organs

Male reproductive system, testes ( glands ) , vas deferens , seminal vesicles ( glands ) and consist of the penis .

1 - Testes: a couple, settled into the scrotum . Occurs in adult testis sperm production in men . Body temperature is too high for the development of sperm . Located outside the body so testes . Sperm produced in the testes , and the movement is incapable of fertilization . This feature , called the epididymis sperm in the channel gain . The testes also secrete sex hormones .

2 - Sperm Channel : sperm , sperm are stored in the channel . Sperm ducts , prostate gland through the abdominal cavity means . Here, the vas deferens joins with the urinary tract . Passing through the penis , pop out of a common channel .

3 - Seminal Vesicles : prostate and Cowper's glands occurs. They secrete seminal fluid . Seminal fluid , sperm transport and staying in the female reproductive system and provide protection for a short period of feeding .

4 - Penis: Sperm mixed with seminal fluid , is ejected from the channel inside the penis .
