REPRODUCTION

If a species doesn’t reproduce itself it will become extinct. When an animal reproduces it creates a new living thing it`s called offspring

Types of Reproduction:

Sexual reproduction

This method needs a male and a female of the same species. The ovum is fertilised by a sperm. An egg carried by the female is fertilised by a sperm from the male.

1.      Oviparous: the embryo grows outside the female body, inside an egg. The female lay eggs and these eggs are later hatch into new offspring.

2.      Viviparous: the embryo grows inside the mother’s body.

3.      Ovoviparous: These animals produce eggs, but the eggs develop and hatch inside the mother. Later the mother gives birth to live young.

Asexual reproduction

It`s when the offspring develop from a part of a parent’s body.

                                               THE FEMALE REPRODUCTIVE SYSTEM

1                    Ovum: the female sex cell. More than one ovum is called OVA.

2                    Ovary: produce the ovum.

3                    Uterus: the embryo develops inside.

4                    Fallopian tube: Connect the ovaries to the uterus.

5                    Vagina: It is a muscular tube that connects the uterus to the outside body.

6                    Vulva: the external part of the female reproductive system.

Male reproductive system

1.      Testes: produce male sex cells called sperm.

2.      Scrotum: It is a sac where the testes are located.

3.      Vas deferens: transport the sperm to the urethra

4.      Prostate gland: produce the semen. Semen carries sperm and gives its nutrients.

5.      Urethra: Is a tube in the penis.

6.      Penis: deposit the sperm

Puberty

Adolescence is the stage between childhood and being an adult. Adolescence is a time of physical, emotional and social change. Puberty takes place during adolescence. Puberty involves all the physical changes that change our body from a child’s body into the body of an adult.

We are born with primary sexual characteristics. They are male or female reproductive system. At puberty secondary reproductive system develop.

Male: male have lower voices and lots of facial body hair

Female: have wider hips grow hair in some places.

FERTILIZATION

Fertilization happens when an ovum and a sperm join to form a new cell called zygote. This cell contains information called genetic information. The offspring has information of the father and the mother.

Fertilisation takes place in the fallopian tube when the ovum is travelling from the ovary to the uterus. If fertilisation doesn’t happen the uterus expels the ovum trough the vagina. With small loss of blood called menstruation.
