REPRODUCTION

INTERACTION

NUTRITION

It functions all the time (day and night) as an involuntary movement.This system is like a transport that takes blood to all parts of the body.

It also works all the time as an involuntary act. It takes the oxygen from blood and expel the carbon dioxide.As fast we breath as much oxygen we need.

Once the digestive system has extracted the NUTRIENTS, the excretory system gets rid of the waste.

The main part is the BRAIN that controls everything. One or more senses send a message to the brain along the nerves. The brain sends instructions back along the nerves to the locomotor system to react.

Interaction systems

Nervous system

It is made up of bones, joints and muscles and allows us to move.When the locomotor system receives an instruction from the brain it goes into action.Some bones protect organs (The ribs protect the lungs and heart. The skull protects the brain)

Like all living things, humans reproduce to make more living things of the same type. A tiny egg (produced into the female reproductive system) is fertilised by a sperm (produced into que male reproductive system) and an embryo develops. During nine months is growing inside the uterus until is ready to be born..
