DIGESTIVE SYSTEM

THE DIGESTIVE SYSTEM

It breaks food we eat into smaller molecules that our body can absorb. The stomach and the intestines are organs of the digestive system.

There are 3 stages in the digestive process:

• DIGESTION: it is the set of changes to food as it travels along the digestive tract. The objective is to transform food into nutrients.
• ABSORPTION: in the absorption stage the nutrients pass to the blood through capillaries which are found in the villi in the small intestine walls.
• EXCRETION: the final stage of the digestive process includes the preperation and elimination of the part of our food that our body does not need.

Let's see how food travels inside your body

PRESENT CONTINUOUS - Theory and practice

PRESENT CONTINUOUS

We use present continuous to talk about something is happening right now.

In affirmative it is formed by:

 subject + verb to be + verb -ing 

Now you have another explanation of present continuous in order to make things easier.

And here, there are some games to have a little fun

• Present continuous  EASY PEASY!
• More practice

UNIT 1 - INVERTEBRATES II

ARTHROPODS


Characteristics

• They live everywhere: on land , in the air and in the water.
  
• It is the biggest group of invertebrates.
  
• They all have external skeleton to protect their body.
  
• They all have many jointed legs.

UNIT 1 - INVERTEBRATES

Invertebrate animals do not have an internal skeleton (backbone) and they are all oviparous (they all reproduce laying eggs).

Let's know something more about invertebrates such as the characteristics or the classification.
