How does our body work?

In Natural Science, we are learning about the different body systems. Here you have some videos to review at home.

THE DIGESTIVE SYSTEM

THE RESPIRATORY SYSTEM

THE CIRCULATORY SYSTEM

Bones and muscles

Hi dear students,

In Science we have started to learn about our body, specially we are working with our bones and muscles.

Here you have a video to watch at home. Next day I will ask some questions to you!

As the video is a bit long, I summarize the most important ideas:

• Bones are hard and they are made of calcium.
• All bones are connected by joints to form the skeleton.
• The femur is the largest bone.
• Muscles are soft and they expand and contract moving our body.
• The smallest muscle is inside our ear.
• Your bones and muscles will grow in good condition if you: eat heatlhy, do exercise and maintain a correct posture.

How our body works...? Respiratory, circulatory and excretory systems

Our respiratory and circulatory systems move oxygen thorugh our bodies. This is a part of nutrition.

The respiratory system allows us to get oxygen from the air.

The circulatory system sends blood from the heart to all parts of our body.

The excretory system helps us get rid of waste products.

The digestive system

In Natural Science we learn how our body works. This week we are focused on THE DIGESTIVE SYSTEM.

VIDEO

The digestive system has got 4 essential parts:

1. MOUTH
2. ESOPHAGUS
3. STOMACH
4. INTESTINE

Everybody has a body!

Super skeleton!

Do you know...

• What is the main function of the skeleton?
• Are bones hard or soft?
• What is the biggest and longest bone?
• Where is the smallest bone?
• How many bones do we have?

Try to answer to these questions by watching this interesting video:

The Reproductive and Excretory systems

The reproductive system allows us to have babies.

The excretory system helps us eliminate waste products.

The Respiratory and Circulatory Systems

 These two systems move oxygen through our bodies. This is part of nutrition.
