1. My body.
Human body is awesome. Think about all the things you can do: you can run, you can jump, you can swim, you can climb... I do not know any machine which can do all those things, do you?
But remember: you must be healthy and nimble to be able to do all the things we said. If you do not usually practice any sport, or you stay for hours in front of your TV or playing video games... your body will not help you when you need it!
I am sure you know all their names, but let’s see this video which show us the parts of the body. Silence, please.
In the picture below (or next to) this text, you can see the name of our main body parts. There are more of them, of course, but we'll talk about it in the school years to come.
Now... Would you be able to build a skeleton by yourself? I'm pretty sure you can.
With the help of an adult, tap or click on "Inside the human body" banner below, choose "Game", find the "skull" and there you go.
Now, let's talk about:
- Bones.
- Muscles.
- Joints.
All of them are components of the Locomotor system. They make it possible for us to move.
LOCOMOTOR SYSTEM
Bones are rigid organs that constitute part of the skeleton of vertebrates.
Muscles produce force and cause motion.
Joint is the location at which two or more bones make contact.
BONES. THE SKELETON.
The skeleton is the body part that forms the supporting structure of an organism. The human skeleton consists of both fused and individual bones.
The functions of the skeleton are:
- Support: the rigid skeleton forms a framework for the support of the body.
- Protection: It provides protection for delicate vital organs of the body.
- Muscle attachment: the bones serve as firm and adequate surfaces for attachment of muscles by means of tendons.
- Movement or Locomotion: many bones act as levers. When muscles pull these levers, they produce movement of the parts, such as bring about locomotion.
- Production of blood corpuscles.
MUSCLES
They do everything from pumping blood throughout your body to helping you lift your heavy backpack. You control some of your muscles, while others — like your heart, for example — do their jobs without you thinking about them at all.
JOINTS.
Remember: a joint is the location at which two or more bones make contact. They are: neck, shoulder, elbow, wrist, waist, knee and ankle.
- Remember: When we finish our P.E. lesson, we have to tidy up.
And this is the end of the topic. Keep working!
