The external organs of our body are eyes, ears, nose, tongue and skin. We can see these organs.
These external organs are our sense organs. Sense organs are important parts of our body because they tell us about our surroundings.
Stand in front of a mirror. Observe our body parts. Our body is made up of many parts. These body parts can be grouped as follows:
Head: Turn your head sideways. Let’s raise our head up and down. We can do these movements due to the neck. Now let us note the other features of our head and their functions.
Neck: The neck rests on the shoulders. Below the shoulders lies the chest, stomach, waist, back and hips. Suppose to pick up a fallen pencil, we need to bend at our waist to pick up the pencil from the floor. We can bend in front, sideways and little at the back.
Arms and legs:
Let’s hold a pencil with our fingers. Swing our arms. Bend our arm at the
elbow. Bend down. Jump up and down. Now let us note which external parts of your body move freely and
also note the functions which can be performed by the external body parts.
Every human being has similar body parts. Yet, we look different from one another. Why?
The shape and size of the body parts differ from person to person. This makes us look different from one another. Thus, even in a crowded room, we can spot our friend easily. The differences in external body features, the height and build of the body make us different from one another. These differences help u to recognize one another.Teeth and its Importance
