01:42Limbs

01:44We have two limbs. Upper limbs and lower limbs. We have two upper limbs.
01:50They have small parts called hands and arms. Each hand consists of fingers and thumbs. The arm consists of wrist, forearm, elbow and shoulder.
02:03We use our upper limbs. We use our upper limbs to do various activities. Eat, signal, write, lift things, hold things, paint.

02:43Run, jump, play, sense organs. Our sense organs, the eyes, ears, nose, tongue and skin are also known as magic organs. These magic organs help us learn about the things around us.
03:01The information that our sense organs receive are called sensations. The five senses are sight, hearing, smell, touch and taste. Our eyes, that helps us to see, have eyelids, which can be shut or opened.
03:20We also have tears in our eyes. We also have tears in our eyes. They keep the eyes wet. We hear sounds with our ears. Different sounds help us understand the word around us better.
03:33For example, the honking of a car tells us that we should move out of the way. The sense of taste in our tongue tells us the difference between salty, sweet, bitter and sore tastes.
03:49We breathe and smell things through our nose. The hair in our nose act as a filter and clean the air that we breathe. The sense of touch in our skin helps us feel. They tell the difference between a rough wall and a smooth glass even without looking at them.
04:10Our sense organs help us feel. Our sense organs help us feel. Our sense organs help us a lot in our daily life. So, we should take care of them. Our eyes are the most sensitive organ.
04:21We should not read in dim light or in a moving vehicle. We should visit an eye doctor at least once a year and get our eyes tested.
04:31We should take special care of our ears too. We should not listen to music at very high volume. Some people develop a weak eyesight over time. They use spectacles or contact lenses for clear vision. Similarly, some people cannot hear well and wear a hearing aid which makes sounds loud and clear.
04:55The main internal organs inside our body are the brain, heart, lungs and stomach. Our brain lies in the head. It controls all the organs of the body and their functions.
