00:00HUMAN BODY Human body is a wonderful machine.
00:04Our body has different parts which perform different functions.
00:10Let us study about the human body in detail.
00:15BODY PARTS Our body has three main parts, the head, the
00:20trunk and the limbs.
00:30The head contains important organs like the eyes, ears, nose and mouth.
00:48Head has the brain which controls and commands the body.
00:52Head is made up of a bony box called skull.
00:58Brain helps us to understand what we see, hear, feel, taste and smell.
01:05The brain also instructs different parts of our body to move or react to these parts.
01:13Trunk is the middle part of our body.
01:16Trunk protects the important organs of the body like lungs, heart and liver.
01:23The lungs and heart are protected by a cage of bones called the rib cage.
01:29LIMBS Our arms and legs are commonly known as limbs.
01:36The arms have different parts like hands, fingers, nails, wrist and elbow.
01:45Limbs help us to catch things, pick them up, write, play, bathe or take care of ourselves.
01:53We have a pair of legs which help us to walk, run, kick, dance, skip etc.
02:03The different parts of the legs are the thighs, knees, ankles, feet and toes.
02:16INTERNAL PARTS OF OUR BODY
02:20Heart, lungs, liver, stomach and kidneys are the internal parts of our body.
02:28We cannot see the internal parts of our body.
02:32External parts of our body, eyes, nose, ears, forehead and mouth are examples of external parts of our body.
02:44We can see our external body parts.
02:49There are five sense organs in our body.
02:54Eyes, ears, nose, tongue and skin are our sense organs.
03:02Our eyes help us to see.
03:05Our ears help us to hear.
03:08Our nose helps us to smell.
03:12Our tongue helps us to taste.
03:16Our skin helps us to feel.
03:19Eyes help us to see things around us.
03:24Our eyes are very precious to us.
03:27We must clean our eyes regularly to keep them away from any disease.
03:34Ears help us to hear the sound.
03:38There are different types of sound around us.
03:41Some are pleasant and some are unpleasant.
03:45Clean your ears regularly.
03:48To get the wax out of the ears, always use ear buds.
03:53Never put any sharp object into your ears.
03:58NOSE
04:00The nose helps us to breathe.
04:03The nose helps us to smell things around us.
04:08The fine hairs inside the nose traps the dust particles in air and helps us to breathe clean air.
04:17Always keep your nose clean by blowing gently.
04:22Use a clean handkerchief or towel to clean your nose.
04:27TONGUE
04:29The tongue helps us to speak and taste the food we eat.
04:34The tongue can identify whether the food is salty, sweet, sour or bitter.
04:41There are different parts of the tongue which feel different tastes.
04:46The tongue should be cleaned daily.
04:50SKIN
04:52The skin is the outer covering of our body.
04:55The skin helps us to feel different things by touch.
05:01Skin protects the organs inside our body.
05:05The skin stops germs from entering inside the body.
05:10Bath daily to remove all the dirt and germs from the skin.
05:15SKELETAL SYSTEM
05:19There are 206 bones in a fully grown human being.
05:26They make up the skeletal system and give proper shape to the body.
05:32THE MUSCULAR SYSTEM
05:35The muscles are attached to the bones in our body.
05:38Muscles and bones work together and help our body and its parts to move.
05:47THE NERVOUS SYSTEM
05:49The brain, the spinal cord and the nerves make up the nervous system.
05:55Messages from all parts of our body are carried by the nerves through the spinal cord to the brain.
06:04THE BREATHING SYSTEM
06:06The respiratory system is made up of nose, windpipe and lungs.
06:12It supplies oxygen to the blood.
06:15It also removes carbon dioxide from the blood.
06:21THE DIGESTIVE SYSTEM
06:23The breaking down of food we eat into simpler forms is called digestion.
06:31THE EXCRETORY SYSTEM
06:33This system removes the waste materials from our body.
06:38The two kidneys we have throw out waste in the form of urine.
06:44Skin also helps in removing excess water.
06:48THE HUMAN BODY
06:50The human body is made up of cells.
06:53Cells of one kind join to form a tissue.
06:57A group of tissues form an organ.
07:00Organs work together as a system.
07:04Breaking up of food into simpler form is called digestion.
07:09The heart pumps blood to all parts of the body through the blood vessels.
07:15THE SKELETAL AND MUSCULAR SYSTEMS
07:18Help our body to move.
07:20All actions of the body are controlled by our brain.
07:25We see, hear, feel, breathe and taste through our sense organs.
07:31THE EXCRETORY SYSTEM removes waste from the body.
