00:00Hi kids! Today we will learn about organ systems.
00:08Kids, this is our body.
00:14Our body has various external as well as internal body parts.
00:21The parts of our body that we see are our external body parts.
00:29And the body parts that we can't see like our lungs, heart, stomach and brain
00:36are our internal body parts and they are called internal organs.
00:44Each internal as well as external body part has its own function.
00:51Our body works like a machine where each organ performs a specific function.
00:58And organs of our body do not work alone.
01:05A number of organs are connected to perform a particular function.
01:11And such organs connected together makes an organ system.
01:17Let's learn different organ systems in our body.
01:23Organs like stomach, pancreas, small intestine, large intestine work together to make our digestive system.
01:36The digestive system breaks down the food we eat into smaller units called nutrients.
01:46The nutrients are then absorbed into the blood.
01:50So digestive system helps us in taking food and making it ready for use in the body.
02:01Now let's learn about the respiratory system.
02:06The airway, lungs and muscles of respirations forms our respiratory system.
02:15Respiratory system helps us in respiration or breathing.
02:22Breathing gives oxygen to our body and take away carbon dioxide from our body.
02:31Oxygen helps to burn the food to get energy.
02:37The lungs are the main organs of the respiratory system.
02:45Now let's learn about excretory system.
02:50Organs like kidneys, bladder and urethra makes our excretory system.
03:00Function of excretory system is to remove the waste material from our body.
03:08Now let's learn about circulatory system.
03:13Heart, arteries, veins and blood makes our circulatory system.
03:22It carries blood to all parts of the body.
03:27Now let's learn about our skeletal system.
03:33Bones of our body forms our skeletal system.
03:40It gives shape and support to our body.
03:46Framework of bones also protects our delicate internal organs.
03:54Like our skull protects our internal organ, brain.
04:00The rib cage protects our lungs and heart.
04:08We can stand, sit, walk and move because of our bones.
04:17There are 206 bones in the body of an adult human.
04:24Now let's learn about the nervous system.
04:29The nervous system consists of the brain, spinal cord and different types of nerves.
04:40It receives messages from the sense organs and other parts of the body.
04:47And sends orders for the action.
04:52The nervous system is a highway along which your brain sends and receives information about what is happening in the body and around it.
05:04Now let's learn what is muscular system.
05:10Muscular system is made up of muscles.
05:15Most of the muscles are attached to the bones.
05:19Bones and muscles work together.
05:23The system of bones and muscles helps us to do different kinds of work.
05:30All the body movements are possible because of muscles and bones in our body.
05:37So kids, today we learned a lot about human bodies.
05:43Now you may go ahead and take a quiz to learn more.
05:47Bye-bye.
