What is a system?
A system is a group of smaller parts that work together.
The Skeletal System Click me to learn more about this system. The skeletal system is made up of 206 bones. Half of these bones are in your hands and feet. Your bones help to protect your important organs. Our bones come in all shapes and sizes. The biggest bone is our thigh bone called a femur and the smallest bone is in our ear and is called a stirrup.
Main Parts of the Skeletal System
The Digestive System
Your digestive system starts working even before you take your first bite of food. And the digestive system will be busy at work on your chewed-up lunch for the next few hours - or sometimes days - depending upon what you've eaten. This process, called digestion, allows your body to get the nutrients and energy it needs from the food you eat.

The Muscular System
You have about 650 muscles in your body, and they are constantly at work. Some muscles are controlled by you, while others do their job without you thinking about them at all. Still others are found only in your heart and no other place in the body.

The Circulatory System
The movement of the blood through the heart and around the body is called circulation , and your heart is really good at it. It's so good at it that it only takes about 20 seconds to pump blood to every cell in your body.

The Nervous System
The bossy brain sends messages around the body. How? By using nerves. Nerves are bundles of thin threads that carry messages throughout the body, a lot like how phone lines carry conversations. The name for this entire system of bundles is the nervous system , and it runs through the whole body just like those phone lines run through a city. Some of the messages go straight to the big boss, but a lot of them first go through a long bundle of nerves called the spinal cord . The spinal cord is inside your spine.

The sense of sight is very important. It is what we use to see. We see light from the moment we open our eyes in the morning until we go to sleep at night. You also use your sense of sight to see colors.
You use your nose and your sense of
smell to smell things. We can smell lots of different things. Some things smell good, like flowers or your mom's perfume. We like to use our noses to smell good things. But, some things smell bad, like a skunk or a rotten egg.We don't like to use our sense of smell to smell those things.
We can use any part of our bodies and the sense of touch to feel things. There are lots of different ways that things can feel. Some things feel soft while others are hard or rough. And, some things are hot while others are cold.
You use your tongue and your sense of taste to taste things. Everything has a different taste, and your tongue can taste every one. When you taste something that you like, you want to eat more of that. But, sometimes something
tastes bad, and you don't want to eat it.
We use our ears and our sense of sound to hear things. Sometimes, sounds are too loud, and we have to cover our ears so that they don't hurt from the noise. But, some sounds are nice to hear, like pretty music or birds chirping. We like to listen to those kinds of things.
