What is the Skeletal System?

Your Skeletal system is all of the bones in the body and the tissues such as tendons, ligaments and cartilage that connect them.
Your teeth are also considered part of your skeletal system but they are not counted as bones. Your teeth are made of enamel and dentin. Enamel is the strongest substance in your body.

What does the skeletal system do?

Support
The main job of the skeleton is to provide support for our body. Without your skeleton your body would collapse into a heap. Your skeleton is strong but light. Without bones you'd be just a puddle of skin and guts on the floor.

Protection
Your skeleton also helps protect your internal organs and fragile body tissues. The brain, eyes, heart, lungs and spinal cord are all protected by your skeleton. Your cranium (skull) protects your brain and eyes, the ribs protect your heart and lungs and your vertebrae (spine, backbones) protect your spinal cord.

Movement
Bones provide the structure for muscles to attach so that our bodies are able to move. Tendons are tough inelastic bands that hold attach muscle to bone.
Digestion or the breaking down of food into small molecules that will be absorbed into our bloodstream begins when you put food in your mouth and begin to chew. Your teeth help to break the food apart, saliva helps to soften the food and your tongue helps to push the food into your throat when your'e ready to swallow.
The stomach is a sack that receives the food from the esophagus. Your stomach is located just below the heart. The stomach makes digestive juices (acids and enzymes) that help to break our food down into a thick liquid or paste. This thick liquid or paste is called chyme. Your stomach is a muscular organ that is able to move in order to mix the food with digestive juices. Food usually remains in the stomach for about two hours.

The Circulatory System is responsible for transporting materials throughout the entire body. It transports nutrients, water, and oxygen to your billions of body cells and carries away wastes such as carbon dioxide that body cells produce. It is an amazing highway that travels through your entire body connecting all your body cells.
The blood is an amazing substance that is constantly flowing through our bodies.

Your blood is pumped by your heart.
Your blood travels through thousands of miles of blood vessels right within your own body.
Your blood carries nutrients, water, oxygen and waste products to and from your body cells.
A young person has about a gallon of blood. An adult has about 5 quarts.
Your blood is not just a red liquid but rather is made up of liquids, solids and small amounts of oxygen and carbon dioxide.
Your respiratory system is made up of the organs in your body that help you to breathe. Remember, that Respiration = Breathing. The goal of breathing is to deliver oxygen to the body and to take away carbon dioxide.
Your nervous system is the control and communication system of the body. Its job is to send and receive messages. Your nervous system controls all your thoughts and movements.
The cells that make up the nervous system are called neurons. Long, stringy neurons are perfect for carrying the electrical messages that are the "language" of the nervous system.
