The Skeletal System? The skeletal system is our frame work and it protects our organs. Our skeletal system is made up of bones. Our bones help us move by working with the muscles in our body.
What are Bones? Bones are hard whitish sticks that make up the human skeleton. They are made of calcium and connective tissue.
How are Bones Connected? Bones are connected by ligaments. Ligaments are tough stringy materials that are attached to each bone in order to connect them.
Muscular System
What is the Muscular System? The muscular system is the organ system responsible for movement of the body connected to the bones.
What are Muscles? Muscles are bundles of tissue in the human body.
How are Muscles Connected to Bones? Muscles are connected to bones by tendons. Tendons are flexible strong cords that hold muscle to bone.
Digestive System
What is the Digestive System? The digestive system is a group of organs working together to convert food into energy for the entire body to use.
The Many Parts of the Digestive System and What they Do Mouth(breaks food) Esophagus(transports food to stomach) Stomach(breaks down food into thick liquid) Small intestine(absorbs nutrients from food we eat) Large intestine(converts food into feces)
