Internal Structures
Grade 4 · Science · Animal Structures · Quebec, Canada
Lesson Summary
Internal structures are inside the body, like bones, a heart, and lungs. They keep the animal alive and working properly.
Explanation
Just like external structures, internal structures have important jobs. The skeleton gives the body shape and support. The heart pumps blood to deliver oxygen and nutrients to every part of the body. Lungs take in oxygen from the air and release carbon dioxide. The brain controls everything the animal does, from moving to thinking. All these internal structures work together like a team to keep the animal healthy.
