You need your skeleton! Those bones are your support system, keeping you from collapsing like a deflated basketball. Learn about their other vital functions as well!
Watch the cool video below to see a skeleton in motion.
Wow!
Keep reading to learn what a skeleton is and how important bones are.
Babies are born with about 270 bones, which grow together over time to form the 206 bones found in adults. These bones comprise the human skeleton, an integral part of the human body.
The skeletal system functions to assist humans with movement and support. It interacts with other systems, like the muscular and circulatory systems. The muscular system helps you move, while the circulatory system brings blood into bones.
Bones have a pretty interesting structure. As you watch the video below, respond to the following questions.
The structure of bones is important because they provide stability and support to the entire body. Running, biking, or playing catch would be difficult without strong bones.
Watch the video below to learn about some important bones in the skeletal system. As you learn about each bone, record the name, location, and a quick sketch on the Skeletal Bones Graphic Organizer found under Downloadable Resources in the right-hand sidebar.
You may need to pause or repeat the video to collect all the information.
Your Skeletal Bones Graphic Organizer should now show what you have learned about bone structure and location.
Bones help you grow and move in your environment. It would be tough to function without them because your other systems depend on bones for structure and support!
In the Got It? section, practice identifying bones and learn more about the functions of the skeletal system.
