Wow! We’re already three systems in! Next up on our list of the body’s systems to learn about is the skeletal system. The skeleton is made up of bones, which act as the body’s support system.
Here are some of the most important bones in your body:
- Skull – Protects the brain and sensory organs (eyes, ears, etc.), making it vital for protecting the central nervous system.
- Spine (Vertebral Column) – Protects the spinal cord, allows flexibility, and supports the body’s weight. It is crucial for movement and posture.
- Femur – The thigh bone is the longest and strongest bone, supporting much of the body’s weight during movement, walking, and running.
- Pelvis – Supports the upper body’s weight while standing, walking, and running, and protects vital organs such as the bladder and reproductive organs.
- Rib Cage – Protects the heart and lungs, two of the most vital organs for survival.
The skeletal system is super cool! Some facts about it are: as a child, you have around 270 bones, but as you get older, some of them fuse together to get 206 bones. Another fact is that there are different types of bones, including Long bones, Short bones, Flat bones, Irregular bones and Sesamoid bones.
In the end, each body system makes its own contributions to the body, and the skeletal system is no different!
