Ribs are a crucial part of your body's bony structure. For Class 7 students, here's a simple definition: Ribs are the curved bones that form a protective cage around your chest.
Understanding Ribs
Think of your ribs as a protective shield for your vital organs. Here's a more detailed look:
- What They Are: The bony framework of the thoracic cavity. The thoracic cavity is the space in your chest that holds important organs. (Reference: Ribs Definition)
- Shape: They are flat, narrow, and curved strips of bone. (Reference: Ribs Definition)
- Where They're Found: Ribs are present in all vertebrates (animals with a backbone). (Reference: Ribs Definition)
How Ribs Connect
Ribs don't just float in your chest! They connect in specific ways to provide structure and flexibility:
- Back Connection: Each rib is attached to your backbone (vertebrae) on your back. (Reference: Ribs Definition)
- Front Connection: In the front, most ribs are connected to the breastbone (sternum). This connection completes the rib cage. (Reference: Ribs Definition)
The Rib Cage
The ribs, backbone, and breastbone together form the rib cage.
Function of the Rib Cage
- Protection: It protects your heart and lungs from injury.
- Breathing: It helps you breathe by expanding and contracting as you inhale and exhale.
