Human Skeleton

The human skeleton is a remarkable structure that serves several vital functions for our body.

  1. Support
  • It provides the framework that supports the body and maintains its shape.
  1. Protection
  • The skeleton protects our internal organs; for example, the skull encases the brain, and the rib cage shields the heart and lungs.
  1. Movement
  • Bones act as levers and joints serve as fulcrums. Muscles attach to bones, and when they contract, they pull on the bones to produce movement.
  1. Mineral Storage
  • Bones store minerals, particularly calcium and phosphorus, which can be released into the bloodstream as needed.
  1. Blood Cell Production
  • The marrow in our bones is the site for the production of blood cells.

The skeleton also has a role in homeostasis regulating and maintaining the body's chemistry. For instance, it helps regulate the body's pH and electrolyte balance by absorbing or releasing alkaline salts.
