Question

Which of the following functions are performed by the human skeletal system?

1) support
2) protection
3) assistance in movement
4) electrolyte balance
5) acid base balance
6) blood cell production

Answer 1

The human skeletal system performs functions such as support, protection, assistance in movement, electrolyte balance, acid-base balance, and blood cell production.

Step-by-step explanation:

The human skeletal system performs several important functions:

1. Support: The bones of the skeleton provide a framework that supports the body, allowing us to stand upright and maintain our shape.
2. Protection: The skeletal system protects our internal organs. For example, the ribcage protects the heart and lungs, and the skull protects the brain.
3. Assistance in movement: The skeletal system works with the muscular system to allow us to move. Muscles attach to bones, and when the muscles contract, they pull on the bones, moving.
4. Electrolyte balance: The bones store minerals, such as calcium and phosphorus, which are important for maintaining electrolyte balance in the body.
5. Acid-base balance: The bones act as buffers, helping to regulate the pH balance of the body fluids.
6. Blood cell production: The bones contain bone marrow, where blood cells are produced.
