955 - How does the body grow and repair tissues?

The body grows and repairs tissues with the help of tiny building blocks called cells. Here's a simple explanation:

1. Cells divide: When your body needs to grow or repair tissues, cells in that area divide into two identical cells.
2. New cells grow: These new cells grow and become the type of cells needed for the specific tissue, like muscle cells or skin cells.
3. Cells specialize: Each new cell becomes specialized to do a specific job, like helping your muscles move or protecting your skin.
4. Tissues form: Many specialized cells come together to form tissues, like muscle tissue or skin tissue.
5. Tissues repair: When tissues get damaged, the body sends signals to nearby cells to divide and grow, replacing the damaged cells with new ones.

This process happens all the time in your body, helping you grow and heal from injuries or sicknesses.
