How Cells Divide, Grow, and Repair the Body

Life Cycle: Cells follow a repeating pattern of growth, work, and division.
Perfect Duplication: Before dividing, cells copy their entire DNA library.
Repair Crew: Damaged tissues trigger nearby cells to multiply and fix them.
Rapid Response: Skin and gut cells divide constantly to replace the old.
Controlled Growth: Healthy cells stop dividing when space runs out.
Organized Stages: Division follows precise steps called mitosis.
Emergency Mode: Injury signals speed up cell growth where needed.
Built-In Timers: Cells know when to divide and when to self-destruct.
Renewal Engine: Every day millions of cells die—and millions more replace them.
Healing Power: Cell division restores tissues after cuts, burns, or strain.
