Question: 1 / 555

How many cells does the human body replace every day?

Millions

Billions

The human body is a highly dynamic system that involves constant cell turnover to maintain health and function. Each day, the body replaces approximately 50 to 70 billion cells. This astounding number reflects the ongoing processes of growth, repair, and regeneration that occur in various tissues and organs.

For example, cells in the skin, digestive tract, and blood are continuously sloughed off and replaced. The large number of cells replaced daily is crucial for healing, rejuvenation, and maintaining overall homeostasis. The concept of billions of cells being replaced daily highlights the complexity and efficiency of the body's cellular processes, making it essential for overall health. The other options, such as millions, thousands, or even trillions, do not accurately capture the magnitude of cellular turnover that occurs within a 24-hour period.
