How oxygen gives your body energy——every second

Introduction

Oxygen is essential for life. Every cell relies on it to produce energy.

Air enters the lungs, where oxygen passes into the bloodstream through tiny air sacs called alveoli.

Inside cells, oxygen helps convert nutrients into usable energy through cellular respiration.

Low oxygen levels reduce energy production, leading to tiredness and shortness of breath.

Efficient oxygen delivery supports physical performance and mental clarity.

Every breath fuels the reactions that keep your body alive.
