One of the most surprising facts about the human body is that a large percentage—about 60%—of the human body is made up of oxygen. While we often think of carbon, hydrogen, and nitrogen as the primary building blocks of life, oxygen plays a vital role in our biological processes. It is a key component of water, which is essential for all living organisms. Moreover, oxygen is crucial for cellular respiration, the process by which our cells generate energy. This element is not only foundational to our biology but also constitutes a significant part of the Earth’s atmosphere and the oceans, highlighting its importance in both our bodies and the environment. Understanding the prevalence and role of oxygen can reshape our perspective on health, life, and the interconnectedness of all living things.
