Did you know that about 60% of the human body is made up of water, but the most abundant element in your body is actually oxygen? Although water comprises a large part of our physical makeup, oxygen is the key element found in organic molecules, such as proteins, fats, and carbohydrates, which are essential for life. This means that when we consider our body's composition, oxygen is not just important for respiration, but it also plays a critical role in the structure and function of the molecules that make up our cells. In fact, approximately 65% of the mass of the human body is made up of oxygen atoms, making it the most prevalent element, followed by carbon, hydrogen, nitrogen, calcium, and phosphorus. This fascinating interplay of elements underscores the complexity of life and the intricate chemistry that supports our existence.
