Human Body Elemental Composition - Key Elements by Mass #3796954 (License: Personal Use)

This infographic illustrates the approximate elemental composition of the average adult human body by mass: oxygen (65%), carbon (18.5%), hydrogen (9.5%), nitrogen (3.5%), and trace elements collectively labeled “Other” (3.5%). The colored segments correspond to each element’s proportion, with oxygen dominating due to its presence in water and organic molecules. The diagram simplifies complex biochemistry into an intuitive, visually segmented silhouette for educational clarity.

Used in biology, health science, and chemistry education contexts-especially on introductory pages about human anatomy, biochemistry, or nutrition-to help learners grasp the fundamental chemical basis of the human body. Matches user intent for quick factual reference or classroom visual aid.
