검증된 단계별 안내1
Begin by understanding that the human body is composed of various elements, each contributing to different physiological functions.
Recognize that the most prevalent elements in the human body are oxygen, carbon, hydrogen, and nitrogen, which together make up the majority of the body's mass.
Consider the role of oxygen, which is a major component of water (H₂O) and is essential for cellular respiration, making it highly abundant in the body.
Evaluate the presence of carbon, which forms the backbone of organic molecules, including proteins, carbohydrates, and lipids, but is less abundant than oxygen.
Conclude that oxygen is the most prevalent element in the human body due to its significant presence in water and its critical role in metabolic processes.
