Accepted Answer

The three most abundant elements in the body are carbon, hydrogen, and oxygen. These elements are the building blocks of many molecules in the body, such as carbohydrates, lipids, and proteins. Calcium, sodium, and potassium are important electrolytes in the body, but they are not as abundant as carbon, hydrogen, and oxygen. Nitrogen is also an important element in the body, but it is not as abundant as carbon, hydrogen, and oxygen either.
