Human body structure diagram (what is the human body made of?)
If someone asks you what the body is made of? I’m sure many kids will ask their parents what my body is made of. You might say that it has tissues such as bones, muscles, nerves, blood, skin, internal organs, etc., or it is further divided into nervous, digestive, and circulatory systems based on physiological anatomy.
This answer is of course correct, but in essence, the human body is made up of elements, including carbon, hydrogen, oxygen, etc. Protein, fat, sugar and water make up 96% of the body weight. After death, people are cremated to produce carbon, hydrogen, oxygen, etc. Gone with the wind, leaving ashes of bones and resources, accounting for about 4% of adult body weight, nutritionally known as inorganic salts or minerals.
Among the non-genetic elements that make up the human body, calcium, phosphorus, potassium, sodium, chlorine, magnesium, sulfur, etc. , accounting for about 3.954% of the body weight, the so-called constant elements, while zinc, copper, iron, manganese, cobalt, chromium, tin, etc. It only accounts for 0.046% of the body weight, which is less than five ten thousandths in total. The content of each element can be seen.
I want to emphasize here that our constant elements usually need a lot, need a lot of supplements, and need to be supplemented every day. In fact, for our trace elements, we don’t need to eat so much. Because now many parents will eat these trace elements with their children in large doses for a long time. In fact, I think it is unscientific. Nutrition must have recommended amounts. We should supplement nutrition scientifically and reasonably.
