Elements that Make up the Human Body
Elements that Make up the Human Body. Which elements of Periodic Table are essential for our body? What is composition of my body? Composition of human body, human body, periodic table, elements in human body, elements in human body percentage, elements in human body quantity, quantity of elements in human body, role of elements in human body, role of elements in body, role of elements in living organism, chemistry link to health, elements essential to health, elements essential for human body, major elements in human body, microminerals and macrominerals, macrominerals, microminerals, trace elements, biology. In this video, you will come to know typical amount of essential elements in the human body.
Of all the elements, only about 20 are essential for the well-being and survival of the human body. Of those, four elements—oxygen, carbon, hydrogen, and nitrogen—which are representative elements in Period 1 and Period 2 on the periodic table—make up 96% of our body mass. Most of the food in our daily diet provides these elements to maintain a healthy body. These elements are found in carbohydrates, fats, and proteins. Most of the hydrogen and oxygen is found in water, which makes up 55 to 60% of our body mass. The microminerals—Ca, P, K, Cl, S, Na, and Mg—are located in Period 3 and Period 4 of the periodic table. They are involved in the formation of bones and teeth, maintenance of heart and blood vessels, muscle contraction, nerve impulses, acid–base balance of body fluids, and regulation of cellular metabolism. The microminerals are present in lower amounts than the major elements, so that smaller amounts are required in our daily diets. The other essential elements, called microminerals or trace elements, are mostly transition elements in Period 4 along with Si in Period 3 and Mo and I in Period 5. They are present in the human body in very small amounts, some less than 100 mg. In recent years, the ability to detect small amounts has improved so that researchers can more easily identify the roles of trace elements. Some trace elements such as arsenic, chromium, and selenium are toxic at high levels in the body but are still required by the body. Other elements, such as tin and nickel, are thought to be essential, but their metabolic role has not yet been determined.
