Answer 2

Chemical elements are important in the human body, because -

• The human body is made up of different chemical substances, including raw elements and complex compounds.
• Also, we collect different types of chemical elements from the environment, for our survival. (eg. oxygen for respiration, some necessary chemical elements like Na,H,P,N etc.)
• These internal and externally collected chemical elements are extremely useful in different types of biological activities of our body. Without the right amount of these chemical elements, our body will start malfunctioning.
• That's why, chemical substances are extremely important for our human body.
