A human body is defined as the complete structure of a human being, which mainly comprises a head, neck, stomach trunk, arms, hands, and the limbs. Apart from these, there are many different types of cells, tissues and several other biological systems that are mainly involved in carrying out different types of specific functions essential for everyday living.
