List of important facts related to human body:

Human Body: The human body is the complete structure of a human organism, consisting of a head, neck, trunk, two arms and two legs. By the time a human becomes an adult, their body is made up of about 50 trillion cells, which are the basic unit of life. The biological organization of these cells ultimately forms the whole body. Chemical level: At the chemical level, the human body is the organizational and functional form of various bio-chemicals, in which the atoms of different elements organize in the form of compounds and conduct biological activities. Among these elements, carbon, hydrogen, oxygen, nitrogen, phosphorus and sulfur are the main ones. When two or more atoms come together, they form a molecule, for example, when two oxygen atoms combine, they form an oxygen molecule, which is written as O2. If a molecule contains more than one atom, it is called a compound. Like water (H2O) and carbon dioxide (CO2), carbohydrates, proteins and lipids are also compounds that are important to the human body.
