The parts of the human respiratory system include nostrils, pharynx, oesophagus, trachea, bronchi and lungs. The input of air is through inhaling of oxygen from the atmosphere and output is the exhalation of CO2 into the atmosphere.
What is respiration?Respiration is a physiological process of metabolic activity. In respiration, the body cells completely breakdown glucose in the presence of oxygen and yield ATP as the source of energy.
Respiration also includes breathing - a biological and mechanical process involved in the exchange of gases in the body. The air rich in oxygen enters the body through nostrils. The CO2 produced by the metabolic activities of the cells is expelled out through nostrils into the atmosphere.
Thus, respiration is an important and vital biochemical process for the living organisms.

The smallest unit of a substance that retains its composition and properties is a molecule. It is constructed of two or more atoms connected by chemical bonds. Molecules are the foundation of chemistry. Molecules are designated by their elemental symbol and a subscript indicating their atom count.
Atoms are the fundamental unit of an element. The molecule consists of a nucleus that is encircled by electrons. If an atom's electron shell is not quite complete, it is said to have valence electrons. When two or more atoms collaborate to share their valence electrons from the outer shell, a chemical (covalent) relationship is established and a lower energy state is reached. Atomic bonding causes the release of energy in an exothermic reaction Should the molecule.
