Larynx : The larynx is a muscular organ that forms an air passage for the lungs and vocal cord. It is a part of the respiratory system.

Aerobic respiration : Aerobic respiration is a fixed metabolic reaction that takes place in the presence of oxygen, going on in a cell to transform chemical energy into ATPs.
Anaerobic Respiration : Anaerobic Respiration is a process of cellular respiration in which the excessive energy electron acceptor is neither oxygen nor pyruvate derivatives.

Combustion : Combustion is a chemical process that occurs outside living cells or living systems. Combustion is an uncontrolled process.
Respiration : Respiration is a biochemical process that takes place in living cells to release energy. Respiration is a controlled biological process.

Breathing : breathing is a physical process wherefrom the atmosphere air is taken into the body.
Respiration : Respiration is a chemical process or is a chemical change because it takes in oxygen and uses it to release energy when energy is released, whereas breathing is a physical change since it just takes in oxygen.
