Three Stages of Breathing
To understand why breathing process
can be so transformative, it helps to know a little bit about the physiology of
breath. Even though we take it for granted as a simple part of life, breathing
is a complicated process that involves three distinct stages. They are:
External Respiration: The first stage moves oxygen in to the body, across the
membranes of the lungs and in to the blood stream. At the same time carbon
dioxide, a waste produced by metabolic processes, moves in to the opposite
direction and is expelled from the body by exhalation. This first stage is
called external respiration, is what we normally refer to as breathing.
Internal Respiration: The red blood cells bear fresh oxygen throughout the
circulatory system, preparing the body serving the life giving oxygen to all
other cells of the body.
Intra cellular Respiration: Once internal respiration happens, intracellular
respiration occurs as the cells make use of the oxygen for growth repair and
replication. This use of oxygen in cellular metabolic processes is the third
stage, intracellular respiration.
Oxygen plays a major role in metabolic process. Each and every cells in our
body produce energy. They grow, repair and replicate by its own. The glucose
which has reached in every cell after digestion is converted into energy using
oxygen. This is a continuous process which is called metabolism.
