Seems like silly question because all of us are breathing and know how to breathe? Without breathing there is no life and naturally we learn how to breathe?
But, what might seem like a silly question is actually a very valid question. Do we really know how to breathe properly and what happens during the breathing process?
Each and every cells of our body need oxygen for survival. Cell is a smallest independent unit of life. Different cells unite together to form tissues. Two or more kind of tissues form Organ and a collection of Organ together form a system i.e. our body. Our cells can stay without food and water for several days but cannot survive without oxygen for even 5 minutes .So oxygen is important for us. If you find that the cells are dying it means that diseases are inevitable.
So coming back to the point, the role of our respiratory system is to collect oxygen from atmosphere and deliver it to our lungs and through lungs to the blood. These exchanges of gasses happen in Alveoli sacs of our lungs.
In return blood handovers carbon di oxide to respiratory system which is disposed of in the atmosphere. Carbon di oxide is the waste product of cell which is released during the metabolic process and is like toxic substance for our body.
So when we breathe through our nostrils air passes through the sinus cavity which is warmed by sinus cavity and dust particles and bacteria’s with the air are trapped by mucus and the hairs inside the nose and pure air goes to the lungs .
- Always breathe in through the nose and not through the mouth.
- When we breathe in we must take deep and slow breath. 10-14 breath per minute is good.
- Our lungs can consume up to 5 litres of oxygen, there will be always around 1.5 litres of residual air in the lungs and we cannot empty the lungs completely.
- With shallow breathing we inhale only around 500 ml that should go up to 2500 ml.
- When we breathe in, the stomach must come out but, we breathe wrong and when we inhale our stomach also goes in and our lungs can’t expand completely.
- Diaphragm is a muscle which is separating abdominal and thoracic cavity. When diaphragm contracts, the lungs expand and fresh air is drawn. When diaphragm contract stomach will come out.
So breathe correctly and you can avoid many life threatening diseases.
