Heart and Lungs are one team
/We frequently conceptualize the heart and the lungs as being separate "systems." Safe to say, when we exercise, most people only focus on the heart. And yet heart and lungs are one reality. The only way you separate the heart and lungs is with a scalpel.
The right ventricle pumps the blood into the top of the lungs where the red blood cells pick up the oxygen. The fresh blood then goes back into the left atrium and ventricle of the heart to receive a final pump from the heart into the body. The lungs cradle the heart and feed directly into the heart.
The efficiency of lungs can assist or hurt the heart in so many ways. Praanaayaama practice goes even farther in cleaning the blood supply in the body. When the nitric oxide is turned on from the paranasal sinuses, the effects are multiplied.
The lungs are like "angel wings" of the heart. The lungs can make your heart awareness soar.
Most people talk too much Cardio and not enough Breathio.
