The Anatomy of Pranayama: Understanding Our Breath

“Full body breathing is an extraordinary symphony of both powerful and subtle movements that massage our internal organs, oscillate our joints, and alternately tone and release all the muscles in the body. It is a full participation with life.” Donna Farhi, The Breathing Book
Breathing is a simple act we have performed since the moment we were born, but for many of us only becomes illuminated within our yoga practice. We might go all day without noticing our breath until the moment we come to the mat – and observe. Of all the functions of our body, the act of breathing is one of the most fascinating. It is completely subconscious yet we can exert conscious control. It is a muscular act, yet one also controlled by the laws of science that govern molecules of gas. It sustains our life, nourishes our organs, helps expel waste from our body, and can affect our emotional state by acting on our nervous system. Understanding exactly how our body performs this extraordinary act can bring us deeper into our pranayama (breathing) practice.
The Path of the Breath
As we breathe in through the mouth and nose, air flows into our trachea (windpipe) and divides into tree-like right and left bronchi and into the lungs into smaller branching bronchioles. These end in alveoli which are the main site of oxygen and carbon dioxide gas exchange. The lungs are actually dense, sponge like organs that extend from just above our clavicle (collarbone) to our lower ribs. Our right lung is larger than our left due to the close proximity of the heart to the left lung.
The driving force behind our breath is one of the most important muscles in the body: the diaphragm. It is a dome shaped muscle that attaches from our sternum (chest bone) at the front, wrapping around the inside of our lower ribs seven through twelve, and to our spine via finger like projections to L1-4 vertebrae. It separates the organs of our chest from our abdominal and pelvic organs. It also has openings for blood vessels to travel through as well as two muscles: the quadratus lumborum and the psoas muscle. This close relationship with two important muscles of the lower back and pelvis may partly explain why people with low back pain have altered breathing patterns.
As we inhale the diaphragm lowers, and as we exhale the diaphragm relaxes and rises up....
