The process of breathing involves the pathway of the human respiratory system and includes the nasal cavities, oral cavities, pharynx, trachea, primary bronchi, secondary bronchi  and lungs with  bronchioles and alveoli present. Breathing is a 2-fold process which includes breathing in and breathing out. During this process, the diaphragm which is the dome-shaped sheet of muscle located below the lungs contracts and expands along with the intercostal muscles to force air in and out of the lungs. Since intercostal muscles are also involved in the process of respiration, deeper respiration results in the movement of ribs too. Hence most of us can consciously breathe in and breathe out by moving the diaphragm alone.

Consciously Breathing with Diaphragm Alone

- The diaphragm is a large muscle located at the base of the lungs.
- Breathing is a process that involves the diaphragm and the intercostal muscles.
- The diaphragm contracts and flattens, pulling air into the lungs, and relaxes, pushing air out of the lungs.
- The intercostal muscles help to expand and contract the ribcage, allowing for more air to enter and exit the lungs.
- By making a conscious effort, one can breathe in and out by moving the diaphragm alone, without moving the ribs at all.
- This technique is called diaphragmatic breathing or belly breathing.
- It can be especially helpful for people with respiratory issues such as asthma or COPD.
- Diaphragmatic breathing can also help to reduce stress and anxiety by activating the relaxation response in the body.

During breathing, 20% oxygen is taken in and 15% oxygen is exhaled out. Movement of diaphragm is very important during breathing process. Ribs will also move in and out with the diaphragm. It is not possible to breathe by moving the diaphragm along without moving ribs. Even after forceful exhalation, lungs are never fully emptied. Residual volume, that is minimum amount of air in lungs always remain at all times. Eustachian tube connects middle ear cavity with nasopharynx and hence, one can breathe out air through it by closing both nose and mouth.
