Exercise Physiology – Understanding Breathing – Latest and Best Research 2022

Breathing

Respiration is a necessary activity for human survival. Death can occur within minutes after breathing stops. The role of respiration is to inhale oxygen and exhale carbon dioxide. The human respiratory system is composed of the nasal cavity, throat, trachea, bronchi, lungs, diaphragm and respiratory muscles.

breathing process

When the human body inhales, the diaphragm contracts and moves downward, the respiratory muscles of the chest wall and neck contract, and the chest cavity is pulled upward and outward, causing the chest cavity to expand and the air pressure inside the lung cavity to decrease.

 The air outside the body is thus drawn into the alveoli, and the oxygen in the fresh air penetrates into the tiny blood vessels in the alveoli. The carbon dioxide inside is also excreted into the alveoli.

At the beginning of exhalation, the diaphragm and respiratory muscles relax, and the expanded ribcage retracts to its original position due to its elasticity. The contraction produced during this period exhales the carbon dioxide and residual gas in the alveoli.

For the next breathing exercise, follow this cycle and repeat.

Respiratory function

index There are many indexes to measure respiratory function. The common one is vital capacity (Vital Capacity) refers to the capacity of the air that the human body inhales and then exhales with all its strength. The lung capacity of an average person is about 5 liters. . For more health tips visit our site ArticlesHubs.

Respiratory Care

One way to keep your respiratory system healthy is to not smoke and reduce exposure to exhaust fumes, dust, and harmful floating objects. Because these wastes are inhaled into the lungs, causing irreversible damage to the alveoli and other tissues, and even causing lung cancer. At the same time, participating in a moderate amount of exercise can also enhance the development of respiratory muscles and improve lung capacity. Young people can participate in high-intensity exercise, but the elderly and frail people should choose aerobic exercise, which can also improve the function of the respiratory system.
