"breath"的定义和意义

What is "breath"?

Breath refers to the act of inhaling and exhaling air to facilitate respiration. It is a fundamental process that allows the body to exchange oxygen and carbon dioxide, supporting cellular function and energy production. Breath involves the movement of air through the respiratory system, where oxygen is absorbed into the bloodstream and carbon dioxide is expelled. It is regulated by the diaphragm and intercostal muscles, which control the expansion and contraction of the lungs. Breath plays a vital role in delivering oxygen to the body's tissues, maintaining pH balance, and facilitating the elimination of waste gases. It is also intricately linked to emotional states, stress management, and overall well-being.
