Respiratory

From a medical perspective, the term "respiratory" refers to the body's process of respiration—a vital function that involves the exchange of oxygen and carbon dioxide between the environment and the body. This process is central to life, as it enables the inhalation of oxygen, which is required for metabolic processes within cells, and the exhalation of carbon dioxide, a waste product of metabolism. The respiratory system includes the airways (nasal passages, pharynx, larynx, trachea), the lungs, and the respiratory muscles (diaphragm and intercostal muscles) that facilitate breathing.

Diseases and conditions affecting the respiratory system can impair gas exchange and have serious health implications. Medical professionals diagnose and treat various respiratory issues, ranging from acute infections like bronchitis and pneumonia to chronic diseases such as asthma, chronic obstructive pulmonary disease (COPD), and lung cancer. Respiratory function is also a primary consideration in critical care medicine, with life support techniques like mechanical ventilation used to support patients whose breathing is severely compromised. Maintaining respiratory health is essential for overall well-being, and interventions may include medication, pulmonary rehabilitation, and lifestyle changes like smoking cessation.
