The main function of the respiratory system is gas exchange during which oxygen from the atmosphere is transferred into the bloodstream and carbon dioxide from the bloodstream is expelled into the atmosphere. The three major parts of the respiratory system are the airways, the lungs, and the muscles of respiration. All work together to carry out their task. The airway (nose, mouth, pharynx, larynx, trachea, bronchus etc.) is the passage through which air reaches alveoli, the functional unit of lungs. Gas exchange takes place at alveolar-endothelial membrane. The muscles of respiration, such as the diaphragm, work in unison to pump air into and out of the lungs whilst breathing.
The lungs are the primary organs of respiration in humans. Humans have two lungs, which are situated within the thoracic cavity of the chest. Major function is gas exchange. The lungs possess several characteristics which protect against infections.They are involved in the maintenance of homeostasis. They help in the regulation of blood pressure as part of the renin-angiotensin system. The lungs are involved in the blood’s acid-base homeostasis by expelling carbon dioxide when breathing. The lungs also play a pivotal role in speech by providing air and airflow for the creation of vocal sounds
