Question

In 3-5 complete sentences describe the human respiratory system - the organs and their functions

Answer 1

The human respiratory system is primarily responsible for the exchange of gases between the body and the environment. It includes the nose and nasal cavity, which filter, warm, and humidify incoming air; the pharynx and larynx, which facilitate the passage of air and vocalization; and the trachea, which serves as a major airway. The bronchial tree branches into smaller airways leading to alveoli, tiny sacs where oxygen is absorbed into the blood and carbon dioxide is expelled. The diaphragm and intercostal muscles play crucial roles in ventilating the lungs by expanding and contracting, facilitating the inhalation and exhalation process.
