Collection: Respiratory System

The Respiratory System is composed of the lungs and a network of respiratory passages, working together to facilitate breathing. This system enables the intake of oxygen, which is essential for cellular function, and the expulsion of carbon dioxide, a waste product of metabolism. Air enters through the nose or mouth, travels down the trachea, and into the lungs, where oxygen is exchanged for carbon dioxide in the alveoli. The diaphragm and other muscles aid in the expansion and contraction of the lungs, ensuring efficient airflow. By maintaining the balance of oxygen and carbon dioxide, the Respiratory System is vital for sustaining life and supporting overall bodily functions.
