Match the following parts of the respiratory system with their functions:

Trachea = Connects the larynx to the bronchi and allows air to pass through to the lungs Bronchi = Two large airways that branch off from the trachea and deliver air to the alveoli in the lungs Lungs = Main organs of the respiratory system responsible for the exchange of oxygen and carbon dioxide Diaphragm = Dome-shaped muscle that plays a crucial role in the process of breathing Signup and view all the answers

Match the following functions of the respiratory system with their descriptions:

Breathing = Involves the inhalation of oxygen-rich air and the exhalation of carbon dioxide Gas Exchange = Enables the exchange of gases between the air and the bloodstream Regulation of pH = Helps maintain the body's acid-base balance by regulating the levels of carbon dioxide and bicarbonate ions in the blood Voice Production = The larynx is responsible for this function, enabling us to speak and communicate Signup and view all the answers

Match the following ways to take care of the respiratory system with their descriptions:

Avoid Smoking = Smoking damages the lungs and significantly increases the risk of respiratory diseases Maintain a Healthy Diet = A balanced diet rich in fruits, vegetables, and whole grains provides essential nutrients for the respiratory system's health Stay Active = Regular exercise helps improve lung capacity and strengthens the respiratory muscles Get Vaccinated = Immunizations against respiratory infections such as influenza and pneumonia can help prevent severe illnesses Signup and view all the answers
