This part of the respiratory system filters, warms, and moistens the air as it enters the body.
What is the nose (or nasal cavity)?
This process brings oxygen into the body and removes carbon dioxide.
What is breathing (ventilation)?
This term refers to the process of taking air into the lungs.
What is inhalation?
This small structure within the larynx vibrates to produce sound during speech.
What are the vocal cords (or vocal folds)?
This common condition causes inflammation of the bronchi, leading to coughing and shortness of breath.
What is bronchitis?
These tubes carry air from the trachea into each lung.
What are the bronchi?
The gas that is released during the respiratory process after oxygen is inhaled and the gas exchange has occurred.
What is carbon dioxide?
This process occurs when the diaphragm relaxes, allowing the lungs to expel air.
What is exhalation?
These are the small branches that extend from the bronchi and end in the alveolar sacs.
What are bronchioles?
This chronic condition involves narrowing of the airways and difficulty breathing, often triggered by allergens or exercise.
What is asthma?
This structure contains the vocal cords and plays a key role in producing sound.
What is the larynx?
This function of the respiratory system occurs when oxygen from the alveoli moves into the bloodstream, and carbon dioxide moves from the blood into the alveoli.
What is gas exchange?
The pressure in the lungs drops below atmospheric pressure during this process, allowing air to rush into the lungs.
What is inhalation (inspiration)?
This protective lining surrounds the lungs and reduces friction during breathing.
What is the pleura?
This disease causes the destruction of alveolar walls, leading to difficulty in oxygen exchange.
What is emphysema?
This dome-shaped muscle plays a crucial role in the process of breathing by contracting and relaxing.
What is the diaphragm?
This process that provides oxygen to the cells and removes carbon dioxide.
What is the respiratory system?
The exchange of gases in the body that occurs in the tissues is known as this.
What is internal respiration?
The tiny hairs down the windpipe that move gently to keep mucus and dirt out of the lungs.
What is cilia?
This infectious disease primarily affects the lungs and causes persistent cough, chest pain, and weight loss.
What is tuberculosis?
These tiny air sacs in the lungs are where gas exchange occurs.
What are alveoli?
In the lower respiratory tract, the lungs are separated from each other in the chest cavity, with an important organ in between.
What is the heart?
This mechanism allows for the movement of air into and out of the lungs.
What is ventilation?
This part of the respiratory system helps protect the airway by preventing food from entering the trachea when swallowing.
What is the epiglottis?
This condition, commonly caused by smoking, involves long-term lung damage and difficulty in exhaling air.
What is lung cancer?
