Functions
What area helps in sound production as air passes through?
What is the Larynx
What is the function of the alveoli in the respiratory system?
Exchange gases between the lungs and blood
What is the primary muscle responsible for pulmonary ventilation (breathing)?
What is the Diaphragm
Which upper respiratory condition is characterized by inflammation of the sinuses, leading to facial pain and nasal discharge
What is Sinusitis
Which structure serves as a passageway for both air and food?
What is the Pharynx
What aspect of the Respiratory System helps to trap and expel harmful particles?
What is Cilia and Mucous
Which part of the respiratory system connects the larynx to the bronchi and allows air to pass into the lungs?
What is the Trachea
During inhalation, the diaphragm:
Contracts and moves downward
Which lower respiratory condition is a progressive disease that includes emphysema and chronic bronchitis?
What is Chronic Obstructive Pulmonary Disease (COPD)
Which of the following best describes tidal volume?
The amount of air inhaled and exhaled during normal breathing
What role does surfactant play in the lungs?
Surfactant is a fluid produced by cells in the alveoli that reduces surface tension, preventing the alveoli from collapsing during exhalation.
The diaphragm plays a crucial role in breathing by:
Contracting and relaxing to change lung volume
What happens to the pressure inside the lungs during inhalation?
It decreases, drawing air in
What is the primary cause of respiratory distress syndrome (RDS) in premature infants?
What is Lack of surfactant leading to alveolar collapse
What is the primary function of the pleura surrounding the lungs?
What is the primary function of the pleura surrounding the lungs?
What mechanisms does the respiratory system have to filter and warm incoming air?
The Nasal Cavity
What structure prevents food from entering the trachea during swallowing?
what is the Epiglottis
What role do the intercostal muscles play in breathing?
They help expand and contract the ribcage
Which disease is caused by a bacterial infection and can lead to lung damage and a chronic cough with bloody sputum?
What is Tuberculosis (TB)
Which obstructive lung disease is characterized by bronchoconstriction and airway inflammation, leading to wheezing and shortness of breath?
What is Asthma
What is the primary function of the respiratory system?
Exchanging oxygen and carbon dioxide
Which part of the respiratory system is also known as the "voice box" and is responsible for producing sound?
what is the Larynx
What term describes the maximum amount of air a person can inhale and exhale in a single breath?
Vital capacity
In which condition does air enter the pleural cavity, preventing lung expansion and causing a collapsed lung?
What is a Pneumothorax
Which respiratory condition is commonly associated with long-term smoking and leads to the destruction of alveoli?
What is Emphysema
