Lung Function and Conditions Assessment

What is the primary function of the lungs?

• To pump blood throughout the body.

• To filter waste products from the blood.

• To exchange oxygen and carbon dioxide with the blood.

• To digest food and absorb nutrients.

Where does the exchange of oxygen and carbon dioxide between air and blood primarily occur in the lungs?

• Bronchi

• Trachea

• Alveoli

• Diaphragm

In restrictive lung diseases, what is the main problem with the lungs?

• They become too flexible and over-expand.

• They struggle to take in enough air.

• They cannot effectively remove carbon dioxide.

• They have too much usable space for oxygen.

Which condition is characterized by difficulty exhaling air from the lungs?

• Fibrosis

• Pneumonia

• Asthma

• Edema

What happens to gas exchange in the alveoli when they are filled with fluid?

• Oxygen diffuses more easily into the blood.

• Carbon dioxide is removed more efficiently.

• Gas exchange becomes less efficient.

• The lungs become drier, improving function.

What is the main problem in a lung condition called pulmonary embolus?

• The airways are blocked by mucus.

• The lungs cannot expand fully.

• Blood flow to parts of the lung is blocked.

• The alveoli are filled with excess fluid.

What is the effect of smoking on the alveoli in the lungs?

• It has no significant effect.

• It enhances gas exchange efficiency.

• It causes inflammation and damage.

• It improves lung capacity.

Which of the following is a common symptom of chronic obstructive pulmonary disease (COPD)?

• Frequent headaches

• Shortness of breath during physical activity

• Increased appetite

• Skin rashes

What role does the diaphragm play in the process of breathing?

• It filters air entering the lungs.

• It helps in the expansion and contraction of the lungs.

• It produces mucus to trap particles.

• It regulates blood flow in the lungs.

What is the primary function of the alveoli in the lungs?

• To filter out harmful particles from the air.

• To produce surfactant to reduce surface tension.

• To facilitate gas exchange between air and blood.

• To transport oxygen to the bloodstream.
