Question 21

The term "emphysema" comes from the Greek word "emphysema" which means "puffed up" or "blown into". Among the options, "panting" is related to breathing rate, "swollen" is more about abnormal enlargement due to fluid, "congested" is about blockage, while "puffed up" matches the literal meaning of emphysema (related to the alveoli being over - inflated or puffed up in the disease context).

Hypoxia is defined as a condition where there is a deficiency of oxygen. In the context of blood, it means deficient oxygen in the blood. "Deficient carbon dioxide" is not hypoxia, "excessive oxygen" is hyperoxia, and "excessive carbon dioxide" is hypercapnia.

Answer:

B. puffed up
