Question

1. cystic fibrosis is an inherited exocrine gland disorder that causes thick secretions of _______ to accumulate in the lungs.

○ sweat
○ bile and pus
○ saliva and pus
○ mucus and pus

1. the medical term diphtheria literally means:

○ mucus/condition
○ covering/state
○ pus/disease
○ membrane/refers

Explanation:

Question 25

Cystic Fibrosis affects exocrine glands, leading to thick secretions. In the lungs, it's mucus (thick, sticky) and pus (from infections due to mucus buildup) that accumulate. Sweat is related to its sweat gland impact, not lung secretions. Bile is liver-related, saliva is oral. So the correct option is mucus and pus.

The term "diphtheria" comes from Greek "diphthera" meaning "covering" (like the pseudomembrane in the disease) and "-ia" (state/condition). "Mucus/condition" doesn't fit, "pus/disease" is incorrect, "membrane/refers" is wrong. So "covering/state" matches the etymology.

Answer:

D. mucus and pus
