Question

1. the lymphoid tissues located behind the nasal cavity are called:

bronchioles
adenoids
tonsils
paranasal sinuses

1. blebs are:

blood - filled blisters
puss - filled wounds
fluid - filled cavity
mucus - filled papules

Explanation:

Question 1

To solve this, we analyze each option:

• Bronchioles: Small air passages in the lungs, not lymphoid tissue behind nasal cavity.
• Adenoids: Lymphoid tissue located behind the nasal cavity (pharyngeal tonsils).
• Tonsils: Usually refer to palatine tonsils (in throat), not behind nasal cavity.
• Paranasal sinuses: Air - filled cavities in skull bones, not lymphoid tissue.

So the correct option is adenoids.

Analyze each option:

• Blood - filled blisters: Not the definition of blebs.
• Puss - filled wounds: Blebs are not puss - filled wounds.
• Fluid - filled cavity: Blebs are small, fluid - filled cavities (e.g., in lung tissue in some conditions).
• Mucus - filled papules: Blebs are not mucus - filled papules.

So the correct option is fluid - filled cavity.

Answer:

B. adenoids
