ATI TEAS 7

TEAS Reading Practice Test

1. What role do the spiracles play in the respiration of the insects described in the passage?

A. They allow insects to breathe atmospheric air even when submerged.
B. They protect the insect's internal organs from water pressure.
C. They filter oxygen from the water for underwater breathing.
D. They are used to expel carbon dioxide from the body.

Correct answer: A

Rationale: The spiracles in insects serve the crucial function of allowing them to breathe atmospheric air even when submerged. The passage explains that insects have a system of branching air-tubes that carry atmospheric air with oxygen to all tissues. The air enters these tubes through paired air-holes or spiracles, enabling insects to respire even when they are underwater. Choices B, C, and D are incorrect because the spiracles do not protect internal organs from water pressure, filter oxygen from water for underwater breathing, or expel carbon dioxide from the body. The primary role of spiracles is to facilitate respiration by allowing insects to access atmospheric air.

C. 800
D. 900

This conflict contributes to the divisive nature of discussions surrounding the use of plastics. Choices B, C, and D do not provide contrasting examples that highlight the divisive nature of the topic.
