Question

question 5
the ____ cavity contains the body organs that sustain homeostasis.
a ventral
b spinal
c cranial
d dorsal

Explanation:

To solve this, we analyze each option:

• Option A (ventral): The ventral cavity (thoracic and abdominopelvic) holds organs like heart, lungs, stomach, etc., which maintain homeostasis (e.g., digestion, circulation).
• Option B (spinal): Spinal cavity holds spinal cord, not major homeostatic organs.
• Option C (cranial): Cranial cavity holds brain, important but not the main cavity for most homeostatic organs.
• Option D (dorsal): Includes cranial and spinal, but spinal has cord, cranial has brain; ventral is where most homeostatic organs (digestive, respiratory, circulatory) are. So ventral cavity is correct.

Answer:

A. ventral
