Question

1. Trachea 2. Book lungs 3. Gills 4. Skin

• A. 2 and 3
• B. 1 and 3
• C. 1, 2 and 4
• D. All the above

Answer 1

The correct option is D

All the above

Arthropods have a complex internal design, with ganglia for a brain and an organ that acts as a heart. They have a complete digestive and excretory system. They also have well-developed sensory organs, that include antennae, eyes, and in some cases internal ears. Respiration occurs through the body surface, gills, trachea, and/or book lungs. The oxygen is carried in an open circulatory system (humans have a closed circulatory system).
