Walking keeps the gills moving and oxygenated water moving under the carapace.
Nervous system controls respiratory system .

The excretory system of crayfish, which involves specialized structures called green glands for waste removal, is unlike the human excretory system, which primarily relies on the kidneys. The respiratory system of crayfish, which involves gills for gas exchange, differs from the human respiratory system that uses lungs.

The respiratory system is the system that handles breathing.
The Respiratory System
Exoskeleton: Crayfish have a hard shell, and no bones. That makes crayfish invertebrates (no spine). Gills: Crayfish respire underwater through gills, where humans use lungs. The circulatory system is the second one, the reason for this being that crayfish have no blood vessels (and humans obviously do).
The trachea is the airway in the respiratory system.
