New Models for New Control Systems

Understanding hemocoel dynamics so as to be able to model a hemocoel might lend novel insight to creating potentially useful control systems for our smallest devices if we could reduce the number of centralized controllers and their connecting 'wires.' Remember: too much fluid within a pump-tube system, such as our heart and blood vessels, can cause pump failure (congestive heart failure) leading to overall system failure (death). One human remedy is to take a diuretic to eliminate the excess fluid and to increase cardiac function with digitalis, but during fluid overload or paucity, all organs of a hemocoel continue to function without any tampering from without. In insects especially, most adjustments are local. Many physiological regulators reside in close proximity to the functions they control so transport is by definition short. Short distances mean fewer 'wires,' shorter wires, and less weight.

Molting becomes now our example of system wide control during metamorphosis. As old cuticle degrades and new cuticle grows, the hemocoel is a reservoir for recycled parts and energy. Even though adult bees do not molt, many insects do, and in bees, cuticle renews just before metamorphosis when a bees passes from larva to pupa and from pupa to adult.
