Question

Which organ do insects not have?

Answer 1

Insects do not have lungs as their respiratory system. Instead, they breathe through a network of tiny tubes called tracheae, which carry air directly to their calls. This allows insects to efficiently exchange gases with their environment, even in low- oxygen conditions. 

Answer 2

Insects do not have a heart. Instead, they have an open circulatory system, where blood is pumped directly into the body cavity. This means that insects do not have a single organ that pumps blood around the body.

Answer 3

Insects do not have lungs, instead, they breathe through a series of tiny tubes called tracheae. However, the one organ that insects do not have is a true heart. Instead, they have a long tube-like structure called the dorsal vessel, which pumps hemolymph (a fluid similar to blood) throughout their bodies. The dorsal vessel is aided by openings called ostia that allow the hemolymph to flow back into the vessel.
