The Strange Circulatory System Of Insects
Humans possess what is referred to as a “closed circulatory system,” which means that our blood is contained within veins, arteries, capillaries and the heart. Insects, on the other hand, are quite different, as they do not have all these blood transporting networks. Instead, insects, and all arthropods, have what is called an “open circulatory system” in which their blood sits freely within their bodies. Every one of their organs are bathed within this pool of blood.
Like humans, the insect circulatory system provides its organs with nutrients. On the other hand, the insect’s circulatory system could be thought of as more advantageous than ours. This is because an insect’s blood will clot if their bodies were to become impaled. A human may bleed to death if he/she is impaled or cut on a part of their bodies where blood cannot be stopped. But an insect does not have to worry about bleeding to death in this way due to the fact that their blood will clot at the part of their body where they become injured. This is just one of the many reasons why insects are more resilient and are better adapted to their environments than we humans.
In what ways could the humans closed circulatory system be more advantageous than an open circulatory system?
