Do insects have hearts

Answer 1

yes, insects have hearts






No not all insects have hearts, but some have a heart like organ or anything else that acts similar to a human's heart. Also, some insects don't have hearts because they don't have any blood.

Answer 2

Yes, some do. Gnats aren't actually real insects, it's just a name people call very tiny flies. Some of them bite, which will swell up due to a small allergic reaction, like a mosquito bite, but generally they feed on nectar and won't bother you.

Answer 3

It is not known whether gnats have emotional feelings. Researchers lack agreement on the definition of emotional feelings and of emotions even though a study published May 14, 2015, in the journal Current Biology, by California Institute of Technology Biology Professor David Anderson breaks emotions down into negative feeling (valence), impacted behavior (persistence), heightened emotional response (scalability), disrupted behavior (generalization) and similar reaction to unrelated stimuli (trans-situationality) while asking the same question of fruit flies. The evolutionary path and the neurological systems of gnats and of people remain dissimilar even though the flight of fruit flies and of gnats from swatter-wielding backyard revelers may evidence the insect equivalent of negative emotional feeling-laden fear.

Answer 4

Yes, insects have a simple tubular heart that pumps hemolymph (insect blood) throughout their bodies. This heart is located on the dorsal side of their abdomen and is responsible for circulating nutrients and oxygen to their tissues.

Answer 5

stupid who cares lol
