Do mosquitoes heart?
Mosquitoes do have hearts, although the structure is quite different from the human heart. According to Vanderbilt University, the mosquito heart consists of a dorsal vessel subdivided into an abdominal heart and a thoracic aorta. The heart pumps the hemolymph out of the hemocels.

Are mosquitoes vampires?
Out of the millions of species of insects, only about a hundred suck human blood. Now, scientists say they’ve figured out how one mosquito became a vampire: a gene that makes it particularly sensitive to human odor.
What if mosquitoes went extinct?
