The process of blood-sucking by mosquitoes may seem simple, but their impact on humans is undeniable.
Let’s take a look at the structure of a mosquito’s mouth. The mouthparts of mosquitoes primarily consist of a pair of sharp needles and a straw-like tube. It is these specialized structures that allow mosquitoes to penetrate human skin and effectively draw blood.
Mosquitoes detect humans by sensing odors, heat, and carbon dioxide emitted by the human body. They can accurately locate the human body and then approach silently.
The blood-sucking by mosquitoes causes some blood vessels to rupture.
Mosquitoes use their mouthparts to pierce human skin. The mosquito’s needle is very sharp and rarely causes significant pain when it enters the human body. Mosquitoes release anesthetics during the bite, so humans often do not feel much discomfort when bitten. Moreover, the saliva of mosquitoes contains antithrombin, which helps facilitate the blood-sucking process.
Mosquitoes possess a specialized straw-like tube, which has serrated edges inside, aiding them in efficiently sucking blood and reducing blood loss. They suck blood very quickly, often taking just a few minutes. After obtaining enough blood, mosquitoes immediately fly away to find a safe place to digest their meal.
The process of blood-sucking by mosquitoes may seem straightforward, but their effects on humans cannot be overlooked. First, the blood-sucking process causes itching and a prickling sensation on the skin. Mosquitoes leave saliva when they bite, often resulting in red, itchy spots on the skin. Some people may even be allergic to mosquito bites and can experience severe allergic reactions, such as skin swelling and difficulty breathing.
Scientists also note that the blood-sucking by mosquitoes can cause some blood vessels to rupture, leading to blood spilling into the surrounding area, creating “blood pools” where mosquitoes feast to their heart’s content.
Mosquitoes are vectors for diseases such as malaria, dengue fever, and the Zika virus. When mosquitoes bite individuals infected with these pathogens, they carry the pathogens into their own bodies and then transmit the diseases by biting others. This is why mosquitoes are among the leading culprits in spreading many illnesses.
