What This Insect Did Next Would Make You Itch!

When you look at this insect close up, it might make your skin crawl.

Here at Bullshire Online it certainly gives us the shivers.

We set one of our intrepid reporters on a mission to find out what would happen if one of these insects actually did land on your skin.

What they found out would  make you itch.

When female mosquitoes poke their proboscis through your skin so they can suck some of your blood to be later used to make eggs, they inject you with some of their saliva.  This saliva helps them to drink your blood more quickly, because it contains a cocktail of anticoagulants.  Once the female mosquito is full up of your blood or is disturbed, she flies away, leaving some of her saliva behind.  Your body then kicks your immune system in gear as a response to the presence of this saliva.  It produces various antibodies which in turn bind to the antigens in the mosquito’s saliva.  This then triggers the release of histamine.

Histamine is a nitrogen compound that, among other things, triggers an inflammatory response.  It also helps white blood cells and other proteins to engage invaders in your body by making the capillaries of these cells more permeable.  Bottom line, the histamine ends up making the blood vessels near the bite swell up.  This produces a pink, itchy bump where the mosquito poked you.

Fascinating yes?
