The other day, I learned the physiological mechanics of a mosquito bite.
Some of you might have seen the same animated video that I did as it makes the rounds on Facebook. I learned that it’s really all about the mosquito’s saliva (ick) – it acts as both an anesthetic and anticoagulant, allowing the female to get the blood she needs (what a wonderful provider God is!….I think…).
Then the video concluded with an interesting point: the actual swelling and itching of a mosquito bite isn’t directly caused by the saliva. It’s caused by the body’s immune response to the bite. The saliva is an allergen, which triggers antibodies to attack the foreign intrusion, and that causes the swelling and itching we’re all familiar with as we writhe around upon the grassy ground, scratching like gangbusters.
I was reminded of other bodily responses. A lot of symptoms we experience to various problems aren’t actually caused by the problem: they’re the result of our body fighting the virus or the infection or whatever.
We would not want to live without physical pain.
