Why mosquito feeds from a capillary and not from an artery?
Mosquitoes feed from capillaries because the blood flows more slowly in capillaries, making it easier for the mosquito to extract blood. If they were to feed from an artery, the high pressure of the blood flow would make it difficult for the mosquito to access the blood.
When you graze yourself you burst open lots of capillaries even so when you just cut one artery is more serious why?
