What is the capillaries main function?

Answer 1

Capillaroes are the smallest blood vessels in your body(think of them as super tiny veins), you have them in places like your fingers and toes. The main function of Capillaries is to distribute oxygen and various nutrients throughout the blood stream so that it can reach the lesser tissues. They aslo act as a mini filter by removing "waste" profucts such as caebon dioxide from the bloodstream
