What is the capillaries main function?

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

I hope this helped

They connect the artrieoles and venules to create uninterrupted blood flow through the body

Dis correct. the rest of the answers are definitely wrong.without the basic needs like food, shelter and love , one will remain trapped in trying to fulfil these needs first which means putting food on the table and struggling to pay bills. it is impossible to achieve self actualization when without the basic needs which is the base.
