If blood is only in arteries and veins, why do you bleed when you get cut? Is a vein/artery getting cut?

Question

It just seems weird that every single square mm can be covered by a vein/artery

Answer 1

Well, there are small capillaries as well, which are probably what you're referring to with a "cut." Blood must be supplied to the entire body because it carries oxygen (among other things) which is vital for EVERY part of the human body to function. Therefore, although these main arteries/veins may not be punctured, the capillaries are. Hope this helps!

Answer 2

Your blood flows through increasingly smaller arteries, until they get to the smallest blood vessals, capillaries. Capillaries are about the width of a singe blood cell, and it's at this level that the oxygen and nutrients carried by your blood is exchanged with waste from your tissues. The wastes and CO2 are returned via your veins to the lungs and liver for elimination.
When you cut your finger you are actually cutting through the capillaries. BTW, if all of your bodies tissues weren't covered by a blood supply the tissues would die.

Answer 3

Yes, every square mm, inch...whatever is full of veins, arteries and capillaries. Ever part of your body has to be constantly fed by your body or it will die.

Answer 4

every cell needs what blood gives.

when you get cut you dont cut major veins/arteries, but probably small capillaries.

Answer 5

yeah, there r capillaries that move the blood to the smallest places, like ur cells, cuz ur veins r too big to reach them.everything on and in u has blood and oxygen flowing to it, or else it would rot and die from gangrene...ew
