Googles not doing it. Blood is carried through our veins but it’s also all over at once like when cut happens and that’s what give us our warmth, colour, nutrients etc. all over
I’m having trouble understanding how this blood is “all over” evenly spread.
The question is do we have free blood that not in veins and arteries? It’s seeming to me like we do???
How does blood “pool” and swell like a foot or a hand but not enlarge the veins and arteries if that’s where it’s carried?
Am I confusing myself?
EDIT!!! Y’all made that made that make so much more sense. So do capalaries end at where your pores begin? Like why you have blood in a popped pimple?

The answer is capillaries my friend. Blood gets pumped all around your body from the heart and to get all its goodness into the tissues and organs it has to pass through tiny tiny blood vessels called capillaries. They are so thin that they can allow passage of the goodness (and passage out of waste). Think of arteries and veins like highways and main roads, and capillaries like the millions of residential streets that allow you to actually get where you want to go.
