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?
In: Biology
You’re leaving out the capillaries. The arteries pump blood out into the body, and then they connect to tiny capillaries that go everywhere. The other end of the capillaries connect to the veins. From there it’s back to the heart and lungs to start the cycle again.
No pools, (that’s what a bruise is) just tiny tubes that let things pass through into and out of the adjacent cells.
