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
under normal operation our bodies have the perfect amount of blood in system to provide oxygen and nutrients to all cells. We do not have an emergency reservoir or secret stash of blood.
on a microsocopic level the components of blood are always dying; so our bodies are also making replacements….this leaves a balanced system not a net positive or negative.
under unusual circumstances inflammation, fatty deposits, gravity can make certain spots on our body (usually hands and feet) much harder for the blood to be pumped back towards the heart.
when damaged blood can escape the normal pathways and form a bruse
