Yes. Capillaries are incredibly tiny so I think it's impossible to count them all.
capillaries carry blood from the heart to the body

It is because your body requires a lot of surface area for diffusion of gasses into the blood.
The smallest blood vessels are the capillaries.
Because if blood pressure in lung capillaries was as high as it is in body capillaries, the hydrostatic pressure caused by this blood pressure would force blood plasma out of the capillaries into intracellular spaces (as is done in body capillaries) or into the alveoli. This would reduce the efficiency of gas exchange.

Capillaries are very thin blood vessels. Oxygen and nutrients and hormones can pass through the walls of the capillaries and reach the body's cells, while red blood cells remain in the capillaries.
Yes, capillaries are nearly everywhere in your body.
Capillaries - they are the smallest vessels that serve as arteries and veins.
The alveoli are surrounded by capillaries that carry carbon dioxide laden blood from the body and return oxygenated blood back to the body.
