Why capillaries very small in size?
Capillaries are very small in size because they need to have a large surface area so they are able to transport blood all around the body. Blood cells must pass in single file through the capillaries as they are so small.

Capillaries connect what?
Capillaries connect small arteries to small veins. Capillaries are the site of gas exchange.
How do veins arteries and capillaries compared in size within diameter?
arteries are the biggest and capilleries are small,but veins are the same size range with arteries
Is the artery the same size as your vein?
Arteries and veins can be different sizes, because large arteries branch into smaller arteries, which branch into capillaries. These capillaries branch into small veins, which branch into large veins. So yes, they can be (and usually are) the same size if (I am surmising this) they are the same distance from the capillaries.
What are the blood vessles called when you cut your finger?
Typically, they are capillaries. Capillaries are the very small blood vessels that run the exchange between the arteries and veins - essentially facilitating the U-turn from the heart, back to the heart. Capillaries are very small, only allowing a single file of blood cells to pass through them.
What are small blood vessels called?
The answer you are looking for is most likely a "capillary". "Capillaries are the smallest of a body's blood vessels...which connect aterioles and venules, and enable the interchange of water, oxygen, and carbon dioxide, and many other nutrient and waste chemical substances between blood and surrounding tissues."
