The smallest blood vessels are called capillaries.
Blood vessels can form new blood vessels, this is called angiogenesis.
The size of blood vessels varies enormously, from a diameter of about 25 mm (1 inch) in the aorta to only 8 μm in the capillaries.
no
it depends upon the size of blood vessels,some are small in size and some are big,in this situation there is alteration of blood flow,so the speed of blood inside the vessels wont be constant
Vasodilation is relaxation of blood vessels leading to increase in lumen size. Vasoconstriction is contraction of blood vessels leading to decrease in lumen size.

Blood cells are much smaller than dust mites. A typical blood cell has a diameter of about 6-8 micrometers, while a dust mite can range in size from about 100 to 300 micrometers. Dust mites are visible to the naked eye, whereas blood cells can only be seen under a microscope.
The typical size of a red blood cell is about 6-8 micrometers in diameter.
