5- 10 microns in cross section and the capillary wall thickness is 0.59 - 0.67 micron
Capillaries are alot smaller than arteries.
No. Arteries are the largest blood vessels and capillaries are the smallest.
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.
they are blood vessels that reachout to the cells
they are blood vessels that reachout to the cells
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.
The answer is: c. Capillaries and arteries are similar in size.
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.
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.
Leaky capillaries found in the bone marrow are called sinusoidal capillaries. These specialized capillaries allow larger cells like blood cells to move in and out of the bloodstream more easily due to their larger size and more permeable nature. This facilitates the movement of cells between the bone marrow and blood circulation.
arteries are the biggest and capilleries are small,but veins are the same size range with arteries
