The blood cells must move through the capillaries in a single file line because the diameter of the capillary is only slightly larger than the diameter of the blood cells - there isn't room for two blood cells to go through side by side.
it won't clot
if your blood cells clot, it will cause a heart attack
Capillaries
False
Both red and white blood cells pass through the capillaries.
Capillaries. They're so small that red blood cells are sometimes forced to travel single-file.
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.
So that white and red blood cells can pass through the capillaries
They are blood vessels
through arterioles
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.
Red blood cells are highly specialized for oxygen transport. They lack a nucleus and instead, contain many copies of hemoglobin. Red Blood cells move single file through the capillaries
Red blood cells move in single file in the capillaries. This movement maximizes diffusion.
Capillaries are so small that when you look at blood flowing through them under a microscope, the cells have to pass through in single file. They are like a web.
