Blood vessel resistance is low in capillaries because there are so many of them. The total cross sectional area is high, resulting in low resistance. Resistance is low in capillaries because they are just 1 endothelial cell layer thick and endothelial cells secrete nitric oxide, a vasodialator. Resistance is low because red blood cells are flexible, allowing them to bend or to stack like plates (rouleaux) in narrow capillaries. Resistance is sort of irrelevant in capillaries because the...
