The video "Blood" discusses the cellular composition of blood. Most numerous are the red blood cells, which are red in color and have no nucleus. They have a bi-concave disk shape, which causes them to appear paler in the middle when looking at them through a microscope. This shape helps them fold onto themselves to fit into narrow capillaries.

Blood pressure is lower in capillaries than in arteries, with much higher friction. How is blood able to flow through such narrow tubes?
