But then as we go into the arterials the resistance to flow increases, the velocity of the blood flow decreases and the pressure also drops. And that's to ensure that the capillaries don't break as a result of any high pressure and that the flu exchange, the nutrient exchange can take place within our capillaries. Now, the veins connect to our capillaries on the other side. So the capillaries basically take the de oxygenated blood and dump it out into the small veins known as the Venuels. And then we go into small veins and large veins and finally into our vena CaveA. So once the blood travels through the capillaries it enters the Venuels and the veins.
