If you imagine your right arm as an artery and your left arm as a vein, then clasp your fingers together gently and imagine this is a capillary bed. Arterioles and venules come together in capillary beds and as oxygen is exchanged to surrounding tissue the blood from arteries is passed through the arterioles, through the venules and into the veins to return to the heart.
