You'll find the little diagram showing you where the pulmonary vein and the pulmonary artery are on page eleven, page eleven if you want to refer to it  right, if you want to look at it in a closer detail tonight that's fine and if you want to see what I'm saying now in a diagrammatic form look on page thirteen  now if you look at that you'll see some, the blue vein blood vessels it's coming out of the right hand side of the heart and if you look at the direction of the arrows, okay, they're going away from the heart, do you agree with me?
