Back to moving O 2 (no eq. fig) The design of a closed system close to our hearts (no eq. fig) Most vasculature is like a closed pipe (fig 44.15b) Contrast to capillary structure (44.15a) Capillaries arent really closed (fig 44.16) Seeing osmosis as a force may take some imagination How does this help with gas exchange? Holes in capillaries are called fenestrations (no eq. fig) On to the pump: Low pressure system has single chamber (fig 44-14) Two chambers required for higher pressure (detail of Fig 44.17) Two circuits means higher delivery rate to tissues (fig 44.17) Another phylogeny to appreciate Flow paths through the 2 circuits (fig 44-18) What gets pumped where (fig 44-19) What pressures are generated when (fig 44-20) Relate this figure to what hemoglobin is doing (Fig 44-23)...
