Document Summary
Sketch an o2 equil curve for blood and use it to illustrate the bohr effect. Explain how the bohr effect benefits o2 delivery during exercise. During exercise the metabolic rate goes up, co2 up. Sketch an equil co2 curve for blood, labelling the axes appropriately, add a line representing physically dissolved co2, use the sketch to explain the importance of the red blood cell to blood co2 transport. Bicarbonate group exits the cell in exchange for sodium ion. Reaction of co2 and water and carbamino both in the red line. Not a tidal flow, it is a flow through system. Not as many water breathers uses tidal flow. Like lamprey eel, when unattached, goes through mouth then out gill pouches. When attached, tidal flow in the gill pouches. Expend a lot more energy just to breath. Heat is readily transferred into water compared to air. Especially important in amphibians without lungs or gills.
