BIPN 102 – Spring 2010 Ni Mo Week 3: Handout #3 nmo@ucsd.edu Material Covered: Lectures 6, 7 OH: Friday 10-11am PC East CO 2  Transport CO 2 exist in 3 forms as they are transported throughout blood. List them and give their approximate percentages. 1. Dissolved CO 2  = 7% 2. Carbaminohemoglobin (Hb-CO2) = 23% 3. Bicarbonate = 70% In the systemic capillaries at tissues, systemic vein, and pulmonary artery : - Type of blood: [ venous /arterial] (circle one) - CO 2 = _ _ pH = _ _ affinity for O 2 = _ _ affinity for CO 2 - HCO 3 - will [enter/ leave ] RBC and therefore plasma [Cl - ] will [increase/ decrease ] In the pulmonary capillaries at lungs, pulmonary vein, and systemic artery     :   - Type of blood: [venous/ arterial ] (circle one) - CO 2 = _ _ pH = _ _ affinity for O 2 = _ _ affinity for CO 2 - HCO 3 - will [ enter /leave] RBC and therefore plasma [Cl - ] will [ increase /decrease] Diagram the pathway, reactions, and ion movements that CO 2 undergoes in the pulmonary vein . (I can’t find the diagram, as you can see, so I’ll list out the stuff) In pulmonary vein, bicarbonate will enter the RBC in exchange for a Cl -  ion, and undergo  the following reaction: HCO3- + H +     H 2 CO 3    H 2 O + CO 2 CO
