 (a) Cells become variable in shape, size & getting their specialization for the formation of particular tissue or organ in future foetus. They place themselves at some specific regions in embryo for further organogeny.

Need fully answers with procedure for part C) (parts a and b stated as well. Don't leave part c empty :) will give thumbs to fully explained answers. In the cardiopulmonary bypass procedure shown in Figure 15.12 of Saltzman: c) What flow rate of air into the oxygenator is needed to supply the oxygen taken up by the blood? (Hint: You know the net amount of oxygen that is added to the system from the gas input and gas output from part b. Figure 15.12 also states the partial pressures of oxygen in the air that enters and leaves the system. Continuing to use mass balance (Saltzman chapter 7.3.1) and the system defined in part b, determine the flow rate of air (V_air). Assume the flow rate of air into and out of the system is the same and is constant. The answer should have units of mL/min.) (a) How much O2 (in cm^3 at standard temperature and pressure) is returned to the patient per minute if the blood flow rate is 5 L/min? (Hint: First determine the partial pressure of oxygen in the blood returned to the patient from the cardiopulmonary bypass oxygenator from figure 15.12. This can be converted to oxygen content (in cm^3 of O2 per mL of blood) using figure 7.15. Finally, use the specified flow rate to complete the problem. The answer should have units of cm^3/minute) (b) To return the amount of O2 to the body that you calculated in part a, how much O2 must be transferred to the blood per minute? (Hint: You should use the concepts of mass balance from chapter 7 to solve this problem. In particular, start with Saltzman equation 7.1. Recall that the concept of mass balance requires you to define a system, so think about how to do that for this problem. Your solution will be in terms of cm^3/minute. If you define the system properly, the rate at which oxygen enters the system (i.e. VO2) must be sufficient to maintain equilibrium. You need to determine how much O2 enters the system (from one or more sources), how much O2 leaves the system (from one or more sources), how much O2 is generated or consumed by the system (if any), and whether there is an overall accumulation of O2 in the system. You will need to refer to figure 15.12) Blood from central veins and coronary suction Venous reservoir Cold water pO2 40 mmHg PCO2 45 mmHg Pump Gas input pO2 713 mmHg PCO2 0 mmHg pH2O 47 mmHg Gas output pO2 675 mmHg PCO2 30 mmHg pH2O 47 mmHg Oxygenator Treated blood returned to patient pO2 150 mmHg PCO2 40 mmHg Pump
