The pH level of the human blood must be maintained at a pH within 7.35-7.45. Excess acidity or basicity in the blood, brought about by the food we take, would lead to disorder in the metabolic processes; at times, the right amount of oxygen will not be circulated to the tissues. Our natural filter, the kidneys, help preserve the normal pH level of the body. Discuss ways that we can do so as not to overwork our kidneys in order to maintain the pH balance of our body.

Which of the following statements about pH is (are) true: pH is a measure of free hydrogen ion concentration none of these are true both of these are true An increase in hydrogen ion concentration means a decrease in pH scale units

When you vomit once, blood pH does not change to a biologically significant degree. When you vomit repeatedly, your blood pH is still likely to stay within the normal range how is homeostasis maintained.

Use a calculation based on the pH partition model to determine the likelihood that a weakly acidic drug of pKa= 3.0 will be absorbed passively from the stomach (pH = 2.3) or from the small intestine (pH = 5.0). The pH of the blood is 7.4 .

Viscosity of a fluid is related to the internal friction of movement within the fluid, along with the friction between the fluid and the wall of the vessel.   Viscosity has implications on the flow rate through a tube or vessel.  Viscosity of plasma is about 1.8-times the viscosity of water at 37°C and this is due primarily to the protein content in the plasma. Whole blood (including the blood cells) has a viscosity ~ 3-times the viscosity of water.  There is a condition called polycythemia that is characterized by excessive blood cell production and these individuals have blood viscosity up to 8 times that of water.  How might the heart (a) or the vasculature (b) adapt to this problem to normalize blood flow rate? Be specific about the variables that could be modified and compare the magnitude of change that would be required in these variables.   c) Why would the adaptation via the vasculature be the major mechanisms that would likely take place in these patients?
