7. Normal saline solution of 0.9% NaCl (sodium chloride), which most closely matches the cellular liquid in the body. Suppose a pharmacist accidentally mixes a 2.0% NaCl solution to be given through IV to a patient. What would the result be to a patient's red blood cells when given this IV fluid? a. cells would have no change c. cells would shrink and dehydrate b. cells would swell and burst d. none of these are correct 8. An important buffer system in the human body involved carbon dioxide (CO2) and bicarbonate ions (HCO3-) as shown: CO2 + H2O H2CO3 H+ + CO3- If a person becomes excited and exhales large amounts of CO2, how will his or her body's pH be affected? 9. Pair the following terms with their opposite. a. Cranial _____ Deep b. Lateral _____ Ventral c. Dorsal _____ Distal d. Anterior _____ Caudal e. Proximal _____ Medial f. Superficial _____ Posterior g. Superior _____ Inferior 10. Label these planes of the body 11. Identify the following homeostatic mechanisms as either positive (P) or negative feedback (N). _____ blood clotting _____ temperature regulation _____ blood pressure _____ labor 12. Complete the following table on the 4 types of organic molecules. Type of Basic building block Role in the body molecule Carbohydrates Lipids Proteins
