Name: ashley wible Exercise 11: Blood Analysis: Activity 2: Erythrocyte Sedimentation Rate Lab Report Pre-lab Quiz Results You scored 33% by answering 1 out of 3 questions correctly. 1. The erythrocyte sedimentation rate (ESR) Your answer : a. measures the settling of red blood cells (RBCs) in a sample of whole blood during one minute. Correct answer: c. is increased whenever fibrinogen and immunoglobulins cause the RBCs to clump together, stack up, and form a column. 2. The ESR cannot be used to follow the progression of which of the following diseases? Your answer : c. rheumatoid arthritis Correct answer: d. gingivitis 3. The ESR can be used to evaluate a patient with You correctly answered: e. all of the above. 10/26/14†¦show more content†¦Why do you think that it has this effect? Your answer: there was a lower than normal sediment rate.The sickle cell shape of RBC does not let them settle. 2. How did the sedimentation rate for the menstruating female (sample 2) compare with the sedimentation rate for the healthy individual (sample 1)? Why do you think this occurs? Your answer: the menstruating females sediment rate was15, this is an elevated sedimentation rate indicating that she has anemia.This is probably a result of the menstrating process. 3. How did the sedimentation rate for the individual with angina pectoris (sample 6) compare with the sedimentation rate for the healthy individual (sample 1)? Why? How well did the results compare with your prediction? Your answer: They were the same. I was wrong when i guessed that it would be lower. 4. What effect does iron-deficiency anemia (sample 4) have on the sedimentation rate? Your answer: Iron-deficiency anemia resulted in a higher than normal sedimentation rate of 30 5. Compare the sedimentation rate for the individual suffering a myocardial infarction (sample 5) with the sedimentation rate for the individual with angina pectoris (sample 6). Explain how you might use this data to monitor heart conditions. Your answer: a person with angina pectoris has a normal sedimenatation rate while a person with myocardial infarction has a high sedmenation rate of 40. you might use thise data to see changes inShow MoreRelatedThe Membrane And The Cell Membrane1217 Words   |  5 Pagesto a lower pressure. This is not selective because the amount of what will pass through is completely dependent on the pressure gradient. Blood cells and proteins are examples of solutes that are too big to pass through the pores (Marieb, Smith PEx-11). Active transport is when energy is required to move a substance across the membrane. It is used whenever substances are too big to pass through pores. The reason this process requires energy is due to the fact that the substance must move againstRead MorePhysioex 61639 Words   |  7 PagesExplain why the larger waves seen on the oscilloscope represent ventricular contraction. The ventricular contraction is when the blood is sent through the whole body as opposed to the atrial contraction that sends the blood to the heart and lungs. 2) Explain why the amplitude of the wave did not change when you increased the frequency of the stimulation. (Hint: relate your response to the refractory period of the cardiac action potential) How well did the results compare with your prediction?

Circle the correct term. A passive process, diffusion / osmosis is the movement of solute molecules from an area of greater concentration to an area of lesser concentration. 2. A solution surrounding a cell is hypertonic if: a. it contains fewer nonpenetrating solute particles than the interior of the cell. b. it containsRead MoreExercise 5 Cardiovascular Dynamics5750 Words   |  23 PagesEXERCISE 5 Cardiovascular Dynamics O B J E C T I V E S 1.
