PhysioEx Lab Report Exercise 11: Blood Analysis Activity 2: Erythrocyte Sedimentation Rate Name: Naja Crothers Date: 24 January 2021 Session ID: session-3dc0ca2c-f889-452e-58ad-18636d8f4d5c

Pre-lab Quiz Results You scored 100% by answering 3 out of 3 questions correctly. 1 The erythrocyte sedimentation rate (ESR) You correctly answered: 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? You correctly answered: gingivitis. 3 The ESR can be used to evaluate a patient with You correctly answered: all of the above.

Experiment Results Predict Question 1 Predict Question: How will the sedimentation rate for sample 6 (individual with angina pectoris) compare with the sedimentation rate for sample 1 (healthy individual)? i https://media.pearsoncmg.com/bc/bc_0media_ap/physioex/10/ex11/act2/

You correctly answered: the settling of RBCs in a vertical, stationary tube of whole blood during one hour. 2 An increase in the ESR is You correctly answered: associated with worsening of anemia. 3 To properly measure the ESR, you need You correctly answered: a 1-hour timer.

Review Sheet Results 1 Describe the effect that sickle cell anemia has on the sedimentation rate (sample 3). Why do you think that it has this effect? Your answer: sickle cell anemia is a blood disorder witnessed by improper folding of hemoglobin when hemoglobin levels are low and affects the oxygen-carrying capacity of an individual. ESR is the time taken for the erythrocytes to settle in a period of 1 hour. Sickle cell shows no impact on ESR because sickle cell anemia alters the shape of the red blood cells and leads to faster clumping of cells and faster settling. 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 sedimentation rate of the menstruating females is higher when compared to a normal healthy individuals. This is because https://media.pearsoncmg.com/bc/bc_0media_ap/physioex/10/ex11/act2/

menstruating females are anemic and they have less amount of iron in the blood and thus, the settling rates are higher. 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: it was the same as well. 4 What effect does iron-deficiency anemia (sample 4) have on the sedimentation rate? Your answer: iron deficiency anemia increases the sedimentation rate. Decreased iron content in the blood increases the setting time as the cells become much lighter. 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: myocardial infarction is the condition witnessed by stopped of blood flow to some parts due to an injured heart muscle. the sedimentation rate of an individual with myocardial infarction9 is much higher when compared to an individual with angina pectoris.Myocardial infarction is a much severe heart condition i https://media.pearsoncmg.com/bc/bc_0media_ap/physioex/10/ex11/act2/

when compared to angina pectoris, severe the heart condition, the greater is the sedimentation rates.
