Concept explainers
To determine:
Does injecting synthetic EPO is differing, in a fundamental way from transfusing red blood cells taken from one’s own blood.
Introduction:
Erythropoietin is a naturally occurring protein hormone and is produced in the body by the kidneys and is used to regulate red blood cell production. Patients suffering from anemia are legally allowed to use this medically.
To determine:
How different training methods affect the fairness of sporting competitions.
Introduction:
The written and unwritten rules are the building blocks of fair play and they should be followed on the field as well as during training also. Fair sports competitions respect sports, and unfair practices must not occur in competitions.

- The erythrocyte sedimentation rate 1. measures the settling of erythrocytes over the period of one minute 2. values are either at 0 or relatively low for healthy individuals 3. is increased when fibrinogen levels become elevated 4. is increased when immunoglobulin levels are lowered 5. is elevated in an individual with angina pectoris Choose from the following: (A) 1, 2, and 3 (B) 2 and 3 (C) 3 and 4 (D) 2, 3, and 4 (E) 2, 3, 4, and 5 (F) 1, 2, 3, 4, and 5arrow_forwardUsing the figure below, provide a reasonable value of hemoglobin saturation (including a unit of measurement) for blood in Jose's left ventricle while he was exercising for one hour. 100 Amount of O2 unloaded in tissue 80 capillaries 60 40 Systemic arterial Systemic venous 20 Po2 Po2 20 40 60 80 100 120 140 Po, (mmHg) Hemoglobin saturation (%)arrow_forwardSelect all answers that applyarrow_forward
- Select the hemoglobin variant(s) that are described by each statement. (a) The variant least likely to cause pathological symptoms. (b) The variant(s) likely to show pl values different from that of HbA on an isoelectric focusing gel. (c) The variant most likely to show a decrease in BPG binding and an increase in the overall affinity of the hemoglobin for oxygen. Answer Bank Hb Milwaukee Hb Cowtown Hb Memphis Hb Philly Hb Providence Hb Bibba HbSarrow_forwardA higher level of hemoglobin in the blood increases the blood’s density. This is the basis for a simple test that can be used to see if a prospective blood donor has a high enough hemoglobin level to donate safely. A drop of blood is placed in a copper sulfate solution, and the time for the drop to sink to the bottom is measured. If this time is too long, the hemoglobin level is toolow. Explain how this test works.arrow_forwardIt is not usually necessary to assess arterial blood gases when diagnosing and treating asthma. However, this information can sometimes be useful in severe asthma attacks. Suppose that a patient had a PO2 of 60mm hg and a PCo2 of 30mm hg when the patient first went to the emergency room. Explain how that could happen.arrow_forward
- What are two advantages and two disadvantages of EHR? What is meaningful use? What are the barriers to implementing an EHR system?arrow_forwardA medical scientist is studying clotting in two patients, one with hemophilia and another without. Identify which patient is which and explain what mechanism is defective in the hemophiliac. A test was also done with a clotting factor added to the blood of patient 2. This factor is often deficient in hemophiliacs and activates other clotting factors to speed clotting. Clotting scores (relative units) are shown below.

What commonly measured cardiovascular parameters might the curves labeled A, B, and C represent? What are the corresponding units for the y-axis of each measure? For your reference, the two labeled curves represent the Pulmonary Capillary Wedge Pressure (PCWP) and the Central Venous Pressure (CVP), both of which are measured in mmHg.arrow_forward
- Calculate the value of colour index of the examined blood if the amount of hemoglobin makes 140g/l, the amount of erythrocytes – 4,2×1012/l. Fulfill the tasks A and B:A) Compare the estimated value with the normal one; write the reference ranges for a healthy adult human.B) Make the conclusion to explain what this value indicates about.arrow_forwardA developing fetus gets oxygen from its mothers blood. Fetal capillaries run through pools of maternal blood in an organ called the placenta. As fetal blood runs through these capillaries, it exchanges substances with the maternal blood around the capillary. The hemoglobin made by a fetus is different than that made after birth. Fetal hemoglobin binds oxygen more strongly at low oxygen levels than normal hemoglobin. How would fetal hemoglobins somewhat higher affinity for oxygen benefit the fetus?arrow_forwardIn a woman's blood analises it was found: hematocrite - 34%, hemoglobin - 90g/l, erythrocytes - 3.5 x 10^12 /l, color parameter -0.77, reticulocytes - 1%, SRE-10 mm/hour. The reasons for erythropoiesis violation the most probable can be the lack of: A. albumins B. globulins C. C vitamine D. iron E. folic acidarrow_forward
