- In a woman with body mass 70 kg blood quantity is 4.9 liters; hematocrit is 32%, the quantity of erythrocytes is 3.0*10^12/l, hemoglobin is 105 g/l color parameter is 1.0, the minimum osmotic resistance of erythrocytes is 0.38%NaCl; the maximum osmotic resistance of erythrocytes is 0.34%NaCl Such blood analises testifies first of all about: A. the water excess in the organism B. the lack of water in the organism C. osmotic hemolysis of erythrocytes D. chemical hemolysis of erythrocytes E. the lack of iron in blood plasmaComposition of Blood 1. Determine the physical characteristics of plasma after it centrifuge for 5 minutes? 2. Differentiate the plasma from serum after letting it stand for 15 minutes and then putting it into centrifuge for 5 minutes 3. Microscopic Evaluation of Formed Elements of Blood - Describe the appearance of the erythrocytes, leukocytes and their different types, and the platelets - Discuss the functions of each of the formed elements in the blood and give their relative percentages.DA-LTE Blood is flowing through a bundle of hollow fiber tubes that are each 50 µm in diameter. There are 10,000 tubes in the bundle. The hollow fiber tube length is 12 cm and the pressure drop across each tube is found to be 250 mmHg. The hematocrit of the blood is 0.40. Estimate the blood flow rate for these conditions in each tube.
- Figure 5 shows oxyhemoglobin dissociatlon curves at pH 7.2 and pH 7.4. Which of the following is true at PO2 less than 40 mm Hg? 27. % saturation af haemogiobin 100 pH 7.4 80 60 pH 7.2 40 + 20 10 20 30 40 50 60 70 Po; (mm Hg) Figure 5 A. Hemoglobin retains less O2 at pH 7.4 compared to pH 7.2. B. Hemoglobin retains less O2 at pH 7.2 compared to pH 7.4. C. The release of O2 from hemoglobin is not influenced by the production of CO2. D. At pH 7.2 where CO2 production is less than pH 7.4, hemoglobin releases less O2.Given: RBC count = 8 x 10 12/L Hematocrit = ht of PCV = 38 mm; = ht of WB = 100 mm Hemoglobin = 124 g/L 1. Check the results using the rule of three (expected Hct and Hb range based on the rule of three) 2. Compute for MCV (Mean Corpuscular Volume), Mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC 3. Describe the RBCs expected to be seen on the PBS 4. Are the values reportable? Why?A male patient has presented with the following results for spirometry and plasma Po2. What is your diagnosis? (Use your lecture notes to derive the normal range for these parameters. Also note that usually plasma O2 is determined by saturation percentage, not Po2, but humour me here). Parameter Vital Capacity FEV₁ FVC Arterial Po2 Venous Po2 COPD Value 3560 ml 2110 ml 3120 ml 90 mmHg 35 mmHg Pulmonary fibrosis O Pulmonary oedema O Methemoglobinaemia (causes a leftward shift in the oxygen-haemoglobin dissociation curve)

What are the average hematocrit values (%) at low altitude and then after the subject trained at high altitude for 2 months?The erythrocyte sedimentation rate (heaviness) test of a blood sample is often used as a diagnosis of immune disorders and some other diseases. Assuming that the red blood cells are about a sphere with a diameter of (approximately 5 um) and a density (g/ml 1.125), and the density and viscosity of the plasma in which the red blood cells are settled (Pa.s), (1025 kg/m3 10-3 x 1.5) On arrangement and acceleration m/s2 9.81 Calculate the erythrocyte sedimentation rate (settlement rate).
