DA-LTEBlood is flowing through a bundle of hollow fiber tubes that are each 50 µm in diameter. Thereare 10,000 tubes in the bundle. The hollow fiber tube length is 12 cm and the pressure dropacross each tube is found to be 250 mmHg. The hematocrit of the blood is 0.40. Estimate theblood flow rate for these conditions in each tube.

Blood is the most important fluid in the body and it contributes about 8% (approximately) of the…

A person’s blood pressure is measured at 118/78 and the person’s peripheral pulse is 72. Which of the following statements is correct? Group of answer choices The person’s pulse pressure is 40 mm Hg The person’s MAP is 98 mm Hg The person’s MAP is 66 mm Hg The person’s pulse was measured at the heart
As blood flows from the aorta to the arteries, arterioles, and capillaries and through the venous circulation, it encounters various resistances to flow, which results in pressure drops. Using the table, calculate the resistance for an artery and a capillary. (Note: The viscosity of the blood is 3.5 × 10-3 Pa-s.)
A patient's blood pressure is 130/80 mmHg. What is the value of this patient's pulse pressure ? Group of answer choices 50 mmHg 130 mmHg 80 mmHg
A woman weighing 75 kg is given 10 mg in Evan's Blue dye intravenously. Ten minutes later a blood sample was obtained from another vein and colorimetric analysis of the plasma shows 0.4 mg% of the dye. Assume that the administered dye was evenly distributed in the plasma compartment by the end of the 10 min and that no dye was lost from the plasma during this period. A. Calculate the woman's plasma volume. B. If the woman's hematocrit is 0.40, what is her total blood volume?
Given: Capillaries are where the magic of gas diffusion happens. Capillaries are approximately 5-10 µm in diameter. Let’s pick an average value of 7.5 µm. A normal value of the diameter of an aortic artery is 15 mm. a. What would the Reynolds number be for blood in each vessel?
Give the relative abundance of the nine different cells( as mentioned below) in one cubic centimeter of blood sample. a. The human erythrocytes b. Granulocytes 1. neutrophil 2. eosinophil 3. basophils c.agranulocytes 1. Lymphocytes 2. Monocytes 3 platelets 4. Frog erythrocytes 5. Frog thrombocytes
Calculate the hematocrit of a female patient using the following information:The height of the whole body is 80mm, and the height of the RBC's is 28mm. How is her hematocrit value as compared to the hematocrit normal value of adult femal?
Measuring a-vO2 difference is risky because Select 2 correct answer(s) Arteries have low pressure Venous blood has to be measured from the anatomic "mixing chamber" Venous blood has to be measured from the femoral vein Arteries have high pressure
Hemostasis is a quick and localized sequence (cascade) of events that helps to prevent a hemorrhage from occurring when a blood vessel is damaged. Hemostasis involves – amongst other things – the formation of a platelet plug. Describe the three steps involved in the formation of a platelet plug. What complication may arise if a platelet plug (thrombus) were to detach and travel through the circulatory system? How does Aspirin help prevent a thrombus from occurring?
Kate’s systolic blood pressure is 115 and diastolic is 72. Her pulse pressure is 47. True or False
