While prepping to start an internship at the local hospital you learn that systemic arteries have diameters greater than 10 mm. You know that blood carries charged particles, and you start to wonder how strong a uniform magnetic field would have to be in order to detect the flow of these charges in the blood with a voltmeter that can measure voltage differences down to a millivolt. You assume that the blood flows at a rate of about 10 cm/s

Expert Solution

We know that, Q = r⁴P / 8 L

A v = r⁴P / 8 L

v = r⁴P / 8 L A

v = r⁴P / 8 L ( r²)

v = r²P / 8 L

where, r = radius = 5 x 10^-3 m

P = average blood pressure = 1.32 x 10⁴ Pa

= viscosity of blood = 4 x 10^-3 Pa.s

v = blood flows speed = 10 cm/s = 0.1 m/s

inserting all these values in above eq,

(0.1 m/s) = (3.14) (5 x 10^-3 m)² (1.32 x 10⁴ Pa) / 8 (4 x 10^-3 Pa.s) L

L = (103.6 x 10^-6 Pa.m²) / (3.2 Pa.m)

L = 32.3 x 10^-6 m

L = 3.23 x 10^-5 m

You have been chosen for a very competitive undergraduate clinical internship at St. Visintainer’s Hospital and Metabolic Clinic working with Dr. Saccharo, an expert in enzyme deficiency disorders related to glycolysis. Before your first day Dr. Saccharo has asked that you review the reactions of glycolysis and the concept of isoenzymes. Recall that isoenzymes are groups of enzymes that catalyze the same reaction in that they use the same reactants to product the same products. They may have different genes,...

1) While working as a scribe at a local hospital, you are witness to a 48-year-old male who arrived in the emergency suite who was unresponsive. Prior to becoming comatose, he reported to a friend he was experiencing mental confusion, nausea, abdominal pain and was breathing rapidly. Upon examination, he demonstrates he is breathing rapidly and has a blood pressure of 150/95. Lab tests show his blood glucose to be 450 mg/dL, he also has elevated serum potassium, magnesium and...
