In anemia the lower hematocrit results in less oxygen in a given volume of blood. Anemia also decresases the viscosity of the blood. Part A: Use Ohm’s law to determine how anemia would affect flow rate if the pressure remains constant. Refer to the reading or class slides. - The flow rate would increase. - The flow rate would drop Part B: Use Ohm’s law to determine how anemia would affect blood pressure if the flow rate remains constant. - The pressure would increase - The pressure would drop
Homework Answers
As per ohm's law analogy,
resistance to flow = pressure drop / flow rate
so, we can see resistance to flow (viscosity) decreases, the flow rate would increase.

Removing the plasma component of the blood would increase its viscosity. Describe how this increase in blood viscosity would affect the blood flow rate of the giraffe and hence the arterial pressure. What consequence would this have on the giraffe’s cardiovascular system? No more than 150 words. [2 marks].

In hemodynamics, blood flow through the cardiovascular system
can be modeled as an electric circuit in which the blood serves as
electricity, the blood vessels as resistive wires, and the heart as
a battery (see Figure 1).
Figure 1 Cardiovascular circuit model
Ohm’s law states that the voltage drop ΔV across each element,
the current I flowing through it, and its electrical
resistance R are related by ΔV = IR. In a blood vessel, pressure
difference between one vessel and...

The blood pressure at your heart is approximately 100 mm of Hg. As blood is pumped from the left ventricle of your heart, it flows through the aorta, a single large blood vessel with a diameter of about 2.5 cm. The speed of blood flow in the aorta is about 60 cm/s. Any change in pressure as blood flows in the aorta is due to the change in height: the vessel is large enough that viscous drag is not a...

BLOOD AND FLUID QUESTION 1 (0A patient's blood pressure taken at the arm is 120 mmHg systolic and 70 mmHg diastolic. What would you expect the blood pressure (systolic and diastolic pressures) to be at the top of the head given that this point is 40 cm above the measurement point? Remember blood pressure is a gauge pressure and that 1 kPa = 7.5 mmHg. (The density of blood is about 1060 kg/m.) Choose one: a. 89...

Review Constants Periodic Table Air consists mostly of nitrogen (N), with a molecular mass of 28, and oxygen (O2), with a molecular mass of 32. A water molecule (H,O) has molecular mass 18. According to the ideal gas law (N/ V P /KT), dry air at a particular pressure and temperature has the same particle density (number of particles per unit volume) as humidait at the same pressure and temperature. Consequently, humidair, whose low-mass water molecules replace more massive nitrogen...
