What is the typical range for viscosity of the blood?

Blood is a non-Newtonian, shear thinning fluid with thixotropic and viscoelastic properties. Many cardiovascular handbooks consider blood viscosity values between 3.5 and 5.5 cP to be normal.

What is the driving force for blood flow Physioex?

pressure gradient
What is the driving force for blood flow? You correctly answered: pressure gradient.

What is the greatest effect on blood flow?

There are three primary factors that determine the resistance to blood flow within a single vessel: vessel diameter (or radius), vessel length, and viscosity of the blood. Of these three factors, the most important quantitatively and physiologically is vessel diameter.

Which of the following has the greatest effect on blood flow Physioex?

blood vessel radius
Which of the following has the greatest effect on blood flow? You correctly answered: blood vessel radius.

Does blood viscosity affect blood pressure?

According to this equation, a decrease in viscosity causes an increase in cardiac output and opposite this, an increase in viscosity causes a decrease in cardiac output. Therefore, the physiologic compensation of viscosity-related decreased blood flow rate will be an increase in pressure or vasodilation.

How do you increase blood flow rate?

Flow can be calculated by multiplying velocity, the distance moved by an object over time, with cross-sectional area. Within the circulatory system, velocity can be altered by changes in blood pressure, vessel resistance, and blood viscosity.

Which of the following could cause an increase in peripheral resistance in the blood vessel Physioex?

atherosclerosis
Which of the following could cause an increase in peripheral resistance in the blood vessel? You correctly answered: atherosclerosis.

Which blood vessel has the greatest effect on blood pressure?

The pressure is greatest when blood is pumped out of the heart into the arteries. When the heart relaxes between beats (blood is not moving out of the heart), the pressure falls in the arteries.

Which blood vessels have the greatest effect on blood pressure?

Blood vessels include arteries, capillaries, and veins. Arteries carry blood away from the heart and can divide into large and small arteries. Large arteries receive the highest pressure of blood flow and are more thick and elastic to accommodate the high pressures.

What effect would a decreased hematocrit?

What effect would a decreased hematocrit have on blood flow? You correctly answered: decreased viscosity, increased flow.

How do you measure blood flow to the heart?

Doppler ultrasound testing allows doctors to clearly see how blood flows through the heart and blood vessels. It also lets them see and measure obstructions in arteries and measure the degree of narrowing or leakage of heart valves. It may be recommended for patients with atherosclerosis or coronary artery disease.
