Question 14

Poiseulle’s law formula

Question 15

Resistance to flow, R formula

Question 16

Reynold’s number formula and the laminar/turbulent threshold

Question 17

Two types of flow in microfluidics

Question 18

State the Navier-Stokes equation

Question 19

During exercise, there is an apparent increase in cardiac output despite minimal increase in the MAP, systolic, and diastolic pressure. This is achieved via…

Answer 19

Reduction in pulmonary and systemic resistance by dilation of endothelial smooth muscles

Question 20

Pulse pressure formula

Question 21

During exercise, the pulse pressure tends to increase due to the increase in systolic pressure. This increase in systolic pressure is in turn due to…

Answer 21

increased stroke volume and heart rate

Question 22

In patient with atherosclerosis, pulse pressure is abnormally high because…

Answer 22

atherosclerosis is the accumulation of plaque on the lining of the blood vessels –> reduces elasticity of the thereof –> increased systolic pressure

there may also be a decrease in diastolic pressure due to reduced blood flow in the sclerotized region furthering the systolic-diastolic pressure difference

Question 22

In patient’s with aortic regurgitation associated with damaged aortic valve, the pulse pressure tends to increase due to the increase in systolic pressure. This increase in systolic pressure is in turn due to…

Answer 22

regurgitation abnormally increases volume of strokes increasing systolic pressure in the aorta and increasing pulse pressure
