Peripheral Vasculature - Nordgren

Question 1

What is it called when there is a net movement of solutes and fluid OUT of the capillary into the interstitial fluid?

Answer 1

Filtration

indicated by positive net pressure gradient

Question 2

What is it called when there is a net movement of solutes and fluid INTO the capillary from the interstitial fluid?

Answer 2

Reabsorption

Indicated by negative net pressure gradient

Question 3

How do you add resistances in a series and how do you add resistances in parallel?

Answer 3

In series: R = sum of individual resistances

In parallel: R = sum of the inverses of the individual resistances

Question 4

Vessels that present the highest resistance to flow?

Answer 4

Arterioles

they are like a dam

Question 5

Fancy word for the elastic nature of veins?

Answer 5

Compliancy (Allows them to undergo large changes in volume to be a volume reservoir)

Question 6

Equation for Mean arterial pressure:

Answer 6

MAP = CO x TPR

cardiac output, total peripheral resistance

Question 7

What happens to the arterial pulse pressure and mean arterial pressure in aging?

Answer 7

Arterial stiffness increases with aging or athersclerosis.

This decreases arterial compliance.
This increases the arterial pulse pressure and increases the mean arterial pressure
