Arterial end of capillaries has a _____ hydrostatic pressure

Answer 5

High

So much fluid that colloids have less of a pull

Question 8

Fluid shift from the plasma to the interstitial space is due to…

Answer 8

High venous hydrostatic pressure
Low plasma oncotic pressure
High interstitial oncotic pressure

Question 9

Fluid shift from the interstitial space to the plasma could be due to…

Answer 9

Low venous hydrostatic pressure (dehydrated)
High plasma oncotic pressure (diabetes, too much salt, urea)
Low interstitial oncotic pressure

Question 10

Reasons for increased plasma oncotic pressure

Answer 10

Therapeutically administered (Mannitol, albumin, hypertonic solutions), hyperglycemia

Question 11

Therapeutic reasons for increased interstitial hydrostatic pressure

Answer 11

Elastic stockings, ted hose

Question 12

Reasons for high venous hydrostatic pressure (plasma –> interstitial space)

Question 13

Reasons for decreased plasma oncotic pressure (plasma –> interstitial space)

Answer 13

Insufficient protein intake
Excessive protein loss (nephrotic syndrome)
Deficient protein synthesis (liver disease)

Question 14

Increased interstitial oncotic pressure could be due to…

Answer 14

Trauma
Burns
?

Question 15

Local effects of plasma –> interstitial space

Answer 15
