lecture 3 - haemorrhage case

Question 1

What is the effect of blood loss on Starling’s Equilibrium?

Answer 1

Reduced hydrostatic pressure in the arterial vessels due to low BP, leading to reduced flow of water to into the interstitium, and increased reabsorption on the venous side.

Question 2

What is the effect of increased venous pressure (e.g. due to heart failure) on Starling’s Equilibrium?

Answer 2

Increased hydrostatic pressure at the venous end of capillary beds reduces reabsorption of water from the interstitium, leading to oedema

Question 3

What is the effect of reduced colloid osmotic pressure in the blood on Starling’s Equilibrium?

Answer 3

Reduced water reabsorption of water from the interstitium on the venous side of capillary beds, leads to oedema.
