Question 1

edema

Answer 1

• excessive/abn accumulation of fluid in the interstitial space
• fluid comes to IS from blood
• can be life-threatening if it occurs in certain places (brain, lungs, heart)

Question 2

causes of edema

Answer 2

1. increased capillary hydrostatic pressure
2. decreased colloid osmotic pressure
