Edema is due to_______________?
Correct answer: B. Decreased albumin conc. in blood
- A. Increased albumin in blood and decreased globin
- B. Decreased albumin conc. in blood
- C. Increased osmotic pressure
- D. None of the above
Explanation
Low blood albumin reduces plasma oncotic pressure, so fluid leaves the intravascular space and accumulates in tissues as edema. Increased osmotic pressure would tend to retain fluid rather than cause edema.
