Which of these alterations could lead to oedema
A)a fall in capillary blood pressure
B)a fall in the concentration of plasma proteins
C)a dilation of lymph vessels
D)an increase in plasma osmolarity

Question

Quizplus · Accepted Answer

Edema occurs when there is an imbalance in the forces that regulate fluid distribution between the blood vessels and the surrounding tissues. A reduction in the concentration of plasma proteins, for example, due to liver disease or malnutrition, decreases the osmotic pressure within the blood vessels, leading to greater movement of fluid out of the vessels and into the tissues, resulting in edema. Choices A and D have the opposite effect, reducing the movement of fluid out of the vessels and into the tissues, and would therefore not lead to edema. Choice C refers to an increase in lymphatic drainage, which could actually help reduce edema.
