Question

Increased permeability of blood vessels allows movement of what from the blood capillaries into the tissue, which will result in swelling and pain?

a) Red blood cells
b) Platelets
c) White blood cells
d) Plasma proteins

Answer 1

The correct answer is d) Plasma proteins, which move into the tissue from the blood capillaries during an inflammatory response, causing swelling and pain. d) Plasma proteins.

Step-by-step explanation:

Increased permeability of blood vessels during an inflammatory response allows the movement of plasma proteins and other components from the blood capillaries into the tissue. This increased permeability is due to chemical signals released upon tissue injury. These signals cause capillaries to dilate and become more leaky, allowing plasma proteins, such as albumin, white blood cells such as neutrophils and macrophages, and fluid to move into the interstitial tissue spaces. The result of these proteins and fluid leaking into the tissues is swelling, or edema, and pain. Therefore, the correct answer is d) Plasma proteins.
