Which of the following is NOT involved in the inflammatory response? A. Activation of B cells by cytokines from TH cells. B. Adhesins, which cause phagocytes to adhere to capillary walls. C. Secretion of IL-6, a pyrogen. D. Dilation of capillary walls. E. Secretion of PMNs to the tissues through capillary walls

Option D.

Explanation:

Inflammatory response occurs when there is an injury to body tissues which might be caused by bacteria, trauma or toxins. The affected tissues now secrete chemicals which cause the blood vessels to release fluid thereby causing swellings. The white blood cells secrete chemicals and release into the tissues to protect it from outside pathogens.

Dilation of capillary walls is not involved.

False

Explanation:

Passive transport does move molecules with the gradient but it does not use energy, it does it by itself using diffusion.
