S/s during 1st stage of the inflammatory response (local infection):

A. Redness, heat, swelling
B. Fever, malaise, headache
C. Pus formation, increased pain
D. Decreased sensation, blisters, itching

Answer 1

The first stage of the inflammatory response is characterized by redness, heat, swelling, and pain. This response is triggered by the release of chemical mediators and leads to increased blood flow and recruitment of immune cells.

Step-by-step explanation:

The first stage of the inflammatory response is characterized by redness, heat, swelling, and pain. These signs are caused by increased blood flow, known as vasodilation, to the site of infection. The release of chemical mediators, such as histamine, triggers the dilation of blood vessels and the recruitment of immune cells, which leads to inflammation. Inflammation is a protective response to localize and eliminate the infection.
