- he classic signs of inflammation are that the tissue becomes hot, swollen, and painful, and the coloration of the overlying skin may change color slightly or significantly. Explain in detail the microscopic levels that occur that cause these macroscopic signs to appear (hot, swollen, painful, color change). How are these microscopic changes beneficial in terms of fighting infection? Are there any other microscopic events that are not immediately reflected in the macroscopic signs of inflammation?a 24-year-old who has recently returned from a skiing vacation in the Canadian Rockies, presents to his physician with a swollen left knee. There is a decrease in range of motion and pain upon walking. Physical examination reveals a painful left knee which is swollen. X-ray of the knee reveals the accumulation of fluid and subsequent synovial fluid analysis indicates lymphocytes but a lack of neutrophils. Please discuss whether this knee injury is acute or chronic inflammation and what mediators were likely to be involved in this inflammation.A histological specimen of spleen shows a vessel with a wall consisting of endothelium and subendothelial layer, median membrane is absent, exterior membrane inosculates with the layers of spleen connective tissue.
