B. Question A 75-year-old man was found unconscious in his bathroom after falling and hitting his head. He survived for several hours but died later in the hospital. An autopsy was performed to determine the exact cause of death. Evidence indicated that the man had suffered two strokes, both due to blocked blood vessels. One had occurred a few weeks earlier; the other had occurred very recently and may have led to the fall. Autopsy findings also indicated that, when the man hit his head, some damage to his brain occurred as well. Based on what you know about inflammation and the cellular structure of the brain, describe what the pathologist found in each of the damaged areas of the brain.
