- In the disease mononucleosis (“mono”), the spleen enlarges because of increased numbers of phagocytes and other cells. Common signs and symptoms of this disease include pale complexion, a tired feeling, and a lack of energy sometimes to the point of not being able to get out of bed. What might cause these signs and symptoms? (Please include your citation, if there is. Thanks!)The inflammatory lesion which is described as blister with clear fluid inside is called a(n) ___.Three effects of complement activation: (1) inflammation (2) opsonization (3) cytolysis of pathogens. Describe the three effects in at least one complete sentence for each. You should clearly explain *how* complement activation results in the three different effects.

- Label of the lymphatic system asap namehe 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?You are an emergency room physician. Marcus, a 7-year-old boy, has just presented in the ER complaining that (1) his chest hurts, his heart feels funny, and his ankles and knees hurt. His mother says that he has had a fever for the past 24 hours. (2) Upon physical examination, you notice that his ankles and knees are red and swollen, and examination with a stethoscope reveals unusual palpitations (his heart is fluttering). (3) You immediately order an EKG to check for signs of a heart-attack, a CBC blood draw to check for signs of infection, a throat culture to check for presence of Streptococcus, an X-ray of his legs to check for bone fractures or lesions, and a urine sample to check for bacterial contamination. You are using the scientific method to diagnose Marcus. Which of the following statement(s) is your puzzling observation? A) Statement 1 B) Statement 2 and 3 C) Statement 2 D) Statement 3 E) Statement 1 and 2
