Step by step
Solved in 2 steps
- In own word. What are the differences between contagious and communicable diseases? Explain with example?Complement proteins function in defense by _______. a. neutralizing toxins b. enhancing resident bacteria c. promoting inflammation d. forming pores that cause pathogens to disintegrate e. both a and b f. both c and dThe Complement System Kills Microorganisms The complement system supplements the inflammatory response by directly killing microorganisms. Describe the life cycle of complement proteins, from their synthesis in the liver to their activity at the site of an infection.
- The four cardinal signs of inflammation are the direct result of an increase in the amount of ___ in the area of cell damage. fibrinogen lymph macrophages bloodExtravasation has two phases: margination and diapedesis. Describe what happens during these phases in inflammation. In your description include the role of specific adhesion molecules for extravasation.True/False: The C3 convertase amplifies the process of complement activation by generating large amounts of C3b and cleaving large numbers of C5 molecules.
- Inflammation takes part in different diseases. Give a diagram or picture or figure of thatWhich of the following statements are TRUE about the process of inflammation? (Select all that apply) Inflammation can occur with only the innate immune response involved. Leukocytes or white blood cells are found everywhere in the body to carry out inflammation as needed Growth factor from non-skin cells is responsible for the formation of scar tissue in place of the damaged skin cells The increase of warmed blood to a site of injury comes from the hypothalamus Phagocytes engulf invading microbes and dead white blood cells Phagocytosis is used during inflammation to make sure there is no debrisTrue/False: The classical and lectin pathways of complement activation converge at the step of C3 activation. However, the initiating steps of each pathway use protein components and enzymatic mechanisms that share no similarity with each other.
- Adaptive Response Fill in the blanks.. Our specific defense system recognizes and fights autoimmune foreign molecules, or It can protect us antigens against like bacteria or viruses, or abnormal human cells like An allergy is the system's "overreaction" to things like pollen, cancer peanuts, or shellfish. The system can also target healthy pathogens human tissues causing diseases such as rheumatoid arthritis and multiple sclerosis. 11 O Teamwork ToolboxAntibodiesa. prevent antigens from binding together.b. promote phagocytosis.c. inhibit inflammation.d. block complement activation.e. block the function of opsoninsTrue or False 1. In phagocytosis, the digestion of phagocytes is always complete 2. The second line of defense is a specific immune response that responds against a specific type (species or strain) of pathogen. 3. Eosinophils can phagocytize and this is their usual mode of attack. 4. The body’s initial line of defense is made up of chemicals, and processes that work together to prevent pathogens from entering the body in the first place. 5. In general, beta and gamma interferons are present early in viral infections, whereas alpha interferon appears somewhat later in the course of infection. 6. The second line of defense is chiefly composed of external physical barriers to pathogens, especially the skin and mucous membranes. 7. The chemicals involved assist phagocytic cells either by directly attacking pathogens or by enhancing other features of specific resistance. 8. The combination of the barrier function of the dermis including its continual replacement and the presence of…
