IMMUNE SYSTEM

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 phagocytic…

The body’s immune response comprises innate immunity and adaptive immunity. Virulence is the capacity of a pathogen to cause disease          BOTH statements are FALSE       BOTH statements are TRUE       FIRST statement is FALSE; SECOND statement is TRUE       FIRST statement is TRUE; SECOND statement is FALSE

6.Statement 1: Dendritic cells are phagocytes with professional antigen-presenting properties. Statement 2: Neutrophils circulate as part of the blood and act as surveillance to detect presence of pathogens. Note: This is a multiple question, choose the correct answer below: Statement 1 is true. Statement 2 is false. Statement 2 is true. Statement 1 is false. Both statements are true. Both statements are false.

List and describe 4 types of innate immunity. Two of your answers should include examples of the body's first line of defense and two should include examples of the body's second line of defense   (2 types for examples of the body's first line of defense 2 types for examples of the body's second line of defense)
