Human bodys nonspecific second line of defense Assignment

Human bodys nonspecific second line of defense - Assignment Example Immunity is further subdivided into a number of concepts to facilitate the learning for students. The concept chosen here to demonstrate the learning method is human body’s nonspecific second line of defense. This is aimed towards college students and it has been assumed that they have prior understanding of the components of the defense mechanism and know the structure of proteins and WBCs (Glucksman, 2006). In Part 2, using examples and non-examples the concept will be explained in an east-to-grasp manner for students. These examples and non-examples have been chosen to make the concept easier for the students and will be analyzed further to allow students to distinguish between the relevant and irrelevant details based on their relation with critical features to gain clarity of concept. Part 3 will finish the learning exercise with a set of questions aimed at testing the comprehension of the project by the student. They will be different than the examples and non-examples so as to gauge student’s learning. For each short question, the student should be able to give a brief explanation and identify the critical feature involved. Answers have been provided in the Appendix for reference of both students and teachers. Human body’s second line of defense system protects the body against all types of nonspecific infections and antigens. All the features work together to provide the body with the immunity enabling it to survive and fight the foreign invasions. The critical features are: Each critical feature will be further explained in detail. Their function, site of action, and effectiveness in combating the disease will be discussed with the students. Also, the results if second line of defense is compromised will be highlighted. Phagocytic cells are involved in the nonspecific immunity as they attack and ingest the foreign particles, antigens. There are a few types
