Lesson: The Nonspecific Immune Response Biology • Third Year of Secondary School

Join Nagwa Classes

Attend live Biology sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to describe how the body prevents pathogen entry and explain ways in which the nonspecific immune system responds to a pathogen invasion.

Lesson Plan

Students will be able to

state the role of the nonspecific immune response as an immediate response to infections,
describe the body’s first line of defense against pathogen entry, including skin, cerumen (ear wax), tears, mucus, saliva, stomach acid, and expulsive reflexes,
recall that phagocytosis and inflammatory responses are examples of the second line of defense,
describe the stages of phagocytosis, including the role of phagocytes and lysosomes,
describe the role of white blood cells and histamine in the inflammatory response.
