Ch. 20 The Lymphatic System and Immunity
Chapter 20, Problem 20.4a
Fill in the blanks: Nonspecific immunity is also known as_____. Specific immunity is also known as_____. Specific immunity has the capacity for immunological ______ .
Verified step by step guidance1
Identify the two main types of immunity: nonspecific and specific.
Nonspecific immunity is also known as innate immunity, which provides general defense against pathogens.
Specific immunity is also known as adaptive immunity, which targets specific pathogens with a tailored response.
Adaptive immunity has the capacity for immunological memory, allowing the immune system to respond more efficiently upon re-exposure to the same pathogen.
Fill in the blanks with the appropriate terms: 'innate', 'adaptive', and 'memory'.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Nonspecific Immunity
Nonspecific immunity, also known as innate immunity, refers to the body's first line of defense against pathogens. It includes physical barriers like skin and mucous membranes, as well as immune responses that are not tailored to specific pathogens, such as inflammation and the action of phagocytes. This type of immunity provides immediate but general protection against a wide range of invaders.

Introduction to Immunity
Specific Immunity
Specific immunity, also known as adaptive immunity, is characterized by its ability to recognize and remember specific pathogens. This type of immunity involves lymphocytes, such as B cells and T cells, which are activated upon exposure to a particular antigen. Specific immunity develops over time and provides long-lasting protection through memory cells that respond more effectively upon subsequent exposures.

Immunological Memory
Immunological memory is the ability of the immune system to remember past infections and respond more rapidly and effectively upon re-exposure to the same pathogen. This is a key feature of specific immunity, where memory B and T cells are formed after the initial exposure to an antigen. This mechanism is the basis for the effectiveness of vaccines, which aim to create a memory response without causing disease.
