Immune System Overview

These flashcards cover key concepts related to the immune system, focusing on clonal selection, lines of defense, and various immune responses.

Before you are born, your immune system undergoes a \ component that deletes self-recognition cells.

Deletion

The second part of the immune system's development after birth is called \ selection.

Clonal

Autoimmune issues arise when self-recognition cells are not \

deleted

The primary components involved in the immune response include T cells and \ cells.

B

The foreign component recognized by the immune system is known as an \

antigen

The process of producing copies of selected immune cells is referred to as \ selection theory.

clonal

The \ line of defense is nonspecific and attacks anything that enters the body.

second

The parts of the immune system that are born with you and act as first barriers are part of the \ line.

innate

\\ are part of your white blood cells that include basophils, neutrophils, and eosinophils.

Lymphocytes

Skin, oils, and tears are examples of the \ line of defense.

first

the immune response consisting of heat, redness, swelling, and pain is related to

inflammation

Phagocytosis is a process where cells engulf and \ pathogens.

digest

The \\ immune response occurs after the body has previously encountered an antigen.

secondary

During the primary immune response, the first immunoglobulin produced is \\.

IgM

cells present antigens to the immune system to elicit a response.

Dendritic

The function of antibodies that clumps pathogens together is known as \

agglutination

\ factors are small proteins that help protect against infections.

Antimicrobial

Complement proteins work with the immune system to create holes in \

infectious agents

The \\ immune response involves memory cells that allow for faster action on subsequent exposures to the same antigen.

amnestic

The body's plasma circulates nutrients and is part of the \\ system.

circulatory

Helper T cells activate B cells and other T cells, playing a central role in the \ immune response.

adaptive

The most abundant antibody in the body, which can cross the placenta and provides long-term immunity, is \

IgG

Immunity acquired when your body produces its own antibodies in response to an antigen is known as \ immunity.

active

Small, bean-shaped organs that filter lymph and store immune cells are called \ nodes.

lymph

T cells mature in the \, an organ located in the chest behind the sternum.

thymus
