Adaptive Immunity - (ANSWER)The body's ability to recognize and defend itself against distinct invaders
and their products
5 attributes of adaptive immunity - (ANSWER)Specificity, inducibility, clonality, Unresponsiveness to self,
memory
Specificity - (ANSWER)Ability to look for a very specific molecular shape to act against
Inducibility - (ANSWER)The ability to activate against a specific pathogen
Clonality - (ANSWER)The ability to make a clone/copy of itself to help fight a specific type of cell
Unresponsiveness to Self - (ANSWER)The ability that allows us not harm ourselves/own body cells
Memory - (ANSWER)Ability to, if ever a specific pathogen was encountered again, to make a quicker
immune response due to already having been exposed
Leukocytes - (ANSWER)Types of white blood cells involved in Adaptive Immunity
The smallest of white blood cells
Large nucleus and thin rim of cytoplasm `
B lymphocytes cell maturation
T lymphocytes cell maturation - (ANSWER)B cell - mature in the bone marrow
T cell - mature in the thymus
Lymphatic System - (ANSWER)A body system similar to the circulatory system without the flow of red
blood cells

tissues are screened for foreign antigens. Composed of lymphatic vessels and lymphatic cells, tissues,
and organs
Humoral and Cell Mediated Immune Responses - (ANSWER)The types of Adaptive Immune Responses
Humoral Immune Responses - (ANSWER)Type of response with Activated B cells produce antibodies
Cell Mediated Responses - (ANSWER)Type of response that involves activated T cells
Deals with intercellular pathogens
Circulatory System - (ANSWER)Lymphatic cells and vessels are intertwined/connected to what other
body system?
Lymph - (ANSWER)Liquid with similar composition to blood plasma
Fluid leaked from blood vessels into surrounding tissues
Is flowed through body and returned to the heart
Red bone marrow, Thymus - (ANSWER)Primary Lymphoid Organs
Lymph nodes, spleen, tonsils, MALT - (ANSWER)Secondary Lymphoid Organs
Mucosa-Associated Lymphatic Tissue - (ANSWER)What does MALT stand for?
MALT - (ANSWER)Consists of organs like the appendix, lymphatic tissue of respiratory tract, vagina,
urinary bladder, mammary glands, and Peyer's patch in small intestine wall
Muscle Contraction - (ANSWER)Body action that helps keep fluid moving along the lymphatic system

Infection - (ANSWER)Lymph node swelling indicates.....
Germinal centers of Lymph nodes - (ANSWER)A lot of B cell replication occurs here
Medulla region of Lymph nodes - (ANSWER)Region of the body consisting of veins and arteries
Where lots of foreign particles flow
Lymph nodes - (ANSWER)Thousands of body parts throughout the body that can recognize foreign
particles and determine to let out a response to get rid of them
Antigens - (ANSWER)A particle or molecule that the body recognizes as foreign and worthy of attack
Antigens - (ANSWER)Include various bacterial components as well as proteins of viruses, fungi, and
protozoa. Food and dust can also contain antigenic particles
Antigenic in nature - (ANSWER)Parts of the cell that normal human cells do not contain that enter the
body are considered
Epitope (antigenic determinants) - (ANSWER)Part of an antigen dependent on 3D molecular
shape/region of a particular particle
Epitope - (ANSWER)The part of the antigen that they antibody attaches to
Foreign particles outside the cell - (ANSWER)What produces an exogenous antigen?
inside a cell - (ANSWER)Where can antigens be located that makes them harder to find?
Exogenous - (ANSWER)Antigens located outside of the cell are considered to be

Endogenous - (ANSWER)Antigens located inside and move within the cell are considered to be
Autoantigens - (ANSWER)Normal cell antigens
Important that the body recognizes them as self
Autoimmune diseases - (ANSWER)What happens when our own body cells do not recognize our own
cells/attack our own cells?
Plasma cells - (ANSWER)B cells mature into....?
Plasma cells - (ANSWER)Important for producing antibodies
Arise & mature in red bone marrow
Found primarily in spleen, lymph nodes, and MALT
Small % of B cells circulate in the blood
Up to 500000 - (ANSWER)How many BCR's does a single B cell have?
BCR - (ANSWER)Each B cell has multiple copies of the BCR on its surface
Each B cell generates a single type of BCR
Individual's repertoire of BCRs is capable of recognizing millions of different epitopes
Antigen Binding Sites - (ANSWER)2 Variable regions of the BCR form what?
Complementary to epitopes
1 - (ANSWER)How many epitopes does a single BCR receptor recognize?
