Bio Exam 3 Flashcards
Name the 3 types phagocytic cells of the innate immune system
Macrophages, Neutrophils, and Dendritic Cells
These phagocytic cells are the first cell line of defense and are found in connective tissue that underlie epithelial tissue throughout the body. (Big Eaters).
macrophages
These phagocytic cells travel to the nearest lymphatic organ to activate adaptive immunity by presenting antigen to the T cells.
dendritic cells
These phagocytic cells only eat a few bacteria before they die but they are more numerous in the blood than any other WBC.They form Pus.
neutrophils
This fluid is derived from tissue fluid and is carried in lymphatic vessels.
lymph
Plasma proteins of innate immunity that can punch holes in bacteria, which kills them, when water rushes in and they explode are called
complement
These proteins of innate immunity are released by virus-infected cells to warn your healthy cells that a virus is near.
interferons
A process of programmed cell death as seen in plasma cells, helper T cells and cytotoxic T cells to control the cell number is called
apoptosis
Adaptive immune cells that mature in the thymus are called
T cells
Adaptive immune cells that are born and mature in the bone marrow.
B cells
immune cells that form memory cells are
B and T cells
these cells become antibody- producing factories
plasma cells
These adaptive immune cells are the Generals in controlling the immune response.
helper T cells
These adaptive immune cells can kill virus-infected cells with perforins and granzymes.
cytotoxic T cells
These cells are infected by HIV-that is how we realized their importance.
helper T cells
These immune need to have the antigen presented to them by dendritic cells before they can mount an immune response.
CD4 and CD8 T cells
Any microorganism that causes disease is called a
pathogen
These cells are filled with vesicles that contain histamine and are responsible for allergic reactions when IgE antibodies bind to their receptors.
mast cells
CD4 T cells will bind to MHC II +Ag on Dendritic Cell
major histocompatibility complex self proteins
CD4 T cells will bind to MHC II +Ag on Dendritic Cell and will form ______________
T helper cells
CD8 T cells will bind to MHC I +Ag on Dendritic Cell and will form
cytotoxic T cells
Name the innate immune cells that have granules filled with histamine and are major players in inflammation, allergies, and asthma
Mast Cells
Name the innate immune cells that kill virus infected and tumor cells with perforins and granzymes
Natural Killer Cells
These innate immune cells are the most numerous of leukocytes (WBCs) and held as a reserve pool in the bone marrow.
Neutrophils
This antibody is found in the body secretions such as breast milk, tears, saliva, gastric juice, and mucous
igA
This antibody is the most predominant antibody in the blood and lymph.
IgG
This antibody is the first antibody made from a vaccine shot or an infection
IgM
This antibody is responsible for allergic reactions
IgE
This antibody is made of 5 Ys joined together
IgM
This is the only antibody that can cross the placenta
IgG
what are 5 types of pathogens
Viruses, Bacteria, Fungi, Parasitic protozoa, and parasite worms
