What is a lysosome?

a membrane-bound bag of degrading enzymes within a cell

what is a gene?

a section of DNA that has the code for making a protein

antigen-presenting cells function to

display foreign antigen on their cell surfaces bound to MHC for t-cell recognition

what are neutrophils?

early responders and most active in bacterial infections, the number of neutrophil bands indicate the severity of the infection

Leukocytosis with a "shift to the left" refers to

elevated immature neutrophils

Which clinical finding is most indicative of an acute bacterial infection?

increased (band) neutrophils

Activation of the complement cascade results in (Select all that apply.)

inflammation and chemotaxis

The primary function of eosinophils is to

kill parasitic helminths (worms)

interleukin-1, interleukin-6, and tumor necrosis factor-α are inflammatory cytokines secreted by

macrophages

The mononuclear phagocyte system consists of (Select all that apply.)

monocytes and tissue macrophages, dendritic cells, monocytes from the circulating blood migrate to organs and tissues to become macrophages

Functions of B cells include

synthesizing antibodies

functions of b cells include

synthesizing antibodies

What is the cytosol?

the liquid inside a cell that is not in organelles

What is the function of enzymes?

to facilitate chemical reactions

Passive immunity is provided by

transfer of performed human antibodies, injection of human immune globulin, injection with performed animal antibodies

Active immunity involves

vaccines with dead or altered organisms, active infections

The primary function of kinins is

vasodilation to enhance inflammation

Proteins that are increased in the bloodstream during acute inflammation are called

acute phase proteins: produced in the liver, C-reactive protein and serum amyloid A

proteins are made of

amino acids

What is a vesicle?

an intracellular membrane-bound compartment

What is a vesicle?

an intracellular-membrane bound compartment

Immunity to a specific organism can be determined by

antibody titer

Functions of antibodies include

antigen agglutination, antigen precipitation, opsonization, complement activation

Functions of antibodies include (Select all that apply.)

antigen agglutination, antigen precipitation, opsonization, complement activation

The "classical pathway" for activation of the complement cascade is triggered by

antigen-antibody complexes

The membrane attack complex formed by complement is similar in function to

perforin

A white blood cell can ingest bacteria or cellular debris through the process of:

phagocytosis

Most receptors in cell membranes are made of:

protein

where are proteins synthesized on a cell

ribosomes

Function of t cell include

secreting cytokines, killing antigen-presenting cells, stimulating of b cells, killing virally infected cells

Functions of T cells include (Select all that apply.)

secreting cytokines, killing antigen-presenting cells, stimulating of b cells, killing virally infected cells

Characteristics of complement include (Select all that apply.)

stimulating chemotaxis, lysing target cells, having multiple plasma proteins, enhancing phagocytosis

The spleen is an important defense against infection, because it

filters the blood, macrophages in the blood filter out foreign substances, lymphocytes activated in the spleen can be transported to other lymphoid tissue to fight infection

Activation of the complement cascade results in (Select all that apply.)

inflammation, chemotaxis

Interleukin-1, interleukin-6, and tumor necrosis factor-α are inflammatory cytokines secreted by

macrophages
