Which is NOT true about antibodies?

Which of the following is NOT considered the other first line of defense surface barrier?

What marks a cell as self as opposed to non-self ?

Which is the following is NOT a second line of defense?

Macrophages derive from monocytes that exit the bloodstream and enter into tissue.

Increased permeability of local capillaries; sweep foreign material to lymph vessels to process in lymph nodes.

Complement proteins that coat pathogens to provide handles for phagocyte receptors to bind to.

Humoral immunity acquired by injection of exogenous antibodies from plasma of an immune donor

Which innate internal eliminate variety of infected/cancerous cell by detecting general abnormalities&promote apoptosis?

Identify the correct order of a lymphocyte life cycle.

Which is true about adaptive defense?

Acts on a cluster of neurons in the hypothalamus to raise body temperature

Phagocytosis step __: Phagocyte form pseudopods that engulf the particles, forming a phagosome.

Neutrophils are the big eaters of the phagocytes.

INF used to treat multiple sclerosis

Humoral immunity acquired by antibodies passed from mother to fetus/infant

An incomplete antigen, also called haptens, have immunogenicity, but not reactivity.

Neutrophils follow chemical trail.

Which is true about innate deffense?

Besides their antiviral effects, interferons activate ___ and mobilize ___.

Which is NOT true about adaptive defense?

Which is NOT true regarding the innate defense system?

Which can be considered a first line of defense?

Complement pathway that coats target cells

Lymphocytes are unresponsive to body cells.

A complete antigen has both immunogenicity and reactivity.

Complement pathway that lacks inhibitors on microorganism's surface

Which innate internal is a non specific response to any tissue injury with a chemical alarm?

Fluid with clotting factors & antibodies from blood to tissue spaces which sweeps foreign material to lymphatic vessels

All of the following are considered innate body defenses except ___.

Neutrophils enter blood from bone marrow.

Bacteria that invade surrounding tissues due to slippery coats of evolved enzymes which makes adherence difficult.

Humoral immunity acquired by vaccine; dead or attenuated pathogens

Receptors recognize an antigen & lymphocytes react to one distinct antigen determinant.

Group of plasma proteins that circulate through blood in an inactive state to amplify inflammation

Which is NOT a way that respiratory bursts promotes killing pathogens?

Look for lack-of-self receptors by recognizing certain surface sugars on the target cell:

Why is the secondary immune response faster than the primary immune response?

Phagocytes infiltrate injured sites as an inflammatory response so tissue repairs.

Small proteins secreted by virus infected body cells to protect nearby cells that have not yet been infected.

Phagocytosis step __: Sometimes exocytosis of the vesicle removes indigestible and residual material.

Antiviral proteins block viral reproduction to help protect cells that have not yet been infected.

Complement pathway that binds to specific sugars on a microorganisms surface

Which innate internal is a localized response to infection, but body response is sometimes more widespread?

Neutrophils flatten and squeeze out of capillaries.

Self identification proteins on your cell membranes

Protein forms & stabilizes a hole in the membrane to allow a massive influx of water

Phagocytosis step __: Lysosome fuses with the phagocytic vesicle, forming a phagolysosome.

Humoral immunity acquired by infection from contact with a pathogen

Phagocytosis step __: Toxic compounds and lysosomal enzymes destroy pathogens.

Phagocytosis step __: Phagocyte adheres to pathogens or debris (using receptors).

Receptors⇄pathogens→Engulfed particles» phagosome→Lysosome⇄to»Pahogolysosome→Enzymes destroy→ Sometimes exocytosis

Molecule with two identical halves formed by four polypeptide chains

Inflammation does all of the following except ___.

Neutrophils cling to capillary wall.
