Immunology

Question 1

Immunity

Answer 1

All mechanisms used by the body as protection against environmental agents that are foreign to the body.

Question 2

Interferons

Answer 2

Proteins made by cells in response to a viral infection, essentially induced a generalize antiviral state in surrounding cells.

Question 3

Phagocytic cells

Answer 3

Type of white blood cell that engulfs and destroys micros type of macrophages

Question 4

Reticuloendothelial System (RES)

Answer 4

Major function is to phagocytize micros and foreign substances in the blood stream and tissues
Widely distributed throughout the body
Also functions to destroy old and imperfect cells

Question 5

Antigen presenting cells (APCs)

Answer 5

Present antigens to T-cells within the adaptive immune system so the T-cells can be activated to generate antigen specific responses.

Question 6

Pathogen associated molecular pathogen (PAMPS)

Answer 6

Set of microbial molecules with conserved motifs that are associated with pathogen infection that serve as ligand for host pattern recognition molecules.

Question 7

Inflammation

Answer 7

Normal immunologic process that restores immune homeostasis.

Most of the cells involved to response are phagocytic cells.

Question 8

Cardinal signs of inflammation

Answer 8

Redness
Edema
Heat
Pain

Question 9

Cytokines

Answer 9

Proteins involved in cell signaling that cannot cross the lipid bilayer

Question 10

Infection

Answer 10

Invasion of the body by harmful micros or parasites causing disease.

Question 11

Four types of infection

Answer 11

Viral
Bacterial
Fungal
Prion

Question 12

Disease

Answer 12

Any harmful deviation from normal structure or functional state of an organism.

Question 13

Latency

Answer 13

occurs when a microbe’s persistence in a host produces host damage without perturbing homeostasis sufficiently to cause clinical symptoms or disease.
