A

adjective that relates to the granulocyte precursor cell in bone marrow or spinal cord, or a resemblance to the marrow or spinal cord.

24
Q

Lymphoid Lineage

A

part of the circulatory system, comprising a network of conduits called lymphatic vessels that carry a clear fluid called lymph directionally towards the heart

25
Q

Toll-like Receptors(TLR) vs RLR, NLR

Q

Complement cascade

A

Produce cytokines which increase blood flow to the wound, cause production of adhesin molecules within capillary, and make capillary walls porous

A

life-threatening low blood pressure

36
Q

Disseminated Intravascular Coagulation (DIC)

A

the proteins that control blood clotting become over active

37
Q

Cellular Immunity

A

an immune response that does not involve antibodies but rather involves the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen

38
Q

Perforin

A

the aspect of immunity that is mediated by macromolecules found in extracellular fluids such as secreted antibodies, complement proteins and certain antimicrobial peptides

41
Q

Plasma Cell

A

white blood cells that secrete large volumes of antibodies.

42
Q

Immunoglobulin (antibody)

A

a large Y-shaped protein produced by B cells that is used by the immune system to identify and neutralize foreign objects such as bacteria and viruses
