Immunology

Question 1

Cell-Mediated Immunity

Answer 1

Involves direct cellular response to invasion as opposed to antibodies
Cytotoxic T-cells wipe out cells that are infected by a virus

Question 2

Humoral Immunity

Answer 2

Immunity involving antibodies

Question 3

Plasma Cell

Answer 3

Cell that produces antibodies and functions in the elimination of any cell containing on its surface the antigen that it has been summoned to kill

Question 4

Antigen

Answer 4

A molecule that is foreign to our bodies and causes our immune system to respond

Question 5

Helper T cells

Answer 5

Assist in the activation of B Cells
Recognize foreign antigen on the surface of phagocytic cells and bind to these cells
They then multiply to produce a bunch of T cells that pump out chemical signals, which cause the B cells to respond

Question 6

Cytotoxic T cells

Answer 6

The main cells involved in cell-mediated immunity

They recognize cells that productive viral antigens and wipe them out.

Question 7

T cells

Answer 7

Mature in the thymus

Two main types: helper T cells and cytotoxic T cells

Question 8

B cells

Answer 8

Mature in the bone marrow

Two main types” plasma cells and memory B cells

Question 9

Phagocytes

Answer 9

Immune cells (macrophages and neutrophils) that use endocytosis to engulf and eliminate foreign invaders

Question 10

Lysozyme

Answer 10

Enzyme that can kill germs before they have a chance to take hold
Present in saliva and tears

Question 11

Nonspecific Immunity

Answer 11

Nonspecific prevention of the entrance of invaders into the body
