Humoral immunity is mediated by which cells?

B cells.

36

The specific source of antibodies is

Plasma cell.

37

A gamma-globinemia will seriously impair

Antibody production.

38

The heavy chains of an immunoglobulin differ by having more

Amino acids.

39

AIDS is caused by viruses that specifically invade

T cells.

40

Purified protein derivative is used to screen for

Tuberculosis.

The walls of lymphatic vessels are similar to those of cardiovascular

Veins.

44

Lymphatic trunk that drains the upper limb is the

Subclavian trunk.

45

Lymphatic capillaries are able to receive cellular debris and foreign particles because of the structure of their

Flap like valves.

46

What traits characterize antigens?

Antigens may be proteins, polysaccharides, glycolipids, or glycoproteins that stimulate an immune response.

47

Which of the following molecules is NOT generally produced by T cells and macrophages?

Tissue thromboplastin.

48

B cells activated when it encounters an antigen that matches its B cell

Receptors and receives cytokines from helper T cells.

49

Antibodies interact with antigens in all of these ways except

Releasing interferon.
