Antibodies attack foreign proteins
all of the above
Which of the following may be a pathogen
all of the above
the major symptoms of inflammation are
all of the above

false
The thymus enlarges throughout childhood and reaches its maximum size at 40-50 years of age
false
a hapten is a very small molecule that can stimulate an immune response by themselves
false
Which of the following characteristics of the stomach enable it to act as a chemical barrier
low pH
T cell activity is remarkable in all of the following except
lungs
Compartments within a lymph node contain dense masses of
lymphocytes
Immune surveillance is provided by which of the following parts of lymph nodes
macrophages and lymphocytes
The upper skin layer is an example of which of the following body defenses against infection
mechanical barrier
Movement of lymph is primarily due to
muscle contraction
T cells and B cells are to be able to recognize foreign proteins because
of the presence of receptor molecules on T cells and B cells which fit the molecules of antigens
B-lymphocytes respond to foreign protein by
producing antibodies or immunoglobulins
Which of the following is not an antigen-presenting cell
red blood cells
An example of an autoimmune disease is
rheumatoid arthritis

right and left subclavian veins
Which of the following diseases has been eliminated by a world wide vaccination program
smallpox
The largest of the organ(s) of the adult lymphatic system is the
spleen
The largest lymph vessel is the
thoracic duct
The Thymus is located in
thorax behind the sternum
Edema can occur in tissue distal to damage to lymphatic tissue
true
Immunity is resistance to particular pathogens or their toxins or metabolic by-products
true
Interferon, a hormone-like peptide produced by lymphocytes and fibroblasts, is an example of a chemical barrier to infection
true
Lymph flows only in one direction, toward the heart
true
Phagocytic cells can leave the bloodstream by squeezing between the cells of blood vessel walls in the process of diapedesis
true
The fact that a given disease may affect humans but not their cats and dogs is an example of species resistance
true
The smallest of the lymph vessels are tubes with closed ends called lymphatic capillaries
true
The structure of the walls of large lymphatic vessels is most similar to the structure of
veins
