The tissue lining of the lymphatic capillaries consists of "epithelium."
|
False, endothelium
|
|
The largest lymphatic vessel of the body is the "vena cava."
|
False, thoracic duct
|
|
Before entering its contents into the cardiovascular system, the right lymphatic duct unites with the "right subclavian vein."
|
True
|
|
The lymphatic system is a "one-way" system for fluid.
|
True
|
|
The two major cells of the lymph nodes are the T-lymphocytes and "P-lymphocytes."
|
False, B-lymphocytes
|
|
Those lymph vessels entering the lymph nodes are known as "efferent" lymph vessels.
|
False, afferent
|
|
Within the lymph nodes, lymphocytes are arranged densely within the outer portion of the node called the "medulla."
|
False, cortex
|
|
The lymph nodes serve the body as the site for the production of "antigens."
|
False, antibodies
|
|
The "inguinal" lymph nodes are the lymph nodes found in the neck.
|
False, cervical
|
|
Lymphoid tissue found in the wall of the intestinal tract is called "palatine tonsils."
|
False, Peyer's patches
|
|
The thymus is the body organ in which "B-lymphocytes" are produced.
|
False, T-lymphocytes
|
|
The spleen is located in the upper portion of the abdominal cavity, just "anterior" to the diaphragm.
|
False, posterior
|
|
The fluid derived from blood traveling through the lymphatic vessels is known as "lymph."
|
True
|
|
Lymph sometimes has a milky consistency because of the presence of "proteins."
|
False, fats
|
|
An accumulation of interstitial fluid in the spaces between the cells causes a condition known as "edema."
|
True
|
|
The immune system begins to develop during the third month after "birth."
|
False, conception
|
|
The receptor sites positioned on the cell membrane of B-lymphocytes are "antigen" molecules.
|
False, antibody
|
|
An antigen molecule is usually a large protein or "nucleic acid" molecule.
|
False, polysaccharide
|
|
Antigens are chemical molecules interpreted by the body as being "self."
|
False, nonself
|
|
The immune process begins with phagocytosis of foreign organisms by body cells such as "lymphocytes."
|
False, macrophages
|
|
The immunity imparted to the body by T-lymphocytes is known as "cell-mediated" immunity.
|
True
|
|
After stimulation by antigens, B-lymphocytes become "phagocytic" cells, which are responsible for antibody production.
|
False, plasma
|
|
To prevent the immune process from becoming overactive, the body uses its "helper" T-lymphocytes to slow down the process.
|
False, suppresser
|
|
All antibody molecules are composed of "carbohydrate."
|
False, protein
|
|
The immune system has the capacity to produce a "dozen" different kinds of antibody.
|
False, million
