False
T or F. Plasma consists of a variety of dissolved substances and a small amount of water
all of the above
non specific defenses, select one:
a. mechanical barriers
b. fever
c. chemical barriers
d. all of the above
false
T or F. Beta globulins are the parts of plasma that constitute immunoglobulins (antibodies)
blood coagulation
forms the blood clot through a complex series of events that will have the end result of fibrinogen converting into fibrin
a. blood coagulation
b. blood vessel spasm
c. platelet plug formation
blood vessel spasm
smooth muscles of the blood vessels will contract (vasospasm) to lessen the blood loss
a. blood coagulation
b. blood vessel spasm
c. platelet plug formation
platelet plug formation
condition that occurs as blood escapes in the severed blood vessel and the thrombocytes adhere to the edges of the broken blood vessel, collagen in the connective tissue, and to one another. Platelets release a chemical called serotonin to cause vasoconstriction to further reduce blood loss.
a. blood coagulation
b. blood vessel spasm
c. platelet plug formation
all of the above
antibodies can react to antigens in which of the following ways
a. direct attack
b. activation of compliment
c. stimulation of changes to help prevent the spread of pathogens
d.all of the above

the first of the branches of the aorta that carry freshly oxygenated blood and feed the heart
a. left common carotid artery
b. coronary arteries
c. pulmonary arteries
d. bracheocephalic artery
agglutination
direct attack methods include
a. agglutination
b. chemotaxis
c. opsonization
d. lysis

True
B lymphocytes promote antibody immunity
syncytium
mass of merging fibers in heart that act as unit
lymphatic vessels
as the lymphatic capillaries transport lymph away from the tissue, they merge to become
a. lymph nodes
b. lymphatic trunks
c. lymphatic vessels
cytotoxic T cells
blood cell that continually monitor the body's cells recognizing and destroying tumor cells and virus infected cell by boring or cutting a hole into the cell membrane
artificially acquired, active immunity
immunity occuring through the use of vaccines with the person having little or no symptoms
thrombus
clot that forms abnormally in an unbroken blood vessel
agglutination
interaction of proteins on the surface of cells such as erythrocytes with certain antibodies carried in the plasma

b. secrete seratonin
c. secrete toxins and growth inhibiting factors
d. all of the above
True
T or F. Thrombocytes help repair damaged blood vessels by adhearing to the broken edges

the tonsils are masses of lymphoid tissue that contain which of the following
a. erythrocytes
b. leukocytes
c. antigens
d. antibodies
fever
elevated body temperature to make leukocytes more active and vigorous and to conserve zinc and iron from the pathogen
inflammation
a natural response from the body to isolate a region that has been invaded by a potential pathogen until the pathogen are destroyed
phagocytosis
macrophages, neutrophils, and monocytes
chemical barriers
the chemical make up that prevents the pathogen to thrive within the body. Gastric juices in the stomach, lysozyme in the tears, and sebum from the sebaecous glands are examples
mechanical barriers
intact skin and mucous membranes keep most pathogens from the environment from entering the body; first line of defense
