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
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

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

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
