it is the second clinically important blood group with the antigen involved called D antigen
Rh blood group
44
has antigen D and has no anti-D antibodies
Rh-positive
45

46
Rh stands for... it is a protein present on the surface of RBCs not all people have it
rhesus
47
immune system cells that are larger than RBCs these cells retain their nuclei and lack hemoglobin
white blood cells / leukocytes
48
the only complete cell in the blood; that is they contain nuclei and the usual organelles
white blood cells / leukocytes
49
these cells participate in many immune responses some secrete signaling molecules that provoke inflammation, whereas others destroy bacteria, viruses, parasites, tumor cells and some produce antibodies
white blood cells / leukocytes
50
some white blood cells enter the bloodstream, most either wander in body tissues or settle in the __________ __________
lymphatic system
51
these cells are motile using an ameboid movement by putting out irregular cytoplasmic projections
white blood cells / leukocytes
52
ability of white blood cells to leave the blood and enter other tissues WBCs become thin and elongated and slop between or through the cells of blood vessel walls
diapedesis (leaping across)
53
ability of WBCs to locate areas of tissue damage and infection in the body by responding to certain chemicals that diffuse from the damaged cells
chemotaxis
54
it is the accumulation of dead white blood cells and bacteria, along with fluid and cell debris at the site of an infection
pus
55
the two major groups of WBCs
granulocytes: neutrophils, basophils, eosinophils agranulocytes: lymphocytes, monocytes
56
white blood cells with large cytoplasmic granules and lobed nuclei
granulocytes
57
the most numerous WBCs, active phagocytes, number increases rapidly during acute infection
neutrophils
58
kill parasitic worms, releasee chemicals that modulate inflammation and increase during allergy attacks
eosinophils
59
rarest of the WBCs, release histamine which is an inflammatory vasodilator chemical that makes blood vessels leaky and attracts other WBCs to the inflammatory site; and heparin - which prevents clot formation
basophils
60
white blood cells that lack visible cytoplasmic granules
agranulocytes
61
found in lymphatic tissue - B lymphocytes produce antibodies and T lymphocytes are involved in graft rejection, fighting tumor and viruses

68
they are rough disc-shaped with glycoproteins on their surface allowing __________ to attach to other molecules, such as collagen in connective tissue
platelets / thrombocytes
69
platelets prevent __________ ___________ by forming platelet plugs that seal holes in small vessels and promotes the formation and contraction of clots that help seal off larger wounds in the vessels
blood loss
70
the platelets attract plasma proteins called __________ __________, which participate in reaction that ultimately produce a web of protein threads
clotting factors
71
the protein threads produced by clotting factors trap RBCs and platelets, forming a __________ ____________ - a plug of solidified blood
blood clot
72
abnormal increase of platelets
thrombocytosis
73
abnormal decrease of platelets
thrombocytopenia
74
it is the stopping or cessation of bleeding
hemostasis
75
hemostasis involves 3 major phases
vascular spasms platelet plug formation coagulation (blood clotting)
76
it begins when a blood vessel is damaged and connective tissue in the vessel wall is exposed to blood
hemostasis
77
vasoconstriction as the immediate response to a blood vessel injury and chemicals released by the damaged blood vessel cells causes blood vessel spasms the spasms narrow the blood vessel, decreasing blood loss until clotting can occur
vascular spasms
78
a ___________ ___________ is an accumulation of platelets that can seal small breaks in the blood vessels
platelet plug
79
injury to the lining of the vessel exposes collagen fibers then the platelets adhere platelets then releases chemicals that make nearby platelets sticky forming a platelet plug
platelet plug formation
80
a __________ __________ is a network of threadlike protein fibers, called fibrin, that traps blood cells, platelets and fluids
blood clot
81
clotting factors present in plasma and released by injured cells interact with calcium to form thrombin, the enzyme that joins fibrinogen proteins with fibrin
blood clotting or coagulation
82
__________ ___________ forms a mesh that traps red blood cells and platelets, forming the blood clot
fibrin proteins
83
the blood clot is usually dissolved within a few days after clot formation
clot dissolution
84
process that dissolves blood (clot)
fibrinolysis
85
the enzyme __________ hydrolyzes or breaks fibrin and dissolves that clot it becomes part of the clot as it forms
plasmin
86
it is activated by many substances including thrombin and lysosomal enzymes released from damaged tissues
plasmin
87
blood cell formation occurring in the red bone marrow
hematopoiesis
88
stem cells where the formed elements of the blood are derived and are located in the bone marrow these are precursor cells capable of dividing to produce daughter cells that can differentiate into various types of blood cells
hemocytoblasts
89
chemical signals that regulate the development of the different types of formed elements
erythropoietin colony stimulating factors (CSFs) and interleukins thrombopoietin
90
hormone secreted by the kidneys that stimulate stem cells at the red bone marrow to develop into red blood cells
erythropoietin
91
prompts the red bone marrow to develop into leukocytes but also enhance the ability of mature leukocytes to protect the body
colony stimulating factors (CSFs) and interleukins
92
is a glycoprotein hormone produced by the liver and kidney which regulates the production of platelets at the red bone marrow
