WBC chiefly responsible for allergic and antigen response by releasing the chemical histamine?
lysosomes which are small vesicles containing digestive enzymes
Lymphocytes come in three types;
B-lymphocytes, T-lymphocytes, and NK cells; cytotoxic cells that participate in the innate immune response.
which WBC produce antibodies in the humoral immune response?
which WBC participate in the cell-mediated immune response?
WBC that participate in the innate immune response?
NK cells; cytotoxic cells

WBC that are monocytes that have migrated out of the blood stream and into the body tissues?
components of blood?
Plasma, Red Blood Cells, White Blood Cells and platelets
what is Hematocrit?
The percentage of blood volume taken up by RBCs
Functions of blood?
Transportation, regulation and protection
90% water, 9% Proteins 1% minerals.
Where is albumin produced?

Protein, iron, folic acid, and B12
stem cells that give rise to all the formed elements in the blood
What blood cell is the only true cell?
White blood cell because it has a nucleus
what is the function of white blood cells?
phagocytosis and immunity
what part of blood is important for hemostasis?
events of hemostasis are?
Vascular spasms, platelet adhesion, platelet release of chemicals, coagulation
what is the clotting cascade?
clotting factor X, prothrobin (converts to thrombin), fibrinogen.
antithrombin III, heprin,
what are Thrombocytes?
there are 3 steps in platelet plug formation
platelet adhesion, release reaction and platelet aggregation.
Most common anemia
Iron Deficiency Anemia
too many RBC
What is a platelet disorder?
Chemicals involved in clot formation?
tissue factor, prothrombinase, thrombin, fibrinogen, fibrin
Plasmin does what?
breaks down clots
4 heme and 4 globin
kidneys regulate what?
What does Angiotensin II do?
-Increases aldosterone production in adrenal cortex
When is renin secreted?
Low BP, low blood volume, low HCO3. (Metabolic acidosis)
what is pernicious anemia?
most common cause of B12 deficiency
3 conditions that decrease hemoglobin?
anemia, hemorrhage, fluid volume excess
2 Conditions that increase hemoglobin levels
dehydration and polycthemia
what is hemolysis?
Destruction of red blood cells
What enzyme breaks down blood clots?
Universal blood recipient?
type AB blood
what is produced by the hemolysis of RBC?
bilirubin-pigment released by the liver
what is included in the hematological system?

in the red bone marrow, flat and irregular bone
where is ferritin and hemosiderin stored?
liver, spleen, bone marrow and macrophages
the majority of the bodies iron is stored as?
what causes blood pressure?
hydrostatic pressure (created by the heart) forces blood to move through the arteries

superior mesenteric artery
as blood flows through a capillary what causes fluid to leave the capillary?
What causes fluid to enter the capillary?
To determine mean aterial pressure (MAP), cardiac output is multiplied by?
in this system the heart pumps blood out to the lungs from the right ventricle so that gas exchange can occur.
in this system the flow of blood travels through the system of blood vessels that carries blood from the left ventricle of the heart to the tissues of the body and back to the right atrium
the largest percentage of plasma is?
the most important function of albumin in the plasma is?
transport other substances
