what is the difference between pulmonary circulation & systemic circulation?
pulmonary- exchange of O2 & CO2 in the lungs
systemic- exchange of nutrients & wastes between blood & cells
arteries transport blood ____ from the heart. what are the smaller branches of arteries which control the blood flowing into the capillaries. veins transport blood _____ the heart. what are the smaller branches of veins?
away (deoxygenated); arterioles; towards (oxygenated); venules
the walls of arteries & veins are made up of what three layers?
tunica
>intima
>media
>adventitia/externa
normally the large arteries are highly elastic in order to what with blood flow?
adjust to the changes in blood volume that occur during the cardiac cycle

it carries antibodies & WBC
plasma, RBC, WBC, thrombocytes (platelets)
refers to the proportion of cells in blood & indicates the viscosity of the blood
high _____= dehydrated
low _____=bleeding or increased fluid
hematocrit
_______is the clear yellowish fluid remaining after the
cells have been removed
_______ refers to the fluid & solutes remaining after the cells & fibrinogen have been removed from the plasma’

what is a bio-concave flexible disc that are non-nucleated when mature, contain hemoglobin, & survive 120 days?
erythrocytes (RBC)
the hormone _________ originates from the kidney which stimulates RBC production in the red bone marrow in response to _____(insufficient 02 available in cells). the availability of amino acids, iron, vitamin b12/b6, and folic acid.

yellow
what does a cell do within diapedesis?
they move through the intact capillary walls
what are the actions of neutrophils, basophils, eosinophils, and monocytes?
N- first to respond to any tissue damage & commence phagocytosis
B- release histamine & heparin
E- allergic reactions
M- become macrophages which act as phagocytes
what occurs within hemostasis? what are the 3 steps to achieve this?

clot formation also known as ______. This requires a set of events to prevent this from bleeding. what electrolyte do we need to prevent this?
coagulation
tissue damage occurs – prothrombin– thrombin– fibrinogen– fibrin (trap cells)
calcium
