What part of the blood plasma has antibodies associated with the immune system? - AnswerGlobulins
,How many times more viscous than water is blood? - Answer4.5-5.5
____________ is the total molar concentration of dissolved particles in 1 L of solution due to transfer of
nutrients and wastes between the blood & tissue fluids - AnswerOsmolarity
Functions of blood include: - AnswerRegulation of body temperature, immunity, water balance, pH

What is DIC? - AnswerDisseminated Intravascular Coagulation- a condition in which clots form in small
vessels blocking or restricting blood flow. This uses up platelets and can cause excessive bleeding if injury
occurs.
What component of blood prevents inappropiate coagulation? - AnswerPlatelet repulsion such as
thrombin dilution and natural anticoagulants such as antithrombin and heparin
What is the function of the pericardium? - AnswerDouble walled membranous sac that allows heart to
beat without friction and resists excessive expansion
List the flow of blood through the heart: - AnswerFrom body (IVC/SVC), right atrium, tricuspid, right
ventricle, pulmonary semilunar valve, lungs, pulmonary veins, left atrium, bicuspid, left ventricle, aorta,
to body
Describe how valve mechanics allow flow and prevent backflow of blood - AnswerEnsure one-way blood
flow and are anchored to heart wall by tendinous chords (chordae tenindeae)
List the flow through the cardiac conduction system: - AnswerSA)Sinoatrial node, (AV)atrioventricular
node, AV(atrioventricular) bundle, R/L bundle branches, Purkinje fibers
What determines cardiac rhythm? - AnswerSA node is the pacemaker and determines heart rate, AV
node can take over if SA node fails and regulates SA rhythm
What is cardiac output? - AnswerThe amount ejected by each ventricle each minute CO=Heart
ratexStroke volume
