The four valves in the heart
What are the bicuspid, tricuspid, pulmonary, and aortic valves?
SV x HR =
What is CO?
The liquid portion of the blood in which the formed elements are suspended
What is plasma
The lifespan of RBCs
What is 120 days?
The veins that carry oxygenated blood
period of relaxation during which the heart chambers fill with blood
What is diastole?
The most common type of granulocytes
What are neutrophils?
The location where RBCs go at the end of their lifespan to be engulfed by macrophages
What is the spleen?
The location where blood from the right ventricle travels
What are the pulmonary arteries/lungs?
The terms for 1) amount of stretch on the myocardium at the end of diastole, a reflection of venous return
and 2) the force against which the ventricles must contract to eject blood
What is Preload and Afterload?
The hormone that platelet production is mainly controlled
What is thrombopoietin?
The hormone from the kidneys that stimulates RBC production from the stem cells in the bone marrow
What is erythropoiesis?
The node that initiates ventricular contraction
What is the AV node?
The term for the percentage of blood that leaves the heart each time it contracts
What is Ejection Fraction?
The process of RBC formation
What is hematopoiesis?
The majority of proteins in plasma
What is albumin?
The ability of pacemaker cells to create a electrical impulse without being activated by an outside force
What is automaticity?
The law that states that the more more cardiac muscle stretches, the greater its force of contraction, and therefore the greater the stroke volume
What is Frank-Starling's Law?
Extrinsic and intrinsic pathways that converge leading to the formation of a clot
What is the clotting cascade?
an interatrial pathway that initiates depolarization of the left atrium
What is the Bachmann bundle?
