How much blood is pumped from each ventricle during the ventricular ejection phase?

A contractile cell with a membrane potential of 0 mV is experiencing the:

 What part of the hemoglobin molecule actually binds the oxygen molecule?

Identify Section A on the model below. 

Place the following parts of the cardiac conduction system in the order in which they transmit the action potential.1) atrioventricular (AV) bundle2) Purkinje fibers3) sinoatrial (SA) node4) right and left bundle branches5) contractile cells of cardiac muscle tissue6) atrioventricular (AV) node

These bind to surface-bound carbohydrate groups on a RBCs and cause them to clump together:

_________ are the least common leukocyte that secrete chemicals in granules to mediate inflammation like _________ an anticoagulant, and __________ an inflammatory chemical.

Which of the following represents the correct sequence when tracing the path of blood from the left AV valve to the body cells?

How do cardiac cells sustain a membrane potential of around 0 mV during the long plateau phase?
