stroke volume
This term is a specialized medical and physiological descriptor used primarily in cardiology and sports science. It describes a specific quantity of fluid displacement per heartbeat, distinguishing it from cardiac output, which is the total volume pumped per minute.
Because it refers to a specific physiological measurement, it is treated as an uncountable noun in clinical contexts. One does not typically refer to multiple stroke volumes unless discussing different experimental trials or distinct patient groups, and even then, the term usually functions as a mass noun representing a metric.
