What does the following phrase refer to?
“the disease or injury that begins a chain of events or physiologic disruption that lead directly and ultimately to the death:
▪ C. After an individual is declared dead by usual clinical criteria (cardiorespiratory arrest) some cells continue to function and may remain alive for hours to days True
