When muscle tissue dies, is it usually replaced by quizlet?

How does the function of scar tissue differ from that of myocardial tissue?

Similar to skeletal muscle tissue, cardiac muscle does not regenerate to a large extent. Dead heart muscle tissue is replaced by scar tissue that cannot contract. As scar tissue builds up, The heart loses its ability to pump blood due to loss of contractility.
