When cardiac muscle tissue dies in adults, it is replaced with scar tissue composed of dense connective tissue. Explain how scar tissue would affect the function of the cardiac muscle tissue. A. The scar tissue binds the cardiac muscle together more tightly so heart muscle contractions are less vigorous. B. The scar tissue cannot contract so the heart will be weaker. C. The fibers of the dense connective tissue make the heart stronger. D. The dense connective tissue of the scar tissue transmits the electrical signals to other cardiac muscle cells in the heart allowing the signal to skip over the scar tissue.
