What are Heart Tissue?
The heart is a muscle, and as such has multiple tissues. The main tissue is cardiac muscle cells. These are striated, branched muscle cells held together with intercalated discs. Connective tissue forms a sac around the heart, and epithelial tissue forms blood vessels within the heart. Therefore, the heart contains all four types of tissue. It is mostly muscle tissue. Connective tissue forms a protective sac and holds the heart together, epithelial tissue forms the blood vessels, and nervous tissue carries impulses to and away from the heart. this is all true! ~Trenasian was here!
