The tissue forming a loosely fitting "sack" around the heart is known as the pericardium. The musculature of the heart itself, consisting of "cardiac" muscle fibers, is, in general, referred to as the myocardium.

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!

The loose fitting sac around the heart is lined by the?

The loose-fitting sac around the heart is called the pericardium, which is lined by a membrane known as the serous pericardium. This serous membrane consists of two layers: the visceral layer, which is in contact with the heart, and the parietal layer, which forms the outer wall of the pericardial sac. Between these layers is the pericardial cavity, which contains a small amount of fluid that helps reduce friction during heartbeats.


What are three of tissue that make up the heart?

The heart is primarily composed of three types of tissue: cardiac muscle tissue, connective tissue, and epithelial tissue. Cardiac muscle tissue enables the heart to contract and pump blood effectively. Connective tissue provides structural support and helps maintain the heart's shape, while epithelial tissue lines the heart chambers and forms the endocardium, playing a role in regulating blood flow and preventing clot formation.

Can damage to the left ventricle heal?

it depends on what type of damage. when the heart heals, instead of forming normal heart tissue, it forms non-contractile scar tissue. if you are asking if the heart can get stronger after its been damaged, the answer is yes. the heart has many compensatory mechinisms.
