surrounding heart
The connective tissue responsible for protecting the heart is the pericardium. This double-walled sac consists of an outer fibrous layer and an inner serous layer, which produces a lubricating fluid to reduce friction during heartbeats. The pericardium not only provides a protective barrier but also helps anchor the heart within the chest cavity.
The chordae tendinae are composed of dense connective tissue called collagen. This collagen tissue provides strength and stability to the chordae tendinae, which are fibrous cords that connect the valves of the heart to the papillary muscles in the ventricles.
The heart needs a combination of cardiac muscle tissue for contraction, nervous tissue to help regulate the heartbeat, and connective tissue to provide structural support. Having only cardiac tissue would limit the heart's ability to function properly and regulate its rhythm efficiently. The different types of tissues work together to ensure effective pumping of blood throughout the body.
The cells in heart tissue, such as cardiomyocytes, are specialized for pumping blood and maintaining the heart's rhythmic contractions. In contrast, cells in bone tissue, such as osteoblasts and osteoclasts, are involved in bone formation, remodeling, and mineralization. Heart tissue cells are primarily involved in contraction and conduction, while bone tissue cells are responsible for maintaining the structural integrity and strength of bones.
The fibrous sac of tissue that encloses the heart is the pericardium. It provides protection for the heart.

Pericardectomy is surgical removal of a portion or all of the tissue surrounding the heart. This tissue is known as the pericardium.

The epicardium is made up of connective tissue that contains blood vessels, lymphatics, and nerves. It serves to protect the heart and provide support for the blood vessels that supply the heart muscle. Additionally, the epicardium is involved in reducing friction between the heart and surrounding structures during heart contractions.
The pericardial fluid acts as a lubricant and reduces friction between the opposing surfaces as the heart beats (contacts). The pericardial fluid is secreted by the pericardial membranes.
Inflammation of the tissue surrounding the heart causes pericarditis ; inflammation of the heart itself causes myocarditis.

Fibrous pericardium and serous pericardium. The serous pericardium is made up of an outer parietal layer that is fused to the fibrous pericardium and an inner visceral layer (aka epicardium) that is a layer of the heart wall and adheres tightly to the heart.
The outermost layer of the pericardial membrane is the fibrous pericardium, which is composed of dense connective tissue and helps protect the heart and anchor it in place within the chest cavity.

Pars fibrosa refers to the fibrous connective tissue component of certain anatomical structures, particularly in the heart. It serves as a supportive framework and is involved in maintaining the integrity of the heart's structure, especially in areas like the cardiac skeleton, which separates the atria from the ventricles. This fibrous tissue plays a crucial role in the electrical conduction system of the heart by providing insulation and ensuring proper coordination of heartbeats.
