(D) The heart is a complex organ composed of all four primary types of animal tissues:$1$. Epithelial tissue: Forms the lining of the heart chambers (endocardium) and the outer covering (epicardium).$2$. Connective tissue: Present in the valves,fibrous skeleton,and blood vessels of the heart.$3$. Muscular tissue: The cardiac muscle (myocardium) is the primary tissue responsible for the pumping action of the heart.$4$. Neural tissue: The heart has its own intrinsic conduction system (e.g.,$SA$ node,$AV$ node) composed of specialized neural/conductive tissue to regulate heartbeat.Therefore,all four types of tissues are present in the heart.
