Document Summary

Learning objectives for heart part 1: the heart is the centre of the cardiovascular system. It is located between the lungs within the mediastinum (medial cavity of the thorax: pericardium: tough connective tissue layer that encloses the heart. It anchors and protects the heart and prevents it from over filling. It consists of outer fibrous pericardium and inner serous pericardium. The serous pericardium has a parietal layer and a visceral layer, pericardial fluid fills the gap between these layers: epicardium is the visceral layer of serous pericardium. The myocardium is composed of cardiac muscle tissue (muscle cells connect via elastin and collagen fibers). The endocardium consists of endothelium and ct; it lines heart chambers. It is continuous with endothelium in vessels leaving the entire heart. Cardiac wall is highly vascularized: ct fibers reinforce myocardium internally and anchor cardiac muscle fibres, some heart anatomy and blood flow, heart has left and right atria and two left and right lower ventricles.
