Structure of the Heart
The Cardiovascular System
• Function:
• Transports fluids, nutrients, waste products, gases & hormones throughout the body
• Exchange materials between blood, cells and extracellular fluid
• Plays a role in immune response, blood pressure and regulating body temp.
• The heart
• Pericardium
➢ Fibrous pericardium → Parietal pericardium → Pericardial cavity → Visceral
pericardium → Tunica externa (adventitia) → Tunica media → Tunica intima
• Wall
➢ Epicardium → Myocardium → Endocardium
➢ Pectinate muscles: muscular ridges in auricles and right atrial wall
➢ Trabeculae carnae: muscular ridges and columns on inside walls of ventricles

Document Summary
The cardiovascular system: function, transports fluids, nutrients, waste products, gases & hormones throughout the body, exchange materials between blood, cells and extracellular fluid, plays a role in immune response, blood pressure and regulating body temp, the heart, pericardium. Fibrous pericardium parietal pericardium pericardial cavity visceral pericardium tunica externa (adventitia) tunica media tunica intima: wall. Pectinate muscles: muscular ridges in auricles and right atrial wall. Trabeculae carnae: muscular ridges and columns on inside walls of ventricles: nodes. Sinoatrial (sa) node: located in the right atrium of your heart, pace maker. Atrioventricular (av) node: located on the interatrial septum close to tricuspid valve: blood flow. Superior and inferior vena cava right atrium tricuspid valve right ventricle. Pulmonary semilunar valve pulmonary trunk pulmonary artery pulmonary circulation pulmonary vein left atrium bicuspid valve left ventricle . Aortic semilunar valve aorta systemic circulation: blood, plasma. Solutes (ions, nutrients, waste products, gases, regulatory substances: buffy coat.
