  1. Cardiovascular System Chapter 6

  2. Cardiovascular System Overview • A “closed” system consisting of the heart and blood vessels. • Arteries – carry blood away from the heart • Veins carry blood towards the heart • Systemic circuit – delivers oxygenated blood to the body tissues and back • Pulmonary circuit – delivers deoxygenated blood to the lungs and back

  3. Lab Activity 6.1 – External Heart AnatomyAnterior View • Left atrium • Pulmonary veins • Right atrium • Superior/inferior vena cavae • Left ventricle • Aorta • Right ventricle • Pulmonary trunk

  4. Lab Activity 6.1 – External Heart AnatomyPosterior View

  5. Lab Activity 6.2 – Internal Heart Anatomy • Atrioventricular valves • Tricuspid • Bicuspid (mitral) • Papillary muscles • Chordae tendineae • Semilunar valves • Pulmonary • Aortic

  6. Lab Activity 6.2 – Internal Heart AnatomyCompare the Features

  7. Lab Activity 6.3 – Circulation of Blood Through the Heart • RAtricuspid valveRV pulmonary valvepulmonary trunk/arteries lungspulmonary veinsLAmitral valveLVaortic valveaortabody systemsSVC/IVCRA
