5.1 The structure of the heart

Learning objectives Student should understand the following: The gross structure of the human heart and its associated blood vessels in relation to function.

Simplified diagram of the heart Left side Right side

Label this diagram! Aorta Left atrium Left ventricle Pulmonary vein Right atrium Vena cava Right ventricle Pulmonary artery Septum Tricuspid valve Semi-lunar valve Bicuspid valve Papillary muscle Tendon

Double Circulatory System The mammals have a double circulatory system. Blood passes through the heart twice before being pumped to the tissues of the body. The circulatory system can be divided into two: Pulmonary (including the heart and lungs). Systemic (including the heart and the rest of body). This means the heart has 2 sides!

Double Circulatory System

Task Using the text book relate the structure of the following components of the heart to their function: Atrium Ventricle, left and right Bicuspid valve Tricuspid valve Semi-lunar valves Vena cava Pulmonary artery Pulmonary vein Aorta

The structure and function of parts of the heart

Learning objectives Student should understand the following: The gross structure of the human heart and its associated blood vessels in relation to function. Next lesson Heart dissection
