1. 5.1 The structure of the heart

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

3. Simplified diagram of the heart Left side Right side

5. 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!
