Understanding the Cardiorespiratory System

2. The Heart Pulmonary pump Systemic pump Atria Ventricles Septum Aorta
Coronary arteries

3. The Blood Vessels Arteries - carry blood away from the heart
Capillaries - smallest blood vessels where the oxygen and nutrients are exchanged for carbon dioxide and waste products
Veins - the vessels that carry blood back to the heart

4. The Respiratory System
Diaphragm
Trachea
Bronchi
Bronchioles
Alveoli

5. Aerobic & Anaerobic Activity
Aerobic activities help improve cardiorespiratory fitness - walking, jogging, running, cycling, swimming, dancing, etc.
Anaerobic activities which involve sudden, intensive, explosive muscle contractions can also play a role in cardiorespiratory fitness - sprinting and weight lifting

6. Cardiovascular Disease
Coronary artery disease
Atherosclerosis
Stroke

7. Prevention of Cardiovascular Disease
Uncontrollable Risk Factors
Heredity (Race)
Age
Gender (male or female)

8. Prevention of Cardiovascular Disease
Controllable Risk Factors
Smoking
High Blood Pressure
Unhealthy Cholesterol Levels
Improving your Blood Fat Levels
Lack of Physical Activity
Obesity
Diabetes

9. Understanding the Cardiorespiratory System
Cardiorespiratory fitness is considered the most important aspect of physical fitness.
Cardiorespiratory fitness enables you to have more energy, a lower level of body fat and a lower risk of cardiovascular disease.
