The statement "Courtney has a strong heart and lungs so this means she has good cardiovascular strength" is **True**.
Here's why:
1. **Heart and Lungs**: The heart and lungs are vital components of the cardiovascular system. The heart pumps oxygen-rich blood to the body, while the lungs help oxygenate the blood and remove carbon dioxide.
2. **Cardiovascular Strength**: Cardiovascular strength refers to the efficiency of the heart and lungs in delivering oxygen to the muscles during physical activity. If Courtney has a strong heart and lungs, it indicates that her cardiovascular system is in good condition.
3. **Impacts on Overall Health**: Having good cardiovascular strength is beneficial for overall health. It improves endurance, reduces the risk of heart disease, and enhances performance in physical activities.
Therefore, based on the relationship between strong heart and lungs and cardiovascular strength, the statement is true. Having strong heart and lungs is indicative of good cardiovascular strength.
