Is it true that a strong heart helps nutrients and oxygen reach all parts of the body?

The statement that a strong heart helps nutrients and oxygen reach all parts of the body is indeed accurate. The heart is a vital organ that functions as a pump, circulating blood throughout the body. When the heart is strong, it can efficiently pump oxygen-rich blood and essential nutrients to tissues and organs, supporting their functions and overall health.

A strong heart typically reflects good cardiovascular fitness, which involves the ability to perform physical activities and manage stress. This strength is essential for maintaining proper circulation, which is critical for delivering not just oxygen, but also hormones, antibodies, and other vital substances needed for cellular function.

In contrast, the other options suggest conditions under which this might not apply, such as indicating that a strong heart is only necessary for specific groups, which ignores the fundamental role of the heart in all individuals' health regardless of their physical condition or athletic status. In simpler terms, while physical condition can affect heart strength, the basic principle holds true for everyone—the heart plays a crucial role in nutrient and oxygen distribution in the body.
