Answer 1

If the heart becomes damaged or weakened, the most appropriate option is:

**The circulatory system will not function well, which will affect all other body systems.**

When the heart is not functioning properly, it cannot pump blood efficiently, leading to reduced oxygen and nutrient supply to various tissues and organs throughout the body. This can have widespread effects on the entire body, including the muscular, nervous, endocrine, digestive, and respiratory systems, among others.
