If the heart becomes damaged or weakened, then the circulatory system will not function well, which will affect all other body systems (Option C).

  • The heart is a fundamental organ that forms part ofthe circulatory system.

  • This system (circulatory system) consists of blood, blood vessels (i.e., veins, arteries, capillaries), and the heart, which work together to carry out oxygen and nutrients to all body cells.

  • The heart is an organ responsible for pumping blood through these vessels to all cells of the body.

In conclusion, if the heart becomes damaged or weakened, then the circulatory system will not function well, which will affect all other body systems (Option C).
