Verified step by step guidance

Understand the role of the digestive system: The digestive system is responsible for breaking down food into nutrients, which are then absorbed into the bloodstream.

Identify the needs of the muscular system: Muscles require energy in the form of ATP (adenosine triphosphate) to contract and perform work.

Connect the two systems: The nutrients absorbed by the digestive system, such as glucose, amino acids, and fatty acids, are essential for the production of ATP in muscle cells.

Explain the process of energy supply: Once nutrients are absorbed, they are transported to muscle cells where they undergo cellular respiration, a process that converts these nutrients into ATP.

Conclude the relationship: By supplying the necessary nutrients and energy, the digestive system supports the muscular system's ability to contract and function effectively.
