What is the function of the digestive system in metabolism?

Back

The digestive system breaks down food into smaller molecules, such as glucose and amino acids, which are then absorbed into the bloodstream for energy.

How does the circulatory system support metabolism?

Back

The circulatory system transports oxygen and nutrients, like glucose, to cells throughout the body, enabling metabolism and energy production.
