3. describe the role of the digestive system in nutrient absorption and its connection to the circulatory…

Brief Explanations:

The digestive system breaks down food into nutrients (like glucose, amino acids). These nutrients are absorbed in the small intestine (mainly) into the bloodstream. The circulatory system then transports these nutrients to cells throughout the body for energy production, growth, and repair. So, the digestive system provides the nutrients, and the circulatory system distributes them.

Answer:

The digestive system breaks down food into absorbable nutrients (e.g., in the small intestine). The circulatory system then transports these nutrients (via blood) to cells for various functions.
