Answer 1

Digestive, Endocrine, Circulatory

Answer 2

The process of breaking down food and absorbing nutrients involves multiple body systems. 1. The **digestive system** is responsible for both the mechanical and chemical breakdown of food, starting with salivary enzymes that break down starches and gastrointestinal enzymes that process various food components.2. The **endocrine system** releases hormones that signal the release of digestive enzymes.3. The **circulatory system** transports absorbed nutrients from the small intestine to cells throughout the body.The most directly interacting body systems in these processes are the digestive, endocrine, and circulatory systems.
