Verified step by step guidance

1. Identify the primary function of each body system mentioned in the options.
2. Understand that the Digestive system is responsible for breaking down food into nutrients that the body can absorb.
3. Recognize that the Excretory system is responsible for removing waste products from the body, including those generated from the digestion process.
4. Consider the roles of the other systems: the Respiratory system is involved in gas exchange, the Circulatory system transports nutrients and gases, the Nervous system controls body functions, the Endocrine system regulates hormones, and the Skeletal and Muscular systems provide structure and movement.
5. Conclude that the Digestive and Excretory systems are the two systems primarily responsible for breaking down food and removing waste, as they directly handle these processes.
