The circulatory system, which includes the heart, blood vessels, and blood, mainly distributes nutrients and oxygen throughout the body. The digestive system processes food and extracts nutrients, but it is the circulatory system that delivers those nutrients to the rest of the body. The endocrine system produces hormones, which regulate various bodily functions, but it does not directly distribute nutrients or oxygen. The integumentary system consists of the skin, hair, and nails, and helps protect the body, but it also does not directly distribute nutrients or oxygen.
