Question

Explain how food circulates in our body

Answer 1

As blood circulates around the body, it picks up oxygen from the lungs, nutrients from the small intestine, and hormones from the endocrine glands, and delivers these to the cells.

Answer 2

Your digestive and circulatory systems are among the large organ systems in your body. Digestive organs pass food through your system, breaking it down and absorbing nutrients so you'll get the benefits, while your circulatory system -- made up of your heart and blood vessels -- transports oxygen and other compounds throughout your body. Your circulatory and digestive systems do not directly convert food into energy, but they process and circulate nutrients so your cells can use them for fuel.
