We eat food to obtain nutrients and vitamins that our bodies need, and our digestive system extracts these substances. In addition to digestion, respiration or breathing is also part of nutrition by providing oxygen. The circulatory system is essential for nutrition as it transports the nutrients we eat and oxygen we breathe to our organs, bones, brain, and muscles. Our blood contains three types of cells that each perform specific functions. Vitamins are essential nutrients our bodies need. Junk food contains high levels of sugar and fat, and if consumed in excess can accumulate in our bodies, causing weight gain and potential illness.
