Well, if the question is on just components and functions of the body, it is blood that carries nutrients and oxygen to the cells. If the question is about body systems, the circulatory system (the system for blood circulation through the body) carries nutrients and oxygen to the cells through the blood.
Red blood cells within the blood, within the circulatory system.

Surrounding synovial fluid
interstitial or tissue fluid that surrounds cells.
Cerebral spinal fluid
'''5 functions:''' * takes oxygen and nutrients to every cell * removes carbon dioxide and waste products from every cell * carries hormones from the endocrine glands to different parts of the body * maintains body temperature and fluid levels in the body * prevents infection from invading organism
Blood. However, the delivery is slightly different than the rest of the body. In the CNS the blood filtered by the blood-brain barrier that only allows certain essential nutrients and oxygen to pass through.
Blood it's simple :)

Each and every cell in your body (trillions) has a capillary that goes right by it. These capillaries are part of the blood delivery system. The blood carries nutrients and oxygen to the cells and picks up waste and carbon dioxide.
Surrounding synovial fluid
interstitial or tissue fluid that surrounds cells.
circulatory system is a large organism involving flow of fluid through the tissue and organs allowing the transport and exchange of substances such as nutrients,oxygen and waste products
Cerebral spinal fluid
Blood -> plasma -> extracellular fluid -> cells.
There are open circulatory systems and there are closed circulatory systems. In the open systems found in insects and invertebrates the fluid which carries the blood does not remain within any vessels but rather it bathes the cells of the organs thus transfering the nutrients. In a closed system the blood remains within blood vessels like in the case with humans and the nutrients are diffused out of these vessels to the cells of the organs.
