oxygen and glucose
The circulatory system, which includes the heart, blood vessels, and blood, transports glucose and other substances in the blood to the cells of the body. Blood is pumped by the heart through the blood vessels to reach different parts of the body and deliver essential nutrients like glucose.
Needed substances are carried to the body's cells by RBC's, or red blood cells. Red blood cells contain hemoglobin, a substance that allows proteins to bond to them. However WBC's(white blood cells) provide the body's cells with much needed protection.
White Blood Cells(Leucocytes). They engulf the foreign(harmful) substances in the body through enzymes.
Blood is the fluid that carries nutrients, oxygen, hormones, and other substances to the cells of the body. It also helps remove waste products from cells to be eliminated from the body.

capillaries have walls thin enough to allow the exchange of materials between cells and the blood. Their extensive branching provides a sufficient surface area to pick up and deliver substances to all cells in the body.
