The raw materials that are needed by cells are given by two of the body systems, such as the respiratory system and the digestive system. The respiratory system gives oxygen, and the digestive system gives glucose, etc.
Dietary carbohydrates, lipids, and proteins are absorbed by animals in our bodies. These dietary products are macromolecules that are broken down by our digestive system.
After proper digestion, cells get glucose from carbohydrates, small lipid chains from macro lipid molecules, etc. These are essential for the energy production of the cell. For a complete breakdown of glucose, oxygen is required.
Cells utilise oxygen for cellular respiration. Respiration is the process by which oxygen enters the body. In the absence of oxygen, the proper oxidation of glucose doesn't take place, and proper energy can't be produced.
Hence, the two important body systems are the digestive system and the respiratory system, which provide raw materials for the energy production of cells.
