How do I explain the connection between respiration, nutrition, ventilation and circulation in supporting the healthy functioning of the cell?

During respiration process, there is gaseous exchange. Oxygen also burns food so the cells receive nutrition - and this entire process occurs because there is blood circulation throughout the body.

I guess "blood" is the key word. Ventilation implies allowing fresh air to enter the body so fresh air is again used and this oxygenated blood is carried to the cells - it is the breathing process basically

okay. nutrition is needed by an organism for energy needs. so basically the process of acquiring energy sources is nutrition. now different animals need different types of carbon compounds(all foods are carbon based) so respiration is the process in which OXYGEN is acquired from OUTSIDE the body to break down the complex carbon compounds inside the body for fulfilling the energy needs of the cell.
circulation is the TRANSPORTATION of these ENERGY SOURCES and OXYGEN which have to b delivered to each and every cell.
