- The air travels into the windpipe - The windpipe divides the air to the two lungs via the bronchial tubes - The lungs oxygenate the blood in the body - Carbon dioxide is filtered out by every cell in the body - The carbon dioxide is carried back to the lungs via the bloodstream - The carbon dioxide is exhaled. What might be the first step of the process?
Ans: Air is taken into the body via the nose or mouth

- The shaft of the turbine spins - Shaft is connected to a generator - The generator uses the spins of the shaft to rotate a rotor - The rotor spins inside the core, which has magnets inside surrounded by wire loops inside - The spinning of the rotor in the core generates electricity - What might be the first step of the process?
Ans: Wind passes the turbines and moves the blades

- The small intestine produces hormones - The hormones cause the pancreas to produce enzymes for digestion - The enzymes travel from the pancreas to the small intestine through tubes - The enzymes help the intestines digest the food - The pancreas produces the hormones insuline and glucagon - The hormones control the amount of sugar in the blood. What might be the first step of the process?
Ans: Food enters the small intestine

- Air enters bronchioles - Bronchioles have tiny air sacs called alveoli - Alveoli surrounded by small blood vessels - Oxygen absorbed by small blood vessels - Vessels deliver oxygen to every cell in the body - Blood brings carbon dioxide back to lungs - Carbon dioxide released when you exhale. What might be the first step of the process?
Ans: Air enters the lungs through bronchial tubes
