Respiratory System

breathing air moving in and out of the lungs
cellular respiration A reaction that occurs in ALL CELLS to turn glucose into usable energy (ATP). Oxygen and glucose are the reactants. The products are water, carbon dioxide and ENERGY. C6H12O6 + O2 → H2O + CO2 + ENERGY (ATP)
inhale taking air into the lungs, breathing in
exhale pushing air out of the lungs, breathing out
epiglottis a flap at the top of the trachea that prevents food from going down the trachea
trachea also called the windpipe, this is the tube made of cartilage that carries air to your lungs
bronchi the two tubes that split off of the trachea and go to each lung
lungs the two large organs in the chest where gas exchange occurs. used for breathing. They have a spongy structure.
alveoli very tiny air sacs inside the lungs where gas exchange occurs
diaphragm the flat muscle beneath your lungs that contracts and relaxes to help move air in and out of your lungs
cellular waste substances that your cells no longer need, that may build up to toxic levels if they are not removed (includes carbon diooxide, water, salts, and many other substances)
oxygen a respiratory gas needed by cells to make energy
carbon dioxide a waste gas from cells that needs to be removed from the body
BTB an indicator chemical called bromothymol blue that turns yellow in the presence of CO2 in water (because CO2 in water makes a weak acid). It turns back to blue if the CO2 is removed from the water by photosynthesis of water plants.
carbonic acid the acid produced when CO2 is bubbled through water
photosynthesis A reaction that occurs in plant cells (in the chloroplasts) that produces glucose & oxygen from water, ( CO2 & sunlight H2O + CO2 + sunlight → C6H12O6 + O2 )
