Respiratory System

respiratory system The body parts that work together to bring air into and push it out of your body.
breathing what your body does when it takes in fresh air, containing oxygen, and lets out the used air
nose and mouth take in and let out air
windpipe the air passage connecting the throat to the lungs
lungs two spongy bags that expand when they fill with air
diaphragm a dome-shaped muscle that separates the chest from the stomach area.
cartilage tough but bendable material. Cartilage makes your windpipe stiff, so your windpipe doesn't collapse when you breathe in.
inhale when you breathe in and your lungs fill with air
exhale when you breathe out and air is forced out of the lungs
breathing rate the number of times you inhale in one minute
larynx also known as the voice box, it is at the top of the windpipe, all the air you breathe passes through it
vocal cords two elastic bands inside the larynx.
bronchial tubes when you inhale, air moves from the windpipe into two bronchial tubes, one going to each lung
air sacs chambers that have very thin walls. They are surrounded by tiny thin-walled blood vessels called capillaries.
cell the basic unit that makes up all living things
respiration the process by which cells use oxygen and give off carbon dioxide
