Term | Definition |
respiratory system | takes in oxygen from the air you breathe; exchange gases between air and blood |
respiration | process of breathing in oxygen and breathing out carbon dioxide |
oxygen | taken into your blood and used by your entire body |
carbon dioxide | leaves your blood through the thin walls of tiny structures in your lungs; then removed from body |
air | what we breathe; gases around us |
autonomic | carries out the activities of our body without thinking |
contract | moves down allowing more air to enter the lungs |
exhale | take out or remove gases |
expand | when we breath, our lungs get bigger (blow up like a balloon) |
inhale | take in gases |
lungs | main structure of the respiratory system; contain alveoli; oxygen moves from here into the blood and carbon dioxide moves from the blood into the alveoli; carbon dioxide leaves the lungs through nose/mouth |
mouth/nose | when you breath in air (oxygen) may enter your body through one of these two; mostly carbon dioxide exits here |
pharynx | tube extending from the back of the nasal cavity and mouth to the esophagus that is the passage through which air passes to the larynx |
red blood cell | solid part of blood that has hemoglobin which carries oxygen around in the body |
trachea | (wind pipe); air passes from your throat through here before entering your lungs |
vocal cords | stretch over the larynx; when air passes through they begin to vibrate; these vibrations, along with the movements of the tongue and lips produces sounds, enabling speech |
diaphragm | thin sheet lies below the lungs; tighten and relax to make you breath in and out |
alveoli | tiny sacs in the lungs covered with capillaries |
larynx | upper part of the trachea that contains the vocal cords (voice box) |
bronchi | after the trachea, gases travel into these two "branches" (one for each lung) |
bronchioles | lead gases into the lungs (look like roots for a plant) |
