Respiratory System

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)
