Respiratory Notes


Respiratory System function 1. to take in oxygen from the air and bring to the circulatory system and cells 2. exhale co2 and water
Respirtation process when oxygen and glucose go through a series of chemical reactions in your cells, much different than breathing
3 products of repiration carbon dioxide, energy, and water
Nose where air comes in through body, warms up air, moistens & filters
Pharynx back of mouth, upper throat, also known as throat
Larynx voice box, 2 folds of connective tissue that streach across the opening produce sound, vibrate when air passes them, contract when you talk
Trachea long tube, covered by epiglottis, reinforced by rings of cartilage, divides into brochi
Brochi divide into bronchiles
Bronchiles enter lungs, divide up even more
Alveoli small air sacs in lungs (300 mil), increase surface space of lungs, allow more air to be inhaled, surrounded by capillaries, gas exchange takes place in alveoli
Cilia tiny hair like things that sweep mucus into the throat
Lungs main organs in the repiratory system
Diaphragm large, dome shaped muscle at base of lungs, expands when breathing, contracts when exhaling
Air 21% air, 78% nitrogen, 1% carbon dioxide, helium and others
