Trachea - AKA Windpipe. Moves air from mouth/pharynx to the lungs, Alveoli - Incredibly thin air sacs at the end of lungs where gasses are exchanged into and out of the blood, Cellular Respiration - Reaction that turns oxygen and glucose into ATP energy, Bronchi - 2 branches off of trachea that pass air into/out of both lungs, Bronchioles - Many smaller branches of bronchi that transport air into lungs, Lungs - Stretchy organ that expand to let lots of air in, Larynx - Upper part of trachea that contains vocal cords, Pharynx - Location to moisten and warm air before passage into trachea, Epiglottis - Flap of cartilage that directs air into trachea and food into esophagus, Diaphragm - Curved muscle below chest that expands / contracts to allow air into and out of lungs, Nasal Cavity - Warms and filters air as it enters the body. Hairs/mucus filter out particles and pathogens, Capillaries - Tiniest blood vessels where exchange of gasses occurs with cells, Cutaneous Respiration - Breathing through the skin, Spiracles - Tiny holes gasses move through in grasshoppers' exoskeleton, Gills - Feather-like structures that increase surface area to exchange gas in fish/arthropods, Tracheal Tubes - Structures that receive oxygen in Grasshoppers, Diffusion - The movement of gas from high to low concentration, Surface area - amount of space on a structure gasses can diffuse through,
