The [[Breathing System ]] is an [[Organ System|organ system]], that includes [[lung]]s , used to [[Absorb (biology)|absorb]] [[Oxygen]] into the [[blood]] and remove [[Carbon Dioxide]] from the [[blood]].

[[Oxygen]] is transferred into the [[blood]] while [[Carbon Dioxide]] in the [[blood]] is transferred into the [[alveolus]]. ===Breathing===: To [[Breathing|breath]] the [[lung]]s must be able to take in new [[air]] and release the old [[air]].: When the [[lung]]s take in [[air]] this is called [[Inhale|inhalation]].: When the lungs get rid of old air this is called [[Exhale|exhalation]]. {| class="wikitable"|-|[[File:Breathing.png|center|400px]]|-| style="height:20px; width:400px; text-align:center;" |: To [[inhale]] the [[diaphragm]] [[contract]]s and goes down while the [[Intercostal Muscle|intercostal muscles]] [[contract]] pulling the [[Rib Cage|ribs]] upwards and outwards.: To [[exhale]] the [[diaphragm]] relaxes and goes up while the [[Intercostal Muscle|intercostal muscles]] relax allowing the [[Rib Cage|ribs]] to go down and inward.
