Oxygenated blood
Oxygenated Blood
Oxygenated blood (pronunciation: /ɒksɪdʒɪneɪtɪd blʌd/) is blood that has been enriched with oxygen through the process of respiration in the lungs.
Etymology
The term "oxygenated" comes from the Greek word "oxy" meaning sharp, and "genes" meaning born of or produced from. The term "blood" comes from the Old English "blod", which is akin to the Old High German "bluot".
Definition
Oxygenated blood is blood that has passed through the lungs and has had oxygen added to it. This oxygen is then carried by the hemoglobin in the red blood cells to the rest of the body. The oxygenated blood is bright red in color, as opposed to deoxygenated blood, which is a darker red.
