Arterial blood is the oxygenated blood in the circulatory system found in the lungs, the left chambers of the heart, and in the arteries.〔http://www.thefreedictionary.com/arterial+blood〕 It is bright red in color, while venous blood is dark red in color (but looks purple through the transluscent skin). It is the contralateral term to ''venous blood''. Framed in the cardiac cycle, often historically accredited to the Wiggers diagram, arterial blood has just passed through the lungs and is ready to boost oxygen to sustain the peripheral organs. The essential difference between venous and arterial blood is the curve of the oxygen saturation of hemoglobin. The difference in the oxygen content of the blood between the arterial blood and the venous blood is known as the arteriovenous oxygen difference. == See also == * Acidosis * Alkalosis * Arterial blood gas * Chemical equilibrium * pCO2 * pH * pKa 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「arterial blood」の詳細全文を読む スポンサード リンク
