arterial blood
Oxygen-rich body fluid
Arterial blood is blood flowing through arteries—the vessels carrying oxygenated blood from the heart to the body's tissues.
It appears bright red due to its high oxygen content, distinguishing it from the darker venous blood returning to the heart.
In medical contexts, arterial blood is drawn for gas analysis to measure oxygen and carbon dioxide levels: The nurse took an arterial blood sample from her wrist.
