What type of blood is unoxygenated?

Arterial blood
Capillary blood
Venous blood
Mixed blood

The correct answer is: Venous blood

Venous blood is the type of blood that is unoxygenated. This is because when blood circulates through the body, it delivers oxygen to the tissues and organs and picks up waste products like carbon dioxide. As it returns to the heart, it is considered unoxygenated. The other options, arterial blood, capillary blood, and mixed blood, all contain oxygen. Arteries carry oxygenated blood away from the heart, capillaries exchange oxygen and carbon dioxide between the blood and tissues, and mixed blood is a combination of oxygenated and unoxygenated blood. Therefore, C is the only correct answer.
