What color is deoxygenated blood?

Deoxygenated blood is often described as being blue in color due to its appearance when viewed through the skin. This is related to the way light penetrates the skin and reflects off blood vessels. Although deoxygenated blood is actually a dark red color when observed without the skin, the interpretation of it appearing blue is a common misconception based on visual perception rather than the true color.

Understanding the properties of blood and its components is essential for those in the dental field, as it also relates to the understanding of overall circulation and oxygen transport in the body. Recognizing these types of blood helps dental professionals appreciate the implications for oral health and systemic conditions, influencing patient care and treatment planning.
