Artery:An artery is a blood vessel that transports oxygen-rich blood from the heart to all parts of the body. This oxygenated blood gives arteries their bright red color, due to the specific form of hemoglobin present. Arteries function as part of the circulatory system's outbound pathway, effectively transporting blood away from the heart. The term "efferent" is derived from the Latin words "ex," meaning out, and "ferre," meaning to carry, indicating their role in moving blood outward from the heart.Conversely, veins are blood vessels that return oxygen-depleted blood back to the heart. The deoxygenated form of hemoglobin found in venous blood gives it a darker appearance. Veins are essential components of the circulatory system’s return pathway, ensuring blood is brought back to the heart.
