What do arteries primarily carry?

Oxygen to the cells
Nutrients to the cells
Deoxygenated blood
Both A and B

The correct answer is: Both A and B

Arteries primarily carry oxygen-rich blood away from the heart to the tissues of the body, which is essential for cellular function and energy production. Oxygen is crucial for the metabolic processes that occur within cells, making it fundamental to overall health and well-being. While blood also transports nutrients from the digestive tract to cells, the primary role of arteries is the distribution of oxygen through the bloodstream. This understanding reflects the dual function of arteries in delivering both oxygen and essential nutrients. The term "deoxygenated blood" typically relates to veins, which are responsible for returning blood back to the heart after it has delivered oxygen and collected carbon dioxide and other waste products from the cells. Therefore, recognizing that arteries carry both oxygenated blood and, in conjunction with oxygen, nutrients, aligns with the key function of this blood vessel type.
