Which of the following is NOT a function of the carotid artery?

• A. Carrying oxygen-rich blood
• B. Regulating blood flow
• C. Transporting nutrients to tissues
• D. Supplying blood to the brain

Answer: (C)

The carotid artery plays a vital role in the circulatory system, and its primary functions include carrying oxygen-rich blood to the head and brain, regulating blood flow, and supplying adequate blood to the brain. Each of these functions is essential for maintaining oxygenation and nutrient delivery to the brain, which is crucial for its proper functioning. When considering the functions of the carotid artery, it is important to differentiate between the roles it plays and those typically associated with other types of blood vessels. The carotid artery is primarily responsible for transporting oxygen-rich blood and ensuring that the brain receives the necessary supply for its metabolic needs. Regulating blood flow is also a critical function of the carotid artery, as it adapts to the requirements of the brain during various activities. Transporting nutrients to tissues, while fundamental to the circulatory system, is generally a function linked more closely to smaller vessels, such as capillaries, rather than the carotid artery itself. The carotid artery does not directly transport nutrients; instead, it is responsible for the delivery of oxygenated blood, which indirectly supplies nutrients as well, but its primary designation does not include this function. Thus, understanding the specific roles of the carotid artery clarifies why transporting nutrients to tissues is
