Arteries in the circulatory system are responsible for carrying oxygenated blood away from the heart to various tissues and organs throughout the body. These muscular and elastic vessels withstand the high pressure generated by the heart’s pumping action during systole. Arteries branch into smaller arterioles, ensuring the distribution of oxygen and nutrients to cells. The arterial walls help regulate blood flow by contracting and relaxing, contributing to overall blood pressure control. Additionally, arteries play a crucial role in maintaining the circulatory system’s continuous and efficient flow, supporting essential physiological functions and sustaining life.
