Aorta - GCSE Biology Definition

The aorta is the largest artery in the human body and plays a key role in the circulatory system. It originates from the left ventricle of the heart and carries oxygenated blood to other arteries, which then deliver it to the capillaries in tissues and organs throughout the body. The aorta has several parts, including the ascending aorta, aortic arch, and descending aorta, and it branches into smaller arteries that supply different regions. Understanding the structure and function of the aorta in GCSE Biology helps explain how blood is circulated and how the heart supports the body’s needs.
