The correct answer is C. Aorta.
The aorta is the largest artery in the human body. It is a muscular artery that carries oxygen-rich blood from the heart to the rest of the body. The aorta begins at the left ventricle of the heart and ascends through the chest, curving over the right lung to become the aortic arch. The aortic arch then descends through the abdomen, dividing into smaller arteries that supply blood to the organs and tissues of the body.
The radial artery and ulnar artery are two of the main arteries in the forearm. They branch off from the brachial artery and supply blood to the hand and fingers. Arterioles are small arteries that branch off from the larger arteries and supply blood to the capillaries.
The aorta is a vital organ that plays a critical role in the body’s circulatory system. It is important to keep the aorta healthy by maintaining a healthy weight, exercising regularly, and eating a healthy diet.
