The aorta, the largest artery in the body (in diameter), carries oxygen-rich blood away from the heart as it begins the systemic blood flow circuit throughout the body. Owing to the fact that the aorta connects directly to the heart, the blood pressure (BP) inside the aorta is very high. As blood travels further from the heart, the BP gradually decreases. For example, the BP in the aorta is higher than in the brachial artery; the BP in the brachial artery is greater than in the antecubital artery; the BP in the antecubital artery is greater than in the radial artery. Based on the understanding that walls of the aorta are subjected to extreme outward pressure, hypothesize the order of specific tissue types one would expect to find in the aorta (from deep to superficial) and explain your rationale
