Step 1: Understand the role of arteries in the cardiovascular system. Arteries are blood vessels that carry blood away from the heart to various parts of the body. They are primarily involved in transporting blood, not in the exchange of substances.
Step 2: Learn about the exchange vessels in the cardiovascular system. The exchange of gases, nutrients, and waste products occurs in capillaries, which are small, thin-walled blood vessels designed for this purpose.
Step 3: Compare the function of arteries and capillaries. Arteries are larger and have thicker walls to withstand high pressure, while capillaries are specialized for exchange due to their thin walls and proximity to tissues.
Step 4: Evaluate the statement provided. The statement 'Arteries are the exchange vessels of the cardiovascular system' is false because arteries are not involved in the exchange process; capillaries are the exchange vessels.
Step 5: Correct the false statement. The corrected statement is: 'Capillaries are the exchange vessels of the cardiovascular system.'

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Arteries

Arteries are blood vessels that carry oxygenated blood away from the heart to the tissues of the body, except for the pulmonary arteries, which carry deoxygenated blood to the lungs. They have thick, elastic walls to withstand high pressure from the heart's pumping action.

Exchange Vessels

Exchange vessels refer to capillaries, which are the smallest blood vessels in the cardiovascular system. They facilitate the exchange of oxygen, carbon dioxide, nutrients, and waste products between blood and surrounding tissues through their thin walls.
