Verified step by step guidance1
Understand the function of each type of blood vessel: arteries, arterioles, capillaries, venules, and veins.
Arteries carry blood away from the heart and branch into smaller arterioles.
Arterioles further branch into capillaries, which are the smallest blood vessels.
Capillaries form networks that permeate tissues, allowing for the exchange of nutrients, gases, and waste products with nearly every cell.
Recognize that capillaries are the only vessels that provide direct access to nearly every cell in the body, facilitating this exchange process.
