Alveoli are tiny, balloon-like structures at the end of the bronchial tubes within the lungs. They are the terminal parts of the respiratory tree and are primarily involved in gas exchange. Alveoli allow oxygen to enter the blood and carbon dioxide to be expelled from the blood. They have very thin walls that facilitate this gas exchange between the air and the blood in the surrounding capillaries. Alveoli are found exclusively in the lungs. Capillaries are the smallest blood vessels in the body, connecting arteries and veins. They have thin walls composed of a single layer of endothelial cells, which allows for the exchange of nutrients, gases, and waste between the blood and tissues.Capillaries are primarily involved in the exchange of oxygen, carbon dioxide, nutrients, and metabolic waste products between the blood and the cells of the body’s tissues. Capillaries are found throughout the body, surrounding nearly every cell to provide them with vital substances and to remove waste.
