Answer 2

Hey mate , here is the answer...ツ

✤Deep sea divers carry oxygen cylinders in their backs so as to receive oxygen. If they do not carry them,they do not get oxygen and there is a chance even to die. They must need oxygen to breathe and live. So,they must carry them as they go deep into the sea.

✤The alveoli are thin-walled and richly supplied with a network of blood vessels to facilitate the exchange of gases between blood and the air-filled in alveoli. They have a balloon-like structure that provides maximum surface area for exchange of gases.

✤Muscle cells can release pyruvate and lactate (from glycolysis) into the blood. This pyruvate and lactate is taken up and converted to glucose by liver cells.

❥Hope this helps you....ツ
