Answer 1

Answer:

1.  The accumulation of lactic acid causes muscle cramps. We get relief from cramps after a hot water bath or a massage. Hot water bath or massage improves circulation of blood. As a result, the supply of oxygen to the muscle cells increases.

2. After a physical activity, we take deep breathes and inhale more oxygen. As a result, more oxygen is supplied to our cells and the process of breakdown of food speeds up. Due to this, more energy is released and we tend to feel hungry.

Answer 2

Answer:

Q1) Explain why we get relief from cramps after a hot water bath or a massage?

Solution:-

We get relief from cramps after a hot water bath or a massage, because they improve circulation of blood. As a result, the supply of oxygen to the muscle cells increases. The increase in the supply of oxygen results in the complete oxidation of lactic acid and results in the release of energy, carbon dioxide and water.

Q2) Why do we feel hungry after a heavy exercise or activity?

Solution:-

We feel hungry after a heavy exercise or activity because exercise needs extra energy for which food breaks down very rapidly by faster breathing. This makes us feel hungry.

hope it helps you.
