4 What happens when your body works very hard?
Ответ:
Ответ:
When your body works very hard, you breathe faster, your heart beats faster, and you sweat.
Краткое пояснение: При интенсивной работе организм усиливает дыхание, сердцебиение и потоотделение.
Пошаговое решение:
- Когда тело работает очень интенсивно, потребность в кислороде увеличивается, поэтому дыхание учащается.
- Сердце начинает биться быстрее, чтобы быстрее доставлять кислород и питательные вещества к мышцам.
- Потоотделение усиливается, чтобы охладить тело и предотвратить перегрев.
Ответ: You breathe faster, your heart beats faster, and you sweat
