Makes it stronger · Exercise makes the heart pump more, and like other muscles, this makes it stronger over time.
A balanced meal with fruit, vegetables, and grains · A balanced meal has the nutrients and energy your body needs to work and grow.
True · Tobacco smoke harms the lungs and makes it harder for them to work well.
It pumps more blood to the muscles · Muscles need more oxygen during exercise, so the heart beats faster to send them more blood.
An apple and a handful of nuts · Fruit and nuts give you nutrients and lasting energy. Chips, fizzy drinks, and candy give little nutrition.
False · Alcohol affects the liver, brain, and other organs, even in small amounts.
4 · 2 vegetable servings plus 1 protein serving plus 1 grain serving equals 4 servings.
He needs longer, more regular exercise to see real benefits · Short, occasional activity does not challenge the heart enough. Regular exercise over time is what builds strength.
