Explanation:

1. Walking, lifting objects, and typing are everyday activities involving the muscular system as they require muscle contraction and movement.
2. The three types of muscles are skeletal (voluntary, attached to bones for movement), smooth (involuntary, found in organs like the stomach for functions like digestion), and cardiac (involuntary, in the heart for pumping blood).
3. The muscular system helps regulate body temperature through shivering (involuntary muscle contractions that generate heat) and through normal muscle - cell metabolism which releases heat.

Answer:

1. Walking, lifting objects, typing.
2. Skeletal: Voluntary, attached to bones for movement; Smooth: Involuntary, in organs for functions like digestion; Cardiac: Involuntary, in heart for pumping blood.
3. Through shivering (involuntary contractions generating heat) and normal muscle - cell metabolism releasing heat.
