Circulatory, Digestive, and Respiratory Systems

Which major body system breaks down food to release nutrients needed for energy production?

• digestive

• muscular

• respiratory

• cardiovascular

Which best describes the circulatory system?

• It protects the major organs of the body.

• It breaks food into nutrients for the body.

• It sends messages to the brain to protect the body.

• It transports oxygen-rich blood throughout the body.

Which best explains the effects of exercise on the respiratory system?

• Exercise increases breathing rate which makes the lungs stronger.

• Exercise increases breathing rate which makes the bones stronger.

• Exercise decreases breathing rate which sends more oxygen to the brain.

• Exercise decreases breathing rate which produces more wastes for the kidneys to process.
