Reviewing Concepts
If the statement is true, write “true.” If it is false, change the underlined word or words to make
the statement true. Write your answer on the line provided.
_________________________19. The human circulatory system consists of the heart, the blood
vessels, and the blood.
_________________________20. Oxygen-rich blood is pumped by the right of the heart through
the lungs.
_________________________21. Blood returning to the heart from systemic circulation is laden
with carbon dioxide.
_________________________22. Valves in the heart ensure that blood moves through the heart
in a two-way direction.
_________________________23. In the circulatory system, the exchange of nutrients and
wastes occurs in the arteries.
_________________________24. Red blood cells are produced in the periosteum.

Reviewing Concepts
Complete each statement by underlining the correct word or phrase in the parenthesis.
12. The function of the respiratory system is to bring about the exchange of oxygen
and (carbon monoxide, carbon dioxide).
13. After they are inhaled, particles are trapped in the mucus layer that coats much of
the respiratory system. Then (cilia, alveoli) sweep the particles away from the
lungs.
14. During inhalation, the diaphragm (relaxes, contracts).

15. The structure labeled A in the diagram above is the (larynx, trachea).
16. Each of the structures labeled B in the diagram leads to (a lung, the heart).
17. The structures labeled C in the diagram finally end in (tiny air sacs, pleural
membranes).
18. A network of (intercostal muscles, capillaries) surrounds each of the structures in
the diagram labeled D.
