Circulatory and Respiratory System Test Review

Reviewing Terms - Circulatory

On the line provided, write the letter of the matching term for each description.

_____1. lower chamber of the heart

_____2. fluid that makes up 55% of blood

_____3. smallest of the blood vessels, with walls only one cell thick

_____4. fluid portion of the circulatory system, pumped by the heart through

blood vessels

_____5. large blood vessel that carries blood from the heart to the body

_____6. upper chamber of the heart that receives the blood

_____7. cell fragment in the blood that aids in clotting

_____8. small group of cardiac muscle cells that sets the pace for the heart

_____9. blood vessel that carries blood from the body back to the heart

_____10. network of vessels that collects and returns the fluids that leak from the

circulatory system

_____11. pathway of the circulatory system in which blood travels between the

heart and lungs

_____12. force of blood on the walls of the arteries

_____13. iron-containing protein that enhances the ability of red blood cells to absorb

oxygen

_____14. type of blood cell that serves as the oxygen carrier in the blood

_____15. blood cell that guards against infection, fights parasites, and attacks

bacteria; leukocyte

_____16. pathway of the circulatory system in which the left side of the heart

pumps oxygen-rich blood throughout the body

_____17. substance produced during clotting that helps to stop the flow of

Blood form a wound

_____18. flap of tissue that prevents the backflow of blood between the atria and the

ventricles

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 Terms - Respiratory

On the line provided, write the letter of the matching term. Each choice can be used once, more than once, or not at all.

_____1. main passageway to the lungs

_____2. muscle that controls breathing as it contracts and relaxes

_____3. flap of tissue that prevents food from entering the trachea

_____4. structure into which air enters after leaving the pharynx

_____5. tube through which air travels from the trachea to the lungs

_____6. passageway from the mouth and nose to the rest of the respiratory system

_____7. dome-shaped muscle that separates the chest cavity from the abdominal cavity

_____8. part of the respiratory system where the vocal cords are located

_____9. structure whose common name is the windpipe

_____10. small air passageways found inside the lungs

_____11. small air sac that is surrounded by a network of capillaries where gas exchange

takes place

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.

Reviewing Skills

19. Complete the graphic organizer to show the path that air travels during inhalation.

20. Write the name of the labeled structure.
