1 Mr. Ulrich Circulatory Review Name: Regents Biology 1. The muscular nature of the walls of ventricles is most closely associated with their function of A) storing blood from the body B) producing red blood cells C) maintaining pressure lower than that in the atria D) forcing blood to the lungs and body Base your answers to questions 4 and 5 on the diagram below which represents a portion of the human circulatory system and on your knowledge of biology. 2. Base your answer to the following question on the diagram below of the human heart and on your knowledge of biology. 4. Which chamber of the heart pumps deoxygenated blood to the lungs A) 1 B) 2 C) 3 D) 4 5. Which chamber of the heart receives oxygenated blood from the lungs? A) 1 B) 2 C) 3 D) 4 A blockage in structure A would directly reduce blood flow to the A) heart B) lungs C) liver D) brain 3. For blood to pass through the heart from the left atrium to the left ventricle, it must first pass through A) an artery B) a valve C) a vein D) a capillary

2 6. In which heart diagram do the arrows correctly represent the path of blood flow? A) C) 8. Veins are blood vessels that A) deliver blood to the cells of the body B) contain striated muscle C) carry blood toward the heart D) readily exchange materials between the blood and body cells B) D) 9. Which transport vessel is correctly paired with its usual function? A) lymph vessels add blood toward the heart B) capillary provides a site for the exchange of materials between the blood and body tissues C) artery filters bacteria and dead cells from the lymph and the blood D) vein produces white blood cells 7. Base your answer to the following question on the diagram of the human heart below and on your knowledge of biology. 10. A pulse can be detected most easily in A) an artery B) a vein C) a capillary D) a lacteal 11. Which statement best describes arteries? A) They have thick walls and transport blood away from the heart. B) They have thick walls and transport blood toward the heart. C) They have thin walls and transport blood away from the heart. D) They have thin walls and transport blood toward the heart. Which sequence correctly represents the flow of blood through the heart? A) 4 3 and 2 1 B) 2 1 and 3 4 C) 1 2 and 3 4 D) 1 2 and 4 3

3 Base your answers to questions 12 and 13 on the diagrams below which represent three common types of blood vessels and on your knowledge of biology. 16. Which statement correctly describes the activities of the components of human blood shown in the diagram below? 12. Which vessel contains valves and transports blood back to the heart? A) 1 B) 2 C) Through the walls of which vessel does gas exchange occur? A) 1 B) 2 C) Oxygen transport in humans involves the bonding of oxygen with A) white blood cells B) platelets C) hormones D) hemoglobin molecules A) Both A and B function in immune responses, and C transports oxygen. B) A, B, and C are able to synthesize hemoglobin. C) Both B and C provide immunity, and A transports nutrients. D) A transports oxygen, B initiates clots, and C functions in immune responses. 17. Bleeding from a small cut soon stops due to the release of enzymes from A) platelets B) activated antibodies C) hemoglobin D) white blood cells 18. The diagram below represents several human blood cells as observed through a compound microscope. 15. Which part of the blood is correctly paired with its function? A) red blood cells fight infection B) plasma transports wastes and hormones C) platelets produce antibodies D) white blood cells carry oxygen Which function is associated with cell X? A) antibody production B) oxygen transport C) phagocytosis D) peristalsis

4 19. What is a major difference between red blood cells and white blood cells? A) Red blood cells contain hemoglobin, but white blood cells do not. B) Red blood cells can move, but white blood cells cannot. C) Red blood cells contain nuclei, but white blood cells do not. D) Red blood cells engulf foreign bacteria, but white blood cells do not. Circulatory Review 20. The immediate source of the intercellular fluid surrounding all human body cells is A) blood plasma B) enzymatic secretions C) lymphatic tissue D) glomerular filtrations 21. The diagram below represents the human lymphatic system. A major function of the structures labeled X is to A) pump lymph in the proper direction B) transport glucose throughout the body C) filter bacteria and dead cells from the lymph D) remove undigested food from the blood

5 22. Five students design an experiment to answer the question: "How is heart rate affected by running?" Two chairs were set up at different ends of a large room. The pulse rate of each student was taken at rest just before running. Each of the five students ran between the chairs a different number of times. Their pulse rates were taken after running and the results are shown in the table below. Explain how the change in heart rate helps to maintain homeostasis during exercise.

The circulatory system transports blood to deliver important substances, such as oxygen, to cells and to remove wastes, such as carbon dioxide.
