9. Describe the function of plasma. Transports materials (blood cells, hormones, wastes…) 10. Describe the function and shape of red blood cells. Disc shaped, no nucleus, carries oxygen & carbon dioxide
11
11. What do red blood cells contain? Hemoglobin (red protein that allows them to carry oxygen)
12
12. A patient has blood type A+. a. What antigens are found on their right blood cells? A antigens b. What antibodies are found in their plasma? Anti-B antibodies c. What does the + sign mean?

14
14. Which blood type is known as the universal donor? Type O a. What blood types can they give blood to? All blood types b. What blood types can they take blood from? Only blood type O.
15
15. Explain the difference between arteries and veins. Arteries carry blood AWAY from heart. Veins carry blood to the heart. Arteries are larger, more muscular and elastic than veins. Arteries carry blood under higher pressure than veins. Veins have valves to prevent the backflow of blood. Arteries do not have valves.
16
16. Explain what occurs in capillaries and why. The exchange or diffusion of substances into or out of the capillary. Capillaries are extremely small and have a VERY thin lining that allows for diffusion to occur.

18
18. Identify the blood vessel described. a. Carry blood towards the heart. veins b. Thickest blood vessel. arteries c. Where the diffusion of substances occurs. capillaries d. Contain valves. veins
19
18. Identify the blood vessel described. e. Blood vessel used when measuring pulse rate. arteries f. Thinnest blood vessel capillaries g. Blood flows through with a lot of pressure. arteries h. Very elastic. arteries
20
Arteries Capillaries Veins 19. Identify the blood vessels below:
21
left ventricle right ventricle left atrium right atrium 20. Identify the structures below. aorta Upper vena cava Pulmonary artery Pulmonary vein
22
21. When blood passes through the heart from the left atrium (D) to the left ventricle (E), it must first pass through a valve
23
22. In which structures does deoxygenated blood pass through? 23. Where is this blood being sent to? H,I,G,F The lungs
24
24. Explain the function of the circulatory system. Transport materials through the body 25. Describe the four chambers of the heart. right atrium & right ventricle – pump deoxygenated blood from cells to lungs Left atrium & left ventricle – pump oxygenated blood from lungs to cells 26. Explain the importance of valves in the heart. Prevent blood from moving backwards 27. Why is the septum so important? Prevents blood in right and left sides from mixing
25
28. Where is deoxygenated blood pumped to? The lungs 29. Where is oxygenated blood pumped to? To body cells 30. Identify the largest artery in the body. Where does it pump blood to? Oxygenated or deoxygenated? Aorta, to all body cells, oxygenated
26
31.Identify the part of the heart being described. a. Chamber that receives oxygenated blood. Left atrium b. Wall that separates the right and left side of the heart. septum c. Chamber that pumps out deoxygenated blood. Right ventricle
27
31. Identify the part of the heart being described. d. Chamber that receives deoxygenated blood. Right atrium e. Prevents the backflow of blood between atria and ventricles. valves f. Chamber that pulps out oxygenated blood. Left ventricles
28
Lower vena cava upper vena cava Left ventricle Right ventricle Pulmonary vein Pulmonary artery aorta Pulmonary artery 32. Pulmonary artery
29
33. Which is the correct sequence for the path of oxygen through the respiratory system? Nasal cavity Pharynx Larynx Trachea Bronchi Bronchioles Alveoli
30
34. The tubes that branch from the trachea are the 35. The dome shaped muscle below the chest cavity is called the 36. During swallowing, the air passage of the pharynx is covered by the 37. Alveoli in the lungs are connected to the bronchi by a network of tiny tubes called bronchi diaphragm epiglottis bronchioles
31
38. Explain what happens to gases during gas exchange in the alveoli. Oxygen in alveoli diffuses into capillaries (blood). Carbon dioxide in capillaries (blood) diffuses into alveoli.
32
39. Where are the vocal cords located in the body? 40.What prevents the trachea from collapsing? 41. Where does the actual exchange of gases occur? 42. During gas exchange where does the oxygen and carbon dioxide go? larynx rings of cartilage alveoli O2 diffuses into capillaries. CO2 diffuses out of capillaries and into alveoli.
33
43. The ______ is a long straight tube that carries air from the back of the throat to the lungs. trachea

35
45. The order of air movement with in the lungs is best described as a)bronchioles to bronchi to alveoli b)bronchi to bronchioles to alveoli c)trachea to bronchi to alveoli d)bronchi to alveoli to bronchioles
36
46. Where are the vocal cords located in the body? Larynx
37
47. During swallowing, the air passage of the pharynx is covered by the epiglottis
38
48. The FIRST branches off the trachea are called bronchi
39
49. What prevents the trachea from collapsing? rings of cartilage
40
50. Alveoli in the lungs are connected to the bronchi by a network of tiny tubes called a)arterioles b)venules c)capillaries d)bronchioles
41
51. Inside the alveoli, carbon dioxide and oxygen a)are transported along microscopic tubules b)are exchanged between air and blood c)are produced inside cells d)are exchanged for other gases
42
52. Humans breathe more rapidly during exercise than before it because during exercise the blood contains 1.an increased level of oxygen 2.a decreased number of red blood cells 3.an increased level of carbon dioxide 4.a decreased amount of hemoglobin
43
43. What happens to each of the following during inhalation? a. Diaphragm b. Rib cage c. Pressure in chest cavity contacts (pulls down) expands decreases
44
44. What happens to each of the following during exhalation? a. Diaphragm b. Rib cage c. Pressure in chest cavity relaxes (moves up) relaxes increases
