Question 1

4. What is the function of lymph nodes?

Answer 1

To trap disease-causing bacteria (70. WKST - Blood & Lymph)

Question 2

15. Place the following order in sequence: A) The atria filled with blood B) The valve between the ventricles and atria close C) Blood is pushed out of the heart

Answer 2

A, B, C (64. CLF - Pathways of the Blood)

Question 3

27. When the ventricles contract blood is pumped

Answer 3

Out of the heart (64. CLF - Pathways of the Blood)

Question 4

29. What causes blood pressure?

Answer 4

The force with which the ventricles contract (69. WKST - The Body’s Transport System)

Question 5

37. Which of these heart structures prevents blood from flowing backward?

Answer 5

Valve (71. CLF - Interior of the Heart)

Question 6

45. What happens after old blood which has already been circulated through the body moves into the heart?

Answer 6

The old blood travels to the lungs for more oxygen (BP - Blood)

Question 7

48. The ______ ventricle pumps blood to the lungs

Answer 7

Right (64. CLF - Pathways of the Blood)

Question 8

51. Blood flows from the heart to the body through ________

Answer 8

Arteries (64. CLF - Pathways of the Blood)

Question 9

52. The force with which the _________ contract causes blood pressure

Answer 9

Ventricles (69. WKST - The Body’s Transport System)

Question 10

54. Blood that is rich in oxygen leaves the heart through the blood vessel known as the ________

Answer 10

Aorta (66. CLF - Exterior of the Heart)

Question 11

59. Fluid from the blood that enters lymphatic vessels is known as _______

Answer 11

Lymph (70. WKST - Blood & Lymph)

Question 12

60. A flap of tissue called ________ separates the right atrium from the right ventricle and prevents a backward flow blood

Answer 12

Valve (71. CLF - Interior of the Heart)

Question 13

62. The circulatory system carries the needed materials oxygen and _________ to the body cells

Answer 13

Glucose, nutrients (69. WKST - The Body’s Transport System)

Question 14

65. What is the left lower section of the heart called? When blood enters this structure, is the blood low in oxygen of high in oxygen? Explain

Answer 14

Left ventricle - high in oxygen because it’s coming from the lungs (64. CLF - Pathways of the Blood)

Question 15

67. What is the structure in between the left atrium and left ventricle? What is it’s function?

Answer 15

Valve - separates the left atrium from the left ventricle, prevents blood from flowing backward from the ventricle into the atrium (71. CLF - Interior of the Heart)

Question 16

68. What is the structure that separates the right and left side of the heart? What would happen to a person who had a hole in this structure?

Answer 16

Septum - a hole in the septum would allow oxygen-poor blood to mix with oxygen-rich blood, as a result, less oxygen would go to body cells (71. CLF - Interior of the Heart)

Question 17

70. What is the left top section of the heart called? What are the blood vessels called that lead into this structure? What is it’s level of oxygen content?

Answer 17

Left atrium - pulmonary veins - high oxygen (64. CLF - Pathways of the Blood)

Question 18

73. Starting with the Vena Cava, show the pathways of the blood and if the blood is oxygenate or deoxygenated.

Answer 18

Superior vena cava, inferior vena cava, deoxygenated, right atrium, deoxygenated, right ventricle, deoxygenated, pulmonary trunk, deoxygenated, LUNGS, right pulmonary vein, left pulmonary vein, oxygenated, left atrium, oxygenated, left ventricle, oxygenated, aorta, oxygenated, BODY (64. CLF - Pathways of the Blood)

Question 19

74. Where are pulmonary arteries? Where are pulmonary veins?

Answer 19

Pulmonary arteries - under the aortic arch. Pulmonary veins - by the left atrium (64. CLF - Pathways of the Blood)
