Sample Questions Are Posted Below
MULTIPLE CHOICE
| a. | Afferent vessel |
| b. | Efferent vessel |
| c. | Lymphatic duct |
| d. | Capillary |
| e. | Venule |
ANS: A
| Feedback | |
| A | The afferent vessels are a type of lymphatic vessel in which lymph flows into the lymph node. |
| B | The efferent vessel is a type of lymphatic vessel in which lymph flows out of the lymph node in the area of the node’s hilus. |
| C | The lymphatic duct allows the lymph to converge before emptying into the venous system. |
| D | The capillary serves as blood supply for the tissue surrounding the lymphatic system. |
| E | The venule serves to drain the blood supply for the tissue surrounding the lymphatic system. However, the lymphatics do drain into larger vessels of the venous system of the blood in the chest area. |

| a. | Both statements are true. |

| c. | The first statement is true; the second is false. |
| d. | The first statement is false; the second is true. |
ANS: C
| Feedback | |
| A | The second statement is false. The thymus gland is NOT a component of the lymphatic system even though it works within the immune system. |
| B | The first statement is true. The lymphatics are a part of the immune system, and they help fight disease processes. |
| C | The first statement is true. The lymphatics are a part of the immune system, and they help fight disease processes. The second statement is false because the thymus gland is NOT a component of the lymphatic system even though it works within the immune system. |
| D | The first statement is true. The lymphatics are a part of the immune system, and they help fight disease processes. The second statement is false because the thymus gland is NOT a component of the lymphatic system even though it works within the immune system. |

ANS: A
| Feedback | |
| A | The lymph nodes are positioned along the lymphatic vessels to filter toxic products from the lymph to prevent their entry into the vascular system. |
| B | The lymph nodes do NOT liquefy toxic products. |
| C | The lymph nodes do NOT disassociate themselves from toxic products. |
| D | Lymph nodes do NOT oxygenate toxic products. |

| c. | The first statement is true; the second is false. |
| d. | The first statement is false; the second is true. |
ANS: C
| Feedback | |
| A | The second statement is false. The lymphatics on the right side of the head and neck converge by way of the right jugular trunk to join the lymphatics from the right arm and thorax to form the right lymphatic duct, which drains into the venous system at the junction of the right subclavian and right internal jugular veins. The lymphatic vessels of the left side of the head and neck converge into the left jugular trunk, actually a short vessel, and then into the thoracic duct. |
| B | The first statement is true. The lymphatics of the right side of the head and neck converge by way of the right jugular trunk. |
| C | The first statement is true. The lymphatics of the right side of the head and neck converge by way of the right jugular trunk. The second statement is false. The lymphatics on the right side of the head and neck converge by way of the right jugular trunk to join the lymphatics from the right arm and thorax to form the right lymphatic duct, which drains into the venous system at the junction of the right subclavian and right internal jugular veins.
