5) Lymph is similar to what other bodily fluid?
A) Blood
B) Plasma
C) Urine

6) Which of the following statements about lymph and lymph vessels is false?
A) Lymph leaves the system of blood vessels through the capillaries due to blood pressure.
B) Lymph returns to the cardiovascular system through a network of open lymph capillaries and vessels that drain the tissues of lymph.
C) Valves inside the lymph vessels direct the flow of lymph in either direction.
D) Lymph vessels eventually drain into one of two collecting ducts, the thoracic duct and the right lymphatic duct.

Answer: C
Explanation: Lymph leaves the system of blood vessels through the capillaries due to blood pressure. Lymph must then return to the cardiovascular system through a network of open lymph capillaries and vessels that drain the tissues of lymph. Gaps between the endothelial cells of the lymph capillaries allow lymph, bacteria, and even loose cells to enter the vessel. Valves inside the lymph vessels direct the flow of lymph to larger and larger lymph vessels. Lymph vessels eventually drain into one of two collecting ducts—the thoracic duct and the right lymphatic duct.

7) Which of the following statements about lymph and lymph vessels is true?
A) Lymph leaves the system of blood vessels through the veins due to blood pressure.
B) Lymph returns to the cardiovascular system through a network of open lymph capillaries and vessels that drain the tissues of lymph.
C) Valves inside the lymph vessels direct the flow of lymph in either direction.

8) Where do the thoracic and right lymphatic ducts deliver lymph?
A) Aorta
B) Inferior vena cava
C) Subclavian vein
D) None of these are correct.

Answer: C
Explanation: The thoracic and right lymphatic ducts deliver lymph to the subclavian veins where it rejoins the circulating blood.

9) Which duct drains lymph from the head, the right arm, and the right side of the thorax?
A) Right lymphatic duct
B) Thoracic duct
C) Subclavian vein
D) None of these are correct.

Answer: A
Explanation: The right lymphatic duct drains lymph from the right side of the head, the right arm, and the right side of the thorax to the right subclavian vein. The thoracic duct delivers lymph from the rest of the body to the left subclavian vein.

A) Right lymphatic duct
B) Thoracic duct
C) Subclavian vein
D) None of these are correct.

Answer: B
Explanation: The right lymphatic duct drains lymph from the right side of the head, the right arm, and the right side of the thorax to the right subclavian vein. The thoracic duct delivers lymph from the rest of the body to the left subclavian vein.
