Question 1

Based on the body diagram, identify the structure labeled I.


 A. Thoracic duct
 B. Cisterna chyli
 C. Lumbar trunk

,ESTUDYR


 D. Inguinal lymph node

Rationale: The cisterna chyli is a dilated lymphatic reservoir that collects lymph from the lower
limbs and digestive organs.



Question 2

Where does lymph re-enter the cardiovascular system?

 A. Aorta
 B. Jugular veins
 C. Subclavian veins
 D. Hepatic portal vein

Rationale: Filtered lymph drains into the venous circulation at the junction of the internal
jugular and subclavian veins.



Question 3

Which letter identifies the spleen on the body diagram?
[Insert Image 1 here]

 A. A
 B. E
 C. J
 D. G

Rationale: The spleen is located in the upper left abdominal quadrant and filters blood rather
than lymph.



Question 4

Which lymphatic structure drains the right upper limb?

 A. Thoracic duct
 B. Right lymphatic duct
 C. Cisterna chyli
 D. Lumbar trunk

Rationale: The right lymphatic duct drains lymph from the right arm, right thorax, and right side
of the head and neck.

Question 5

Which lymph nodes filter lymph from the lower limbs?

 A. Axillary nodes
 B. Inguinal nodes
 C. Cervical nodes
 D. Thoracic nodes

Rationale: Inguinal lymph nodes receive lymph from the legs, external genitalia, and lower
abdominal wall.
