SECTION 1: Lymphatic System Structure & Function (Questions 1-15)
1. Which of the following is a primary function of the lymphatic system?
,A) Transport of oxygen
B) Return of interstitial fluid to the blood
C) Production of red blood cells
D) Synthesis of vitamin D
The lymphatic system returns leaked fluids and proteins to the bloodstream to maintain
fluid balance. It also plays a crucial role in immunity .
2. What is the fluid called once it leaks out of blood capillaries and is picked up by
lymphatic vessels?
A) Blood plasma
B) Interstitial fluid
C) Lymph
D) Chyle
Fluid that originates from blood plasma and leaks out of blood capillaries becomes
interstitial fluid; once picked up by lymphatic vessels, it is called lymph .
3. Where are lymph nodes most densely clustered?
A) Thoracic and abdominal cavities
B) Cervical, axillary, and inguinal areas
C) Pelvic and cranial regions
D) Cardiac and pulmonary regions
Lymph nodes are most dense in the cervical (neck), axillary (armpit), and inguinal (groin)
areas where they filter lymph and contain lymphocytes .
4. Which lymphatic duct drains the upper right quarter of the body?
A) Thoracic duct (left lymphatic duct)
B) Right lymphatic duct
C) Cisterna chyli
D) Subclavian duct
The right lymphatic duct drains lymph from the upper right region (right arm, right side of
head/thorax) into the right subclavian vein .
, 5. Which structure is the largest lymphatic vessel?
A) Right lymphatic duct
B) Thoracic duct
C) Cisterna chyli
D) Subclavian vein
The thoracic duct (left lymphatic duct) is the largest lymphatic vessel, draining
approximately three-quarters of the body into the left subclavian vein .
6. What is the correct order of lymph flow from blood capillaries to venous return?
A) Blood capillaries → interstitial fluid → lymph capillaries → lymph nodes →
lymphatic vessels → lymphatic trunks → thoracic duct/right lymphatic duct →
subclavian veins
B) Blood capillaries → lymph nodes → lymph capillaries → lymphatic vessels → thoracic
duct
C) Lymph capillaries → blood capillaries → lymphatic vessels → lymph nodes
D) Lymphatic vessels → lymph nodes → blood capillaries → subclavian veins
The sequence of lymph flow is: blood capillaries (where fluid leaks out) → interstitial fluid
→ lymph capillaries (where fluid is picked up) → lymph nodes (where lymph is filtered) →
lymphatic vessels → lymphatic trunks → thoracic duct/right lymphatic duct → subclavian
veins .
7. Where are there NO lymph vessels?
A) In the skin
B) Bone marrow and epidermis
C) In the digestive tract
D) In the lymph nodes
There are no lymph vessels in bone marrow and the epidermis (outer layer of skin) .
8. List the sequence of lymph flow from the lymphatic capillaries to the venous
system.
