Deck 27: Lymphatic System and Pathologies

Question 1

Where do B cells mature?

A) Brainstem
B) Thymus
C) Thyroid
D) Bone marrow

Answer 1

D
Explanation: Some lymphocytes mature in bone marrow; they are called B lymphocytes or B cells (B = bone marrow). Once mature, they enter the bloodstream where they facilitate defense mechanisms against intruders.

Question 2

Where is lymph filtered?

A) Thymus
B) Lymph node
C) Lymphatic duct

Answer 2

B
Explanation: Lymph nodes filter lymph before returning it to the blood. In fact, lymph nodes are the only structures that filter lymph.

Question 3

Which structure is bean-shaped and located along the lymphatic chain?

A) Thymus
B) Spleen
C) Lymph node
