Lymphatic system Flashcards

Major components and organs- structures and roles

1
Q

What are the two primary functions of the lymphatic system?

A

Transport tissue fluid (lymph) to blood vessels. 2. protect the body by removing foreign material (bacteria) from the lymphatic stream and serve as a site for lymphocyte “policing” of body fluids and lymphocyte multiplication

A

B & T cells

18
Q

Which cells originate in red bone marrow?

A

B & T Cells

19
Q

riggered when an antigen binds to the specific cell-surface receptors causing the cell to proliferate rapidly, forming clones which then become specialized (differentiate) some form memory cells, other regulatory cells
