lymph nodes

afferent vessels

how lymph enters the lymph node

sinus

where the lymph flows after entering

-monocytes and lymphocytes

lymphatic cord

moves around lymph cord

-mono and lymphocyte cells

efferent vessels

where lymph moves out of

lymph path in node

afferent vessel → sinus in cortex → sinus medulla → efferent vessel

lymphocytes mature and become which cells (eliminating pathogens)

NK cells

lymphocytes

t-cells

b cells

nk cells

lymphopoiesis

formation of lymphocytes

anitbodies

monocytes/macrophages

thymus maturation

caused by thymus hormones

lymphocyte→ t cells cells → back to bone marrow→ lymph node

red bone marrow maturation

lymphocyte→ b or nk cells → lymph node

why is lmyph node cleaned

its cleaned because its exposed to monocytes and lymphocytes in the cord and sinus

lymph structure path

afferent lymphatic vessel → germinal center→ medullary cords→ hilus → efferent lymphatic vessel

hilum

the region of an organ where blood vessels, lymphatics, and nerves enter or exit.

germinal center

the parts of lymph nodes in which B lymphocytes proliferate, differentiate, mutate through somatic hypermutation and class switch during antibody responses
