Primary organs of immune system

thymus and red bone marrow, train B and T cells to not attack self

Lymphatic function

transport tissue fluid to blood, protect body (clean tissue with lymph nodes)

Lymphatic vessels

similar to veins, more valves, thinner and pass through lymph nodes

2 ducts of lymphatic system

right lymphatic and thoracic ducts

Right lymphatic

drains the right upper extremedies, head and thorax

Thoracic duct

drains the rest of the body that the right lymphatic duct doesn't train (abdomen and legs)

lymphatic capillaries

start in capillary beds( blunt ended) anchored to connective tissues) compared to blood capillaries, these are one way valves, wider, and anchored


encapsulated capsule, 5 afferent path ways into/ 2 efferent pathways out


structure that protrudes from the outside wall of a lymph node to the inside


macrophages here, germinal center( B cells hang out here)

Immune system

broken up into innate(born with) and adaptive(learned such as B and T cells)

B cells

antibodies( more predominantly found in red bone marrow)

T cells

kill cells and help B cells(more predominantly found it thymus)


very thin walls, wrapped by capillaries to increase surface area ( promotes more gas exchange)

nasal cavity mucosa

warm, moisten, and filter the incoming air

external respiration

exchange of gas between blood and air filled chambers of the lungs ( oxygen loading and CO2 unloading)

internal respiration

exchange of gases between systemic blood and tissues cells (O2 unloading, Co2 loading)
