Primary organs of immune system
thymus and red bone marrow, train B and T cells to not attack self
transport tissue fluid to blood, protect body (clean tissue with lymph nodes)
similar to veins, more valves, thinner and pass through lymph nodes
2 ducts of lymphatic system
right lymphatic and thoracic ducts
drains the right upper extremedies, head and thorax
drains the rest of the body that the right lymphatic duct doesn't train (abdomen and legs)
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)
broken up into innate(born with) and adaptive(learned such as B and T cells)
antibodies( more predominantly found in red bone marrow)
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
exchange of gas between blood and air filled chambers of the lungs ( oxygen loading and CO2 unloading)
exchange of gases between systemic blood and tissues cells (O2 unloading, Co2 loading)
