LAB(immune and respiratory system)

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)
