Terms | Definitions |
|---|---|
 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 |
| hilum | encapsulated capsule, 5 afferent path ways into/ 2 efferent pathways out |
| trabeculae | structure that protrudes from the outside wall of a lymph node to the inside |
| medulla | 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) |
| Alveoli | 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) |
