Quiz lymphatic
splenic artery, splenic vein, nerves, efferent lymphatic vessels
structures that enter and exit the hilum of the spleen
afferent lymphatic vessel-subcapsular sinus-trabecular sinus-medullary sinus-efferent lymphatic vessel
lymph flow thru lymph node
red marrow adn thymus
primary lymphatic organs
Thoracic duct and right lymphatic duct (form lymph trunk)
main ducts of lymphatic system
Thoracic duct
longer; on left side of body
drains lymph from left side of body, legs and abdomen
Thoracic duct
right lymphatic duct
shorter; drains lymph from R arms, R side of thorax, head, and neck
dilation in the beginnng of thoracic duct
cisterna chyli
made of reticular tissue
lymph nodes
filters lymph fluid and produce lymphocytes
lymph nodes
filters interstitial fluid from soft tissue adn return it to the vascular; helps lymph drainage
Lymph nodes
Cortex (super region) and Medulla (deeper region)
lymph node structures
Afferent vessels (lymph node structure)
where lymph enters into
Efferent vessels (lymph node structure)
where lymph exits
hilum (lymph node)
indented region where efferent vessels exits the node
contains immune cells
lymphatic nodules foudn in outer cortex
trabeculae (lymph node)
divides the node into compartments
Thymus
stimulate immature T cells as they come from bone marrow into maturation
Spleen (white pulp)
contains macrophages and lymphocytes
where B and T cells perform immune functions
Spleen (white pulp)
Spleen ( red pulp)
storage location of platelets
largest lymphatic organs
spleen
primary function is to filter foreign particles and organisms from blood, eliminate older erythrocytes, and acts as a reservoir for platelets
spleen
immune response
lymphatic function
collecting interstitial fluid and returning it to blood stream
lymphatic funtion
delivering lipids adn lipid soluble nutrients from small intestines-Vit DAKE
lymphatic function
Mucosa-associated lymphoid tissue (MALT)
consist of singular lymphatic nodules found within the mucous membranes of the respiratory, digestive, urinary and reproductive tracts
Peyer's patches
collection of nodules in small intestines
tonsils nodules
pharyngeal, palatine, lingual
Brachial nodules
lymphatic tissue in the respiratory tract
lymphatic vessels
thinner walls than blood vessels and has more valves but follow the same pathway as blood vessels
lymph
located in lymphatic vessels and lymph nodes
delivers nutrients and proteins to cells and tissue
lymph
protects against infection
lymph
removes wasrte
lymph
maintains fluid balance
