1605 Lymphatic Anatomy Study Resources

AfferentReferring to vessels or nerves that carry fluid or signals towards a particular organ or structure, such as lymphatic vessels bringing lymph into a lymph node.
ArteriesBlood vessels that carry oxygenated blood away from the heart to the rest of the body.
Axillary Lymph NodesLymph nodes located in the armpits, responsible for draining lymph from the upper limbs, breast, and upper wall of the abdomen.
CapsuleThe tough outer covering of a lymph node.
CortexThe outer part of the lymph node, containing densely packed immune cells.
EfferentReferring to vessels or nerves that carry fluid or signals away from an organ or structure, such as lymphatic vessels taking filtered lymph away from a lymph node.
Endothelial CellsCells that form the inner lining of lymphatic capillaries, blood vessels, and the heart, allowing fluid from the surrounding tissue to enter the lymphatic system while preventing the lymph from leaking out.
Germinal CenterAreas within the lymphatic nodules of the cortex of a lymph node where B-cells proliferate and differentiate into antibody-producing cells.
Hip BonesThe bones forming the pelvis, including the iliac crests, which are the upper borders of the pelvis.
Iliac CrestsThe upper borders of the pelvis, part of the hip bones.
Intercostal SpacesThe spaces between the ribs, which are supplied blood by the intercostal arteries.
Intestinal Lymph NodesLymph nodes associated with the gastrointestinal tract, involved in filtering lymph from this region.
LymphA clear fluid that circulates in the lymphatic system, containing white blood cells, especially lymphocytes, which fight infection.
Lymph CapillariesSmall lymphatic vessels that collect excess tissue fluid, now called lymph, from the interstitial spaces.
Lymph NodesSmall, bean-shaped structures that act as filters for harmful substances, containing immune cells that help fight infection by attacking and destroying germs carried in through the lymph fluid.
Lymphatic SystemA part of the circulatory system, comprising a network of lymphatic vessels that transport lymph—a fluid containing white blood cells—to fight infection.
Lymphatic VesselsVessels that form a complex network designed to transport lymph throughout the body.
Lumbar SpineThe part of the spine located in the lower back, consisting of vertebrae and intervertebral discs.
MedullaThe innermost part of a lymph node, containing medullary cords and sinuses through which lymph flows.
PelvisThe lower part of the torso, formed by the hip bones, sacrum, and coccyx.
Rib CageThe part of the skeleton that encloses the thoracic cavity, consisting of the ribs and sternum.
SacrumA large, triangular bone at the base of the spine, forming the upper part of the pelvis.
SpleenAn organ under the ribs on the left side of the body, filtering blood, recycling old red blood cells, and helping mount an immune response.
SternumA flat bone that forms the front part of the rib cage, providing attachment for the ribs.
ThymusAn organ situated in the chest, involved in the maturation of T-cells, which are critical for adaptive immunity.
TrabeculaeSupportive structures within a lymph node that divide it into compartments.
VeinsBlood vessels that return deoxygenated blood back to the heart from the rest of the body.
