Term
Lymphatic system
Definition

Functions: transportation of tissue fluid (lymph) to the cardiovascular system, and immunity

consists of lymphatic vessel system, lymphatic tissue, lymph nodes, spleen, tonsils, and thymus

Term
lymphatic capillaries
Definition
pick up lymph and carry it through successively larger vessels and into collecting vessels
Term

right lymphatic duct

 

Definition

present in some but not all individuals

drains lymph from the right upper extremity, head, and thorax, delivered by the jugular, subclavian, and bronchomediastinal trunks

empties lymph into venous circulation at the junction of the internal jugular vein and the subclavian vein

Term
thoracic duct
Definition

receives lymph from the rest of the body

empties lymph into venous circulation at the junction of the internal jugular vein and the subclavian vein 

Term
lymph nodes
Definition

bean shaped

filters lymph

cluster along lymphatic vessels of the body 

contain macrophages

Term
cisterna chyli
Definition
enlarged terminus of the thoracic duct that receives lymph from the lumbar and intestinal trunks
empties into thoracic duct
Term

lumbar trunk

(lymphatics)

 

Definition

receives lymph from lower limbs, pelvis, kidneys, and suprarenal glands

empty into cisterna chyli

Term
characteristics of immune system
Definition

memory

specificity

ability to differentiate self from non-self

Term
spleen
Definition

a dark red organ curving around the left lateral side of the stomach

part of the lymphatic system

often called red blood cell graveyard

located in left upper quadrant of abdomen

Term
thymus
Definition
an irregular mass of glandular tissue overlying the heart
Term

Definition
Term
capsule
Definition

encloses nodes (fibrous)

 

Term
cortex
Definition
outer region of the node
Term
medulla
Definition

internal portion of the gland

cells are arranged in cordlike fashion

Term
hilum
Definition
where efferent vessels of the gland leave the node
Term
lymph node circulation
Definition
lymph enters the node through a number of afferent vessels, circulates through lymph sinuses within the node, and leaves the node through efferent vessels at the hilum
Term
afferent lymph vessels
Definition

bring lymph into the node

enter at all parts of periphery of the lymph node, open into lymph sinuses

found only in lymph nodes!

Term
efferent lymph vessels
Definition

bring lymph out of the lymph node, exit at the hilum

commences from the lymph sinuses of the medullary portion of the lymph nodes and leave the lymph nodes either to veins or greater nodes

also found in thymus and spleen!
