Question | Answer |
lymphatic vessels collect lymph from what kind of tissue | loose connective tissue |
lymph fluid flows only toward or away from the heart? | toward |
smallest of the lymph vessels which first receive lymph | lymph capillaries |
vessels that collect from lymph capillaries | lymphatic collecting vessels |
areas scattered around the collecting vessels | lymph nodes |
collect lymph from collecting vessels | lymph trunks |
empty into the veins of the neck | lymph ducts |
two functions of the lymphatic vessels | 1) collect excess tissue fluid and blood proteins, 2) return tissue fluid and blood proteins to the bloodstream |
these structures are located near blood capillaries with minivalve flaps that open and allow fluid to enter | lymph capillaries |
does the heart pump on the lymphatic system? | no |
specialized lymphatic capillaries or the small intestine that receive a fatty lymph called chyle | lacteals |
these vessels are composed of the same three tunica as blood vessels | lymphatic collecting vessels |
at the level of the lymph collecting vessels, the movement of lymph is propelled by (3) | 1) bulging of skeletal muscles, 2) pulsing of nearby arteries, 3) tunica media of the lymph vessels |
these structures cleanse the lymph of pathogens (cancer cells, harmful foreign substances, etc) before they reach venous circulation | lymph nodes |
approximately how many lymph nodes are in the human body? | 500 |
these structures are where lymphatic vessels converge | lymphatic trunks |
name the five lymph trunks | lumbar, intestinal, bronchomediastinal, subclavian, jugular |
this lymph trunk receives lymph from the lower limbs and some of the pelvic area | lumbar |
the unpaired lumbar trunk | intestinal |
lymph trunk that receives chyle from digestive system | intestinal |
lymph trunk that collects lymph from thoracic viscera | bronchomediastinal |
lymph trunk that receives lymph from the upper limbs and thoracic wall | subclavian |
lymph trunk that drains lymph from the head and neck | jugular |
lymph duct located at the union of lumbar and intestinal trunks (two names) | cisterna chyli, left lymphatic duct |
the expanded most inferior portion of the thoracic duct | left lymphatic duct |
lymphatic duct that ascend along the vertebral bodies, junction of the left internal jugular and left subclavian veins | thoracic duct |
this lymph duct drains 3/4 of the body | thoracic duct |
the only portion of the body that the thoracic duct does not drain | the right upper quadrant |
lymph duct which empties into the right internal jugular and subclavian veins | right lymphatic duct |
not everyone has this duct | right lymphatic duct |
MALT stands for | mucosa associated lymphoid tissue |
two most important tissues of the immune system | 1) mucous membranes, 2) lymphoid organs |
function of these organs is to gather and destroy infectious microorganisms | lymphoid organs |
where immature T cells mature, secretes hormones | thymus gland |
where is the thymus gland located | near the trachea |
considered lymph organs, place where antigens are destroyed and activate B and T cells | lymph nodes |
located in the ileum of the small intestine, most distal point of the small intestine, densely packed mucosa associate lymphoid tissue, so considered a lymph organ | aggregated lymphoid nodules |
another name for aggregated lymphoid nodules | Peyer's patches |
the largest lymphoid organ | spleen |
two postnatal functions of the spleen | 1) removal of blood-borne antigens, 2) removal and destruction of old/defective blood cells |
prenatal function of the spleen | site of blood cell formation in the fetus |
the tubular offshoot of the cecum (proximal portion of the large intestine) | appendix |
simplest lymphoid organ | tonsils |
which tonsils are the largest and most often infected in childhood | palatine tonsils |
four classes of tonsils | palatine, lingual, pharyngeal, tubal |
this lymph organ is not comprised of true lymphoid tissue | thymus gland |
