structure of lymphatic system: _, _, _ and _.
lymph, lymph vessel, lymph nodes, lymphatic organs.
interstitial fluid fills _ between cells.

also formed by small amounts of protein and other molecules that _ from capillaries.
leak.
lymph is the fluid found in _ vessels.
lymphatic.
lymph is formed by interstitial fluid mixing with protein after entering the lymphatic _.
capillaries.
composed of _, _, _, and other substances.
water, protein, fat.
both fluids resemble _ in composition.
blood plasma.
lymphatic capillaries are _ over the entire body.
networks.
lymphatic vessels are _ capillaries.
blind ended.
pores between endothelial cells open as volume of interstitial fluid _.
increases.
_ are lymphatic capillaries that absorb digested food from the intestines.
lacteals.
larger lymphatic vessels are formed by the merger of lymphatic capillaries and small _.
lymphatics.
the right lymphatic duct drains lymph from the right upper quadrant of the body into the _ vein.
right subclavian.
the _ originates from the _ in the lumbar region.
thoracic duct; asterna chyle.
drains lymph from the _ of body and entire _ side of the body into the _ subclavian vein.
right lower quadrant; left; left.
lymphatic vessels resemble veins except: lymphatics have _ walls, contain more _, contain _.
thinner; valves; lymph nodes.
numerous _ vales present..
semilunar.
lymphatic vessels return _ to blood, return proteins and large _ to blood, and fat and other nutrients from small intestine absorbed by _.
fluid; particles; lacteals.
the valves in lymphatics are _ valves.
one way.
_ through lymphatic vessels is caused by _ movements, skeletal muscle _, arterial _, _ changes, and _ of soft tissues.
movement; breathing; contractions; pulsations; postural; massage.
each lymphnode is surrounded by a _, which extends inward, dividing node in to several cortical nodules.
fibrous capsule.
each cortical nodule is filled with _ cells.
B.
around each _ are sinuses with the lymph.
cortical nodule.
in the center of the node is the _, composed of medullary cords and sinuses.
medulla.
_ are filled with phagocytic cells.
medullary sinuses.
lymph enters the cortical sinuses from several _ lymph vessels.
afferent.
lymph flows into medullary sinuses and then out one of two _ lymph vessels.
efferent.
located in _ lymph nodes.
preauricular.
located in _ and submaxillary lymph nodes.
submental.
located in superficial _ lymph nodes.
cervical.
located in superficial cubital or _ lymph nodes.
supratrochlear.
located in _ lymph nodes.
axillary.
located in _ lymph nodes.
inguinal.
one function of lymph nodes is _.
defense.
defense by _ and _.
filtration and phagocytosis.
_ means there is the maturation of some lymphocytes and monocytes that migrated from red marrow.
hemotopoieses.
lymphatic _ of the breast.
drainage.
two sets of _ drain the breasts.
lymphatics.
lymphatics that originate in and drain _ over the breast.
skin.
lymphatics that originate in and drain breast _.
substance.
85 percent of lymph from breast enters lymph nodes of _ region.
axillary.
_ tonsils are located on each side of the throat.
palatine.
_ tonsils are located at the back of the mouth and are called _ when they become swollen.
pharyngeal; adenoids.
_ tonsils are near the base of the tongue.
linguinal.
the _ consist of two lobes with each lobe divided into two lobules.
thymus.
each lobe has a _ and medulla.
cortex.
_ lymphocytes formed in red marrow move to thymus.
immature.
lymphocytes _ and are distributed to the spleen, lymphnodes, and lymphoid tissue before birth.
mature.
after birth, thymus secretes _, which enables lymphocytes to develop into T cells.
thymosin.
the spleen is located in the left _, directly beneath the diaphram and above the left kidney.
hypochondrium.
enters the white pulp, then the red pulp, then into _.
veins.
the _ is full of lymphocytes.
white pulp.
the _ is reticular tissue submerged in blood.
red pulp.
bacteria are eaten by the spleens _.
mononuclear phagocyte system.
the mononuclear phagocyte system consists of monocytes and macrophages in _ connective tissue.
reticular.
hematopoiesis is the _ of monocytes and lymphocytes,
maturing,
_ formed before birth.
RBCs.
red blood cell and platelet _.
destruction.
the spleen has a normal volume of _ ml of blood.
350.
this volume is decreased by about _ ml by sympathetic stimulation.
200.
msot organs containing developing lymphoctyes quit growing at _.
puberty,
organs being to _.
atrophy.
_ remains intact and does not atrophy.
spleen.
in late adulthood the lymphatic system contributes to the _ of the immune system.
deficiancy.
greater risk of _ and infections.
cancer.
_ conditions more likley.
autoimmune.
