blood and lymph are connective tissue fluid matrix that surrounds cells includes many suspended
proteins that do not form insoluble fibers
in blood, watery matrix is called plasma
plasma — contains formed elements — blood cells and fragments of cells
RBC
WBC
platelets
body has a lot of extracellular fluid, includes
three subdivisions — plasma, interstitial fluid,
lymph
Fluid tissue transport systems
plasma —
confined to
vessels of
cardiovascular
system
arteries — carry blood away
from heart and into tissues
of body
in those tissues, blood pressure forces
water and small solutes out of bloodstream
across walls of capillaries (smallest blood
vessel)
remaining blood flows from
capillaries into veins that
return to heart
lymph — forms as interstitial fluid enters lymphatic vessels monitored by immune system so
lymph transported by lymphatic (lymphoid) system lymphatic vessels return lymph to large veins
near heart (venous system)
