tissue fluid

Cards (6)

what is tissue fluid?
liquid containing water, glucose, amino acids , fatty acids ions and oxygen which surround the tissues
how is tissue fluid formed?
capillaries have small gaps that liquid and small molecules can be forced out
as blood enter the capillaries from arterioles there is high hydrostatic pressure causing ultrafiltration
what stays in the capillaries and dont leave into tissue fluids
red blood cells
platellets
large proteins
how is tissue fluid reabsorbed?
the large molecules remaining in the capillary lower water potential
towards the venous end of the capillaries, hydrostatic pressure is lowered due to its loss of liquid , water reenters by osmosis
why does not all the tissue fluid liquid not get reabsorbed by osmosis? 
because equilibrium will be reached
what happens to the rest of the tissue fluid?
gets absorbed into the lymphatic system and everything drains back into the blood stream near the heart
