so today I found out(I think this is true) that capillaries cage organs. my questions is

a vertical organ (eg liver) which has capillaries surrounding it(I think). when tissue fluid is released from the capillaries into the cells of the organ. what stops the tissue fluid from collapsing to the bottom of the body due to gravity.


the tissue fluid would surround cells but why doesn't gravity just cause the blood surrounding the cell to just fall to the bottom of the body

It is because there is a high level of hydrostatic pressure, created by the powerful pumping of the heart, which keeps the blood flowing. The blood being pumped behind it causes the blood to move forward.

Hope this helps

Yes, you must remember that solutes are being pushed through the capillary walls and in order to do this, although they're thin, as mentioned above, a high level of hydrostatic pressure is required, which counters any force of gravity x

thanks for your reply. but once pumped to surrounding cells. doesn't it create like a pool surround the cells? if so why doesn't this collapse. or is this due to the lymph vessels acting like a vacuum taking the tissue fluid before it drops
