There is a constant pressure in the arteries, hence the flow of blood in the capillaries is always towards the veins, and, when it gets into the veins, it is prevented from flowing back by the valves in those vessels.
It has also been suggested that the capillaries of different organs show varying degrees of permeability, a suggestion to which we will return later.
The intestines stand next in producing a concentrated lymph, and their capillaries are therefore assumed to stand second as regards permeability.
The capillaries finally terminate in the spaces between the structures of the tissue, but whether their free ends are closed or are in open communication with the tissue spaces is still undecided.
Hence it is argued that their capillaries show the least permeability.
Moreover, the tissues are at any time liable to be injured, and the injury as well as damaging many cells may cause rupture of capillaries (as in bruising) with escape of red blood-cells into the tissue spaces.
Variations in the quantity of lymph issuing from different organs have been on this theory ascribed to differences in the permeability of the capillaries of the organs.
