c) It is made up of arterial capillaries
and venules that regulate the blood flow distribution to each organ
Patients with proximal femoral osteoporosis have been reported with reduced density of arterial capillaries
and more frequent arteriosclerotic vascular lesions .
Other authors support the method of intra--arterial low--dose thrombolysis via the common femoral artery, reasoning that the arterial route delivers the thrombolytic agent to the arterial capillaries
and, subsequently, to the venules.
As a result, the amount of fluid filtered out through the arterial capillaries
is equal to the amount of fluid reabsorbed at the venous ends.
