English term
dependency

In the following sentence:
The rash of all vasculitis syndromes predominates on the lower extremities and the buttocks, most likely due to leakage of red blood cells secondary to dependency and gravity.
Is it something like inertia? Any descriptive explanation of this property will be welcome.

parts below the heart
Blood is actively pumped to the extremities by the heart but return blood flow is much more passive and depends on factors such as gravity and muscle activity (which indirectly squeezes blood back to the heart). This return blood flow can be slowed by dilatation of the veins, obstructions to flow or reduction of surrounding muscle activity.
Thus blood tends to pool in DEPENDENT areas - that is, areas below the heart. Gravity plays a role, but as mentioned above, it is not the only factor. BTW, I am an expert. ;-)

Comment: "Thank you. We do not have one word describing such relationship s. So in Polish I guess I will put it like "other factors affecting venous return". "

when a tissue or organ is below heart level
Not an expert - but seems to point that way.
Our findings show that dependency (when a tissue or organ is below heart level) affects the function of both the lymphatic vessels and the veins.

Note from asker:
| OK, but what will be the difference between gravity and dependency here? Being below heart level means that blood has to flow against gravity, unless we involve here hydrostatic forces and heart walls compliance |

dependency on dialysis or steroids
Looking up vasculitis on Google comes up with quite a few pages citing dialysis dependency and steroid dependency in some patients depending on how long they've suffered from the disease. Is there any mention of either in the rest of the text?
Note from asker:
| No, its rather dependence that is used in your context, and it just means that you cannot go without these measures, not the case here. Thanks a lot anyway. |

: Yes, the word is "dependence".
