Default pale infarcts, hemorrhagic infarcts - loose consistency or dual blood supply

Do you have pale infarcts due to loose consistency or dual blood supply? Thanks

PS This is how I see red (hemorrhagic) infarcts versus pale infarcts, please dis confuse me, if I am wrong.

Hemorrhagic (red) infarcts.
place: Liver, Lung Intestine.
tissue: good consistency
vasculature: DUAL blood supply or RE PERFUSED (confused about concept)?

Pale Infarcts:

place: Heart , Kidney , Liver , Spleen.
Consistency :loose
vasulature: single? (because compartmentalized) ??? --

so questions are

1. Is it hemorrhagic because of the solid consistency or the dual blood supply.

2. I don't get what they mean by re perfused in the lung or liver ?

3. Why is the live in the red infarct and pale infarct category ?


Thanks this topic is so annoying !

hemorrhagic infarcts are dependent both on dual blood supply (lung) and loose consistency (intestine) + other (example-testicular torsion in which venous outflow is blocked with persistence of arterial flow that causes build up of pressure and extravasation of blood in tissue)

pale infarcts occur in tissues with harder consistency (heart, kidney) and single blood supply (spleen)

not sure what about liver in theory it must give red infarct due to dual blood supply, but reality is its very difficult to infarct it
