What is meant by "blood which is not aquatic" and "the blood itself from an animal which is not aquatic"? And does "its regurgitation" (رجیعه) only mean vomit? And do these phrases include the blood of a living human, and is its impurity agreed upon?

The aforementioned text refers to the Kuwaiti Encyclopedia of Fiqh, clarifying that the carrion of an animal with blood is every animal from which blood flows when an organ is removed, and that what is meant by blood itself is the blood coming out of a land animal. The carrion of sea animals and their blood are excluded from prohibition according to the majority of scholars. Jurists have unanimously agreed on the impurity of flowing blood, carrion, urine, and excrement. The majority of jurists consider wine to be a severely impure substance.
