What is the ruling on eating the lungs of slaughtered animals, and what are the two types of blood permissible for a Muslim?

Allah has permitted good things for His servants and forbidden impure things. Thus, every good animal is permissible to eat its meat. The lung of an animal, after its ritual slaughter, follows the same ruling as its meat. As for the two types of blood that are permissible, they are the liver and the spleen.
