Where did the blood come from (if there was any) in Jesus resurrected body?
Lazarus came out of the crypt in a mortal body. He was not "resurrected" into an immortal body. It was Jesus who was the first-begotten out of the dead (ones). So, however this happened, Lazarus had to suffer a physical death again.
"For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstbornfrom the dead among many brethren" (Rom. 8:29 AV).
"And he is the head of the body, the church: who is the beginning, the firstborn from the dead; . . ." (Col. 1:18 AV).
"And from Jesus Christ, who is the faithful witness, and the first begotten ofek=out of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood, . . ." (Rev. 1:5 AV).
"Firstborn" (πρωτοτοκος proh-to-to-kos) means first in time as well as first in place.
Anything less is from the evil one; and any idea that His resurrected body with blood somehow detracts from the finality of His shed blood on the cross is also from the evil one.
What detracts from the finality His shed blood is the (erroneous) concept that somehow He got more blood that was unshed. There is nothing anyplace in the Bible that ever says that His resurrected body was mortal with blood in it, rather than an immortal body without blood, where life is in the Spirit. Flesh, yes. Bone, yes. Blood, no.
I think we are; once again; arguing the unknowable.
