ability to edit the color of blood using chemicals
flesh can form structures
semen and ovum which can create a small clump of skin, blood, and flesh
urine, & fecal matter which can be combined with nitrogen to make fertilizer which can help plants grow, and fertilizer wont be a hidden item either, feces and urine require anything to be taken through acid in a flesh-like bodily structure and then removed
flesh-based vessels for blood or for the flesh-like bodily structure mentioned with urine and feces (think of pipes, but they can go both ways, and move based off their surroundings
plasma (immune cells) that can be mixxed with blood during an infection
lymph nodes that when connected to vessels, transmit plasma into blood to stop a virus
alveoli, to help process air and then the oxygen is taken into the blood which makes other flesh-like structures stay alive.
make it so that any flesh structure without blood dies
