Lungs

Lungs oxygenate blood moved through them by a heart on the same artery network. Provided there is a fed stomach on the same network, the blood oxygenates and nourishes any flesh and carapace within a certain radius of an artery.

Oxygenated and nourished blood ensures flesh and carapace retain their healing capabilities.

If a lung block is surrounded on all sides by atmosphere, it will expand until it occupies the entire room it is currently in. Larger lungs will be able to provide more oxygen to the ship.

Requires: Electricity, oxygen, heart and fed stomach on the same artery network
