Tree trunk cross section

Cross-section of a tree trunk or woody stem showing heartwood as the dark dense central core, circular to oval in shape and colored dark brown to reddish brown. The heartwood occupies the innermost older secondary xylem region and appears dry, solid, and denser than the surrounding lighter sapwood. Visible concentric annual growth rings run through the wood, and in fuller trunk views the lighter outer sapwood surrounds the heartwood with bark at the outer edge.
