Surrounding the vascular bundles is a layer that varies in thickness in different species and is called the cortex. In some parts of the body, such as the gut and bone marrow, stem cells regularly divide to produce new body tissues for maintenance and repair. From the outside to inside, the layers of stems are: bark or epidermis, phloem, cambium, xylem and, finally, pith.
