The solar photosphere-chromosphere, as observed from ground-based observatories, is a very thick atmosphere where phenomena related to magnetic fields, differential rotation, waves, take place. The transition region between the thick atmosphere and the extended thin corona can be observed in the ultraviolet from space observatories such as SOHO and TRACE. In this paper we present some results which show the structuring of the transition region as a result from phenomena having their source in the lower atmosphere and we point out some connections with the corona. An overview of the main characteristics of the transition region obtained from space observations evidences the progress in our understanding of the onset of the solar wind and allows to put constraints on the coronal heating.
