Ionized gas in the CALIFA galaxies

We present here the most recent results we have obtained in our exploration of the gas abundances using the IFU data from the CALIFA survey. Using our own developed tools we have extracted the ionized gas properties of ~10.000 HII regions, in order to explore: (i) the relation between these properties and those of the host galaxies and the underlying stellar population; (ii) the local relation between the gas abundance and the stellar mass density; (iii) the abundance gradient, and its universal nature. We illustrate why it is extremely important to acquire spatial resolved information on the cold-gas phase to understand the overall chemical evolution of galaxies.
