If you don’t have much existing job experience, volunteer and internship work is a great addition to your CV. Most of the time, you can put this under your work experience section. However, if you have job experience, you should put volunteering and internship work in their section or exclude them altogether. This type of work also goes under the same guidelines as work history—there’s no need to include work from over 10 years ago, as it’s unlikely to impact how you work today.
