The airline are responsible. I have to connect a lot for business travel since my nearest airport isn't a hub, and 45 minute connections are normally fine especially at well run airports like Munich or Zurich.
If the flight is running late, while in the air the cabin crew have a list with everyone on connections and will let you know if you stand a chance of making it - often moving you to the front of the plane and getting you off first.
If you miss it, then they will book you on a later flight.
Obviously if its something like EasyJet this would unlikely count as the connection is not part of the ticket price (you would book separate flights and take the risk).
If it wasn't realistically possible to connect in time, the connection wouldn't be available as part of the deal from the airline.
