In this example, a "blow" is a hit. The rest should be obvious. :)

take fall ?

To take a blow, http://theheroine.deviantart.com/art/Zelda-taking-the-blow-27709127 look at the picture.. the heroine is standing inbetween the 'baddy' and the hero and she gets killed instead of the hero. She takes the blow..

It means to accept and withstand a shock Example: Нe took the blow bravely when he learned the truth about the woman whom he had loved

someone else takes the blame for the wrong you have done
