Coach Dav Whatmore admitted his side could not have had a worse opening to a Test series in England.
After several rash shots from their top order, the tourists lost their last five wickets for 19 runs in the space of 33 balls to be bowled out for 108.
"The conditions were totally different to what we've experienced in Bangladesh and we were behind early when we lost the toss," said Whatmore.
"The England bowlers were off the radar but they really moved the ball."
However, Whatmore insisted he was "not going to get the big stick out" after some rare positive signs.
"We saw a good opening partnership until Nafis Iqbal got out and that opened the floodgates," he said.
"If you keep playing at this level you will get better.
"It's like a cricketer from the Western countries coming to the subcontinent. They struggle but the more they play in it the better they get."
England's Andrew Strauss, delighted to have made his first half-century of the summer, felt there was plenty of mitigation for Bangladesh.
"A lot of teams have come unstuck previously when it has swung at Lord's," he said
"Bangladesh struggled with it, but they are far from the first team to do so.
"For us to write them off after the first day of the series would be wrong and premature."
Meanwhile, Whatmore was philosophical about the pull shot that saw captain Habibul Bashar dismissed third ball.
"While he's there the run-rate ticks along quite nicely, he plays his natural shots but I'm sure he wouldn't mind having a replay of that."
And he reserved special praise for debutant Mushfiqur Rahim, who despite making just 19 impressed many observers.
"I think we've all seen enough at this level to know that he's got a pretty bright future," Whatmore added.
"I think he looked a class above the others. He played and missed at a couple and got out to a magnificent delivery and faced some good bowling."
