ELI5: What does the vote to defund planned parenthood mean and how is it related to the govt. shutdown?

I've tried to look around, but most of the news sources I've found are hopelessly vague in their explanation (something I sometimes wonder if intentional)

I understand it was voted to defund planned parenthood for 1 year. What does this mean for planned parenthood to be defunded? And hoow does this vote relate to the threat of a government shutdown that keeps being mentioned?

So, the House of Representatives passed a bill that would remove government funding to Planned Parenthood. That bill would then need to go to the senior half of Congress, the Senate, and pass there. Then it would go to President Obama, who has the power to veto it and will almost certainly do so. 

Several Republican congressmen have said that they will refuse to vote on any US budgets that give money to Planned Parenthood at all, and since the Democrats are not going to just give up on funding Planned Parenthood, this means that it is likely that no budget will be passed for the upcoming year, and thus no federal funds will go anywhere and the US government will shut down until negotiations result in Congress approving a budget.
