Wales, Scotland, and England have their own teams (Northern Ireland contributes to the Irish team). The common explanation I've seen is that the nations have deep, distinct histories and cultures, but that doesn't explain why, for example, India doesn't get to send a team from each state despite India's ethnic groups being even more diverse and distinct than those of the UK.
So what is the actual reason for Britain into three parts for the purpose of international sport but not other countries?

Lots of countries have multiple nations that participate in international soccer. For instance, the US fields the USMNT, but also American Samoa. It is nations, rather than states, that are represented at the World Cup.

This is it exactly: the UK is made up of separate nations, and each nation is allowed to be separately represented.
Another example is the Faroe Islands, which is part of the kingdom of Denmark but has their own World Cup team.
