Learn Hardcore Russian: Я посетил врача, потому что чувствовал боль.

In Russian, when a verb takes a direct object, the noun in the accusative case may change its ending depending on its animacy. Врач is an animate masculine noun, so its accusative singular form is identical to its genitive singular form—врача. This is why the sentence uses врача instead of the nominative врач.
