Explanation:
It is called a direct object to the function that assumes a syntactic constituent, different from the grammatical subject, which is mandatorily requested by a transitive verb. Also known as a direct complement, its function is related to the accusative case.
In Spanish, the direct object can always be replaced by "la”, “las”, “lo” or “los”.
