Morphology
The phrase is a polite euphemism where 'nature' metaphorically stands for bodily urges and 'calls' signals an inner need; this metaphorical leap is understandable but not strictly compositional from the literal meanings. Some learners may infer the restroom sense from context or cross-linguistic parallels, but the specific bathroom meaning is not fully predictable without exposure, so it is partially transparent.
Etymology
When nature calls treats the body's need to go to the toilet as if nature itself 'calls' you for attention. So, it is a polite, slightly funny way to say 'to go to the toilet'.
