Morphology
The meaning is directly compositional: 'excretory' (related to eliminating bodily waste) combined with 'organ' (a body part with a function) yields 'an organ that removes waste'. This follows common biomedical naming patterns found across languages, so a B1 learner who knows both constituents would readily infer the MWE meaning.
Etymology
Excretory organ names a body part that sends waste out: excretory, meaning 'to send out', and organ, meaning 'a body part'. The phrase gives the image of a drain or filter that moves unwanted waste from the blood out of the body, so it means 'an organ that removes waste products'.
