What does excretory refer to?

The term "excretory" specifically refers to the processes and functions associated with excretion, which is the elimination of waste products from the body. This includes the systems and organs involved in filtering and expelling waste substances, such as the kidneys, bladder, and intestines. Understanding this term is crucial for various medical fields, as it relates directly to how the body maintains homeostasis by removing harmful toxins and maintaining fluid balance. This is distinct from functions related to nutrient absorption, growth and development, or sensory perception, which focus on different physiological processes and systems.
