Idiomatic Usage & Expressions
While “physiology” is primarily technical, it appears metaphorically in contexts like:
- “Work out the physiology of…” – understand how something functions

Sample Sentences
- Understanding kidney physiology helps doctors treat renal disease.
- She wrote her thesis on insect physiology and environmental adaptation.

Does “Physiology” Have Any Relationship to Sexuality?
Yes, indirectly.
- Reproductive physiology is a major subfield that studies sexual organs, hormonal cycles, and the processes of conception and childbirth.
- Sexual function (e.g., arousal, fertility) falls under physiological study, but “physiology” itself is neutral and refers broadly to all body functions.
- In everyday use, physiology does not imply sexuality unless context specifies reproductive or sexual systems.
