[Anatomy and physiology of continence and defecation].
Continence and defecation are two essential functions in humans. Any alteration resulting in anal incontinence and/or constipation can severely impair the patient's quality of life. This study analyzes the anatomical structures and physiologic mechanisms accepted as factors involved in the correct development of both functions, while recognizing that there are still many unclear issues within this complex and sometimes paradoxical structure/function of the human body.
