what part of the internal female anatomy is self-cleaning
Vagina The vagina is self-cleansing and therefore usually does not need special hygiene.[78] Clinicians generally discourage the practice of douching for maintaining vulvovaginal health.[78] Since a healthy vagina is colonized by a mutually symbiotic flora of microorganisms that protect its host from disease-causing microbes, any attempt to upset this balance may cause many undesirable outcomes, including abnormal discharge and yeast infection.[78]
Vein Veins are less muscular than arteries and are often closer to the skin. There are valves in most veins to prevent backflow.
Pulse Pressure waves generated by the heart in systole move the arterial walls. Forward movement of blood occurs when the boundaries are pliable and compliant. These properties form enough to create a palpable pressure wave.
Shekhinah This term does not occur in the Bible, and is from rabbinic literature.[2]:148[3][4]
