As adventitia or adventitia (of lat. Advenire - to come), the outer layer is referred to tubular organs in the anatomy. The adventitia consists of loose connective tissue , serves to anchor it in the environment and, unlike a tunica serosa, has no epithelial layer. Supplying blood vessels and nerves also run in the adventitia .
Own an adventitia:
- Blood vessels ( arteries , veins ): also referred to as tunica externa , only very large blood vessels have their own blood vessels for supply ( vasa vasorum )
- Trachea and bronchi
- Bile duct
- Renal pelvis , ureter
- Epididymal duct , parts of the vas deferens and the accessory sex glands
- Vagina and vestibule
