11. This flap is vascularized by the internal mammary perforators. 12. These areas were vascularized , hence the conclusion that they were secondary breathing organs. 13. As such, they also have a tendency to calcify and are highly vascularized . 14. The endometrium is highly vascularized ( it contains an extensive network of capillaries ). 15. Crocodiles have very vascularized osteoderms, that serve as protective features and for thermoregulation. 16. The air sacs are poorly vascularized but show an increased temperature, which aids in heat loss. 17. They tend to be encapsulated and vascularized tumors that do not cross the midline of the abdomen. 18. In hemagioblastoma, HIF1A expression is found in most cells sampled from the well-vascularized tumor. 19. The shell is made of bone covered by living vascularized tissue and covered with a layer of keratin. 20. Inside the mantle cavity the animal has a highly vascularized area of tissue that functions as a lung.
