Anteater is a common name for the four mammal species of the suborder Vermilingua (meaning worm tongue) commonly known for eating ants and termites.nteaters are mostly solitary mammals prepared to defend their 1.0- to 1.5-mi 2 (2.6- to 2.9-km 2) territories. Normally, they do not enter a territory of another anteater of the same sex, but males often enter the territory of associated females.
Endocardium (endo-cardium) is the thin inner layer of the heart wall. This layer lines the inner heart chambers, covers heart valves, and is continuous with the endothelium of large blood vessels. The endocardium of heart atria consists of smooth muscle, as well as elastic fibers.
The endocardium does not trigger these contractions, but it helps to regulate them. The endocardium lines the walls of the atria and ventricles and the valves between them. The cellular make-up of the endocardium is close to that of the endothelium, the tissue layer that lines the inside of blood vessels. On its luminal side, or the side closest to the cavities of the heart, it is composed of simple squamous epithelium, a single layer of scaly cells.
