Epithelial cells centroacinar (or epithelial cells centriocinar) are cells that are found in the center of the acini in the lungs. They are part of the epithelial tissue that covers the surface of the lungs and plays an important role in filtering air and releasing carbon dioxide.
Centroicinar epithelial cells are spherical in shape and contain many microvilli on their surface. These microvilli help them capture and hold particles that may enter the lungs when breathing. In addition, centriacinar epithelial cells are also involved in the production of mucus, which protects the lungs from infections and other damage.
However, if the epithelial cells begin to become damaged or destroyed, it can lead to various lung diseases such as chronic bronchitis, asthma and lung cancer. Therefore, it is important to maintain the health of centriacinar epithelial cells and monitor your health.
Central acinar epithelial cells are cells located in the germinal centers of the alveoli and having a large acinar shape, which suggests their presence in the centers of the lobular structure and fascicular structure of the blood organ.
Epithelial cells usually play an important role in the formation of trabeculae (banding) of tissue. Although it often contains large variations in size and shape, as well as different types of cytoplasm that are determined by the particular tissue type or element, its precise characteristics are determined by the local histology and type of tissue data. It is the most characteristic representative of ordinary cells and is characterized by a compact shape with many long processes in the cytoplasm or microvilli, or their association (see V). These special structures can be seen both at the margin and under the electron microscope (to study ultrastructure) and are associated with the production and secretion of substances or the absorption of additional substances from the surrounding tissue (via foot and tight junctions).
Differences in the structure and size of structures and other types of epithelial cells are especially noticeable when considering dense connective tissues (labroin), skin, respiratory organs, and mucous membranes. Other cell types, such as ependymoglial glial cells, juvenile neuroglia, neuroglial (wound), synaptoblastic, endothelial vascular, and chorionic germ cells, are also often associated with a wide variety of prominent structures.
The observed epithelial structures are expressed in the cell nucleus; ratio of the amount of nucleoplasmomassnuclear material; density and quality of cytoplasmic fibers or granules (microvesicles); quantity and degree of lamyris (clans of tissue layers), lipid and glycosidic micronite; the possibility of significant monolayering, the number and nature of attachment macromolecular surfaces, such as glycosaminoglycol, mucopolysaccharide and carbohydrate complexes or proteoglycons; number and structure of surface receptors and membrane-bound enzymes; the presence of precursor cells and the amount of multilayer synthetic tissue and associated adhesives
