alveolar cell

Cuboidal type II alveolar cell usually forms part of aperture.

Great alveolar cells also repair the endotheilium of the alveolus when it becomes damaged.

There are three major alveolar cell types in the alveolar wall (pneumocytes):

Surfactant is a surface-active lipoprotein complex formed by type II alveolar cells.

This Protein has been found to have functions in lung alveolar cells, kidney podocytes, and lymphatic endothelial cells.

Other cells that contain hemoglobin include the A9 dopaminergic neurons in the substantia nigra, macrophages, alveolar cells, and mesangial cells in the kidney.

Outside the brain, hemoglobin has non-oxygen-carrying functions as an antioxidant and a regulator of iron metabolism in macrophages, alveolar cells, and mesangial cells in the kidney.

The components for these lipids diffuse from the blood into type II alveolar cells where they are assembled and packaged for secretion into secretory organelles called lamellar bodies.

Type II pneumocytes also called alveolar type II cells, great alveolar cells or septal cells are granular and roughly cuboidal in shape.

The x-ray usually reveals a diffuse alveolar filling with air bronchograms, described as a ground-glass appearance, and similar to pneumonia, pulmonary edema, alveolar hemorrhage, and alveolar cell lung cancer.

Some AO activity has been located in other parts of the body--including the lungs (epithelial cells and alveolar cells), the kidneys, and the gastrointestinal tract (small and large intestines).

Prior to clinical recognition of DPB in recent years, it was often misdiagnosed as bronchiectasia, COPD, IPF, phthisis miliaris, sarcoidosis or alveolar cell carcinoma.

The surfactant is produced by great alveolar cells (granular pneumonocytes, a cuboidal epithelia), which are the most numerous cells in the alveoli, yet do not cover as much surface area as the squamous alveolar cells (a squamous epithelium).
