QuestionAnswer
Epithelial: skin cell. Function = support [swells] and protection [from pathogens, disease causing organisms]
Olfactory Cell changes depending on where found eg nose, trachea bith have cilia; alveoli don’t. Function = Makes surfactant, an oil that coats the inside of the alveoli and stops drying out as well as aids gas diffusion.
Ciliated cell The mitochondria are found at the top but the cell nuclei are towards the base and are often elongated. The rowing-like action of epithelial cilia work in time with goblet cells to push mucus away from the lungs etc, preventing the cause of infection
Support cell Olfactory cells are really a form of bipolar neuron as with any other neuron, they're so specialized they need a set of supporting cells
Basal membrane cell prevents air bubbles from forming in the blood, and from blood entering the alveoli.
Alveolar type I cell squamous [able to be flattened] pulmonary epithelial [outside of alveoli] cells. Is lining cells of alveoli and becoming Type II.
Function secretes surfactant (rich in phospholipids) and absorbs sodium and water and gases
Fibroblast structural component of alveoli made of cologne and “fibre”. Function = Holds alveoli open.
Macrophage disease fighter Function =remove cell debris and foreign material (e.g. dust, bacteria) from the lung.
Red blood cell biconcave bag with no nucleus and full of haemoglobin to carry oxygen and carbon dioxide.
Monocyte immune system blood cell that can form other fighting white blood cells.
Endothelium inside skin Function = Barrier between the vessel [tube] lumen [hole] and surrounding tissue, controlling the passage of materials and white blood cells into and out of the bloodstream.
