Answer:
The basement membrane or basal lamina on which the epithelium form, made by extracellular matrix.
Explanation:
The basement membrane is the layer underlies all epithelia that is made up extracellular matrix secreted by the epithelium cells that provide structural support to the structure of epithelia.
It forms the barrier between epithelial tissues therefore once a epithelial cancer penetrate this basement membrane it will spread to all underlying tissues.
Thus, the correct answer is - The basement membrane or basal lamina on which the epithelium form, made by extracellular matrix.
The basement membrane is form of extracellular matrix that underlies all epithelia. It provides structural support to epithelia and forms a mechanical connection between epithelia and underlying connective tissue.
The basement membrane, or basal lamina, is a sheet of proteins and other substances to which epithelial cells adhere and that forms a barrier between tissues.
Epithelial cancers may have the ability to penetrate through the basement membrane and spread to underlying tissues.
The answer should be the respiratory system.
When we breathe, air is taken in our body and they travels to the lungs through the trachea. The lungs is the site where the oxygen from the air we just breathed is exchanged with the carbon dioxide (waste).
In the lungs, there's something call air sac, which diffuses the oxygen to the capillaries. At the same time, carbon dioxide from the capillaries diffuses back to the air sac. Then, we breathe out and the carbon dioxide and the remaining substances in the air that we don't need is breathe out.
That explains why there's more oxygen in the unbreathed air than oxygen from breathed air, and less carbon dioxide in unbreathed air than breathed air.
And after that, the capillaries transfer these oxygenated blood to the pulmonary vein, and then transfer them back to the heart.
