Thermoplastic is known to be a plastic material with a polymer that can be molded above a specific temperature and solidifies upon cooling. Thermoplastics can be remelted or reshaped by heating and they have low melting points. Furthermore, they usually have high concentration of polymers with amorphous structures, the material will have a poor resistance to loads but it will have an excellent elasticity.
Nephrons are the filtering structures of the kidneys. The
kidneys contain millions and millions of these tiny filtering structures that
are responsible for cleaning the blood. Nephrons are responsible for removing
excess water, wastes, and other substances in the blood that are not needed by
the body. They also return necessary substances (e.g. sodium, potassium,
phosphorus) whenever the body runs low in supply.
If these nephrons are damaged, blood will not be properly
filtered. As a result, the kidney will have different diseases and this might
lead to kidney and multiple organ failure.

Answer: The function of the Alveolar type II cells is that they secrete a lipoprotein material that is known as surfactant. The primary function of the surfactant is to reduce the surface tension in the alveoli.
Explanation:
Type II have an important function Type II as they secrete pulmonary surfactant in order to lessen the surface tension of water and allows the membrane to separate, therefore increasing its capability to exchange gases.
