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.

Phyllite is a type of foliated metamorphic rock.
Slate is a, fine-grained, clayey metamorphic rock.
Shale is a parent rock to slate and phyllite.

Answer:
oropharynx
Explanation:
The pharynx, which is sometimes referred to as the throat, is the cone-shaped muscular tube that links the oral and nasal cavity to the larynx and oesophagus. The pharynx, which serves as a passage for movement of food from the mouth to the esophagus and also as an airway, is divided into three parts, namely: the nasopharynx, oropharynx, and laryngopharynx.
The oropharynx is the part that receives both air and food. It is the middle part of the pharynx (throat) found at the back of the soft palate of the mouth and also underneath the nasopharynx.
 
        
                    
             
        
        
        
Embryonic stem cells are pluripotent cells that are derived from the inner cell mass of a blastocyst before implantation. These cells have potential of treating a wide range of diseases and conditions, which is attributed to the fact that they have; self renewal property meaning that they can ploriferate indefinitely, the cells also have the special ability to differentiate into cells with specialized characteristics and functions. In addition the cells are unspecialized and therefore they can give rise to specialized cells.
