Stem Cells Types and Advantages

Stem cells are the primary cells capable of reforming themselves through mitotic division and differentiating into specialized cells. These cells serve as repair system of the body and are present in all multicellular organisms.   Types of Stem Cells Stem cells are of two types: Embryonic stem

Acid Base Disorders

Acid-base disturbances are first characterized by the initial change in pH. There are four major classes of acid-base disturbances: respiratory acidosis, respiratory alkalosis, metabolic acidosis and metabolic alkalosis. The acid-base disturbances are further categorized as compensated or uncompensated. Compensation attenuates the acid-base disturbance and returns the pH
