What does parenchyma mean?

In pathology, the term parenchyma refers to the tissue normally found within an organ. Specifically, it is made up of cells that carry out the specific function of the organ. As a result, the types of cells found in the parenchyma will depend on the organ being examined. For example, the parenchyma of the liver is made up primarily of specialized cells called hepatocytes. In contrast, the salivary glands are made up of specialized cells that form small structures called glands. The cells that make up the parenchyma are surrounded by a type of connective tissue called stroma which helps to hold the other cells in the organ together.
