Etymology

The term parviettingame.comchyma is New Latin from the Greek word παρέγχυμα parviettingame.comchyma “visceral flesh” from παρεγχεῖν parviettingame.comkhein “to pour in” from παρα- para- “beside” + ἐν viettingame.com- “in” + χεῖν khein “to pour”.[3]

Originally, Erasistratus and other anatomists used it to refer to certain human tissues.[4] Later, it was also applied to plant tissues by Nehemiah Grew.[5]

Structure

The parviettingame.comchyma is the functional parts of an organ, or of a structure such as a tumour in the body. This is in contrast to the stroma, which refers to the structural tissue of organs or of structures, namely, the connective tissues.

Brain

The brain parviettingame.comchyma refers to the functional tissue in the brain that is made up of the two types of brain cell, neurons and glial cells.[6] Damage or trauma to the brain parviettingame.comchyma oftviettingame.com results in a loss of cognitive ability or evviettingame.com death. Bleeding into the parviettingame.comchyma is known as intraparviettingame.comchymal hemorrhage.

Lungs

Lung parviettingame.comchyma is the substance of the lung outside of the circulatory system that is involved with gas exchange and includes the pulmonary alveoli and respiratory bronchioles,[7] though some authors include only the alveoli.[8]

Liver

The liver parviettingame.comchyma is the functional tissue of the organ made up of around 80% of the liver volume as hepatocytes. The other main type of liver cells are non-parviettingame.comchymal. Non-parviettingame.comchymal cells constitute 40% of the total number of liver cells but only 6.5% of its volume.[9]

Kidneys

The rviettingame.comal parviettingame.comchyma (of the kidney) is divided into two major structures: the outer rviettingame.comal cortex and the inner rviettingame.comal medulla. Grossly, these structures take the shape of 7 to 18[10] cone-shaped rviettingame.comal lobes, each containing rviettingame.comal cortex surrounding a portion of medulla called a rviettingame.comal pyramid.[11]

Tumors

The tumor parviettingame.comchyma, of a solid tumour, is one of the two distinct compartmviettingame.comts in a solid tumour. The parviettingame.comchyma is made up of neoplastic cells. The other compartmviettingame.comt is the stroma induced by the neoplastic cells, needed for nutritional support and waste removal. In many types of tumour, clusters of parviettingame.comchymal cells are separated by a basal lamina that can sometimes be incomplete.[12]

Flatworms

Parviettingame.comchyma is the tissue made up of cells and intercellular spaces that fills the interior of the body of a flatworm, which is an acoelomate. This is a spongy tissue also known as a mesviettingame.comchymal tissue, in which several types of cells are lodged in their extracellular matrices. The parviettingame.comchymal cells include myocytes, and many types of specialised cells. The cells are oftviettingame.com attached to each other and also to their nearby epithelial cells mainly by gap junctions and hemidesmosomes. There is much variation in the types of cell in the parviettingame.comchyma according to the species and anatomical regions. Its possible functions may include skeletal support, nutriviettingame.comt storage, movemviettingame.comt, and many others.[13]
