Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain parenchyma in animal and plant senses, relay the parenchyma of major organs from anatomy references, describe parenchymal disease and imaging, and distinguish parenchyma from stroma, interstitium and other tissue types.

The functional tissue of an organ, as distinguished from the supporting connective tissue or stroma, such as the alveoli and gas-exchanging tissue of the lung, the hepatocytes of the liver, the nephrons of the kidney, the lymphoid tissue of the spleen and the cortex and medulla of the thymus; in plants, parenchyma is the ground tissue of thin-walled living cells that fills leaves, stems, roots and fruits; parenchymal damage is a central concept in pathology.

What it is for: Not applicable; a tissue concept.

It can be explain the concept; relay organ parenchyma; describe disease and imaging; distinguish from stroma.

Distinguishing features

Function-bearing tissue

Organ-specific

Contrast with stroma

Plant homonym

What it looks like

Not a visible object without microscopy; the working tissue of organs.

Physical character

liver parenchymal cells: about 70-80 percent - hepatocytes by volume

plant parenchyma cell wall: thin primary type

How it is recognised

Functional tissue of an organ

Lung, liver, kidney, spleen and thymus parenchyma; plant ground tissue

Stroma is the supporting framework; interstitium is the space between cells; epithelium is a tissue type

What the second pass must settle

  • Should lung parenchyma and plant parenchyma be separate entries?
  • How should anatomy references be linked?
  • The registry entry has merged aliases naming organ-specific parenchyma and a cell type; should they be split off?
