Stroma: the basis of the organ
Stroma is a connective tissue framework that forms the basis of an organ and supports its functional tissue, such as parenchyma. The stroma plays an important role in ensuring the structural integrity of the organ and maintaining its functions.
An example of stroma is the porous matrix of protein strands inside a red blood cell, which contains the coloring pigment of the blood - hemoglobin. This allows red blood cells to store and transport oxygen throughout the body.
Another example of stroma is the connective tissue that makes up the cornea of the eye. It is a transparent medium that acts as a lens and plays an important role in the process of refraction of light in the eye.
The stroma also plays a key role in many other organs, such as plant leaves, where it provides structural support and holds chloroplasts in place, allowing plants to carry out photosynthesis.
In conclusion, stroma is an important component of organs and tissues that ensures their structural integrity and functionality. Without stroma, organs and tissues would not be able to perform their functions with the same efficiency and accuracy as they currently do.
The stroma is the connective tissue framework or framework of an organ that supports the functional tissue (parenchyma) within it. The stroma is an important part of the structure of many organs and tissues, including blood vessels, skin, bones, lungs, liver and others.
The stroma of red blood cells, for example, is a porous framework of protein threads located inside red blood cells, where the coloring pigment - hemoglobin - is located. The corneal stroma of the eye, on the other hand, consists of transparent connective tissue that forms the basis of the cornea and protects the eye from damage.
Overall, the stroma plays an important role in maintaining the structural integrity and functionality of organs and tissues. It provides support to the parenchyma, which performs various functions such as hormone production, metabolism or protection from external influences.
However, disturbances in the stroma can lead to various diseases and pathologies. For example, in blood vessel diseases such as atherosclerosis, changes in the stroma lead to the formation of plaque on the vessel walls, which can lead to impaired blood flow and other health problems.
In addition, abnormalities in the corneal stroma can lead to various eye diseases such as keratoconus or corneal dystrophy. In such cases, restoring normal stromal structure may help improve vision and prevent further development of the disease.
Thus, stroma is an important component of many organs and tissues and plays a key role in their functioning. Disturbances in its structure can lead to various health problems, so it is important to understand its role and significance for human health.
Stroma is not a cellular or tissue material, but a universal substrate that fills the intercellular spaces of a particular organ or organ system. When talking about functional tissue, for example, parenchyma, then in order to avoid confusion, it is clarified from the very beginning which parenchyma is meant - exocrine or endogenous. In the context of this article, we will understand parenchyma only as an endogenous, actually tissue
