Parenchyma

Parenchyma is the functional part of an organ, in contrast to its supporting part (connective tissue framework) (stroma).

Parenchyma is a collection of cells and intercellular substance that ensures the performance of specialized organ functions. For example, the liver parenchyma consists of hepatocytes that perform the functions of synthesis, detoxification and excretion. The kidney parenchyma includes nephrons that filter blood.

Unlike the parenchyma, the stroma of the organ primarily performs supporting and trophic functions. The stroma is represented by connective tissue and ensures the integrity of the organ. Thus, the parenchyma and stroma complement each other, ensuring the normal functioning of the organ.



Parenchyma is one of the functional parts of many organs of living organisms. It is different from the supporting part of the organ, which is made up of connective tissue called stroma.

Parenchyma consists of cells that perform specialized functions necessary for the functioning of the body. Parenchyma cells can have different shapes and sizes, depending on the function they perform. For example, the parenchyma cells of a plant leaf may be flat and wide to maximize the use of light for photosynthesis, while the parenchyma cells of a plant root may be narrow and long to quickly penetrate the soil and absorb nutrients.

Organs that contain parenchyma include leaves, stems, roots, fruits, seeds, liver, lungs and many others. In leaves, parenchyma cells perform the function of photosynthesis as well as storage of nutrients. In stems, parenchyma cells can perform the function of storing reserve substances, as well as transporting water and nutrients between the root system and leaves. In roots, parenchyma can perform the function of absorbing water and minerals from the soil.

Parenchyma cells may be completely separable from each other or have openings called intercellular spaces. Intercellular spaces allow the free flow of gases, liquids and other substances within organ tissues.

In addition, parenchyma cells have the ability to divide and regenerate, which allows them to restore damaged tissue. This ability can be used in medical practice to treat various diseases.

In conclusion, parenchyma is an important functional part of many organs of living organisms. Its cells perform various functions, such as photosynthesis, storage of nutrients, absorption of water and minerals, transport of substances between different parts of organs, etc. In addition, parenchyma cells have the ability to regenerate, which makes them important in medical practice.



Parenchyma is the functional part of an organ, in contrast to its supporting part (connective tissue framework) (stroma).

Parenchyma consists of cells that perform specialized functions of a given organ. For example, in the liver parenchyma is formed by hepatocytes, in the kidneys by nephrons, and in the lungs by alveolar cells.

Unlike parenchyma, the stroma of an organ consists of connective tissue and performs a supporting function. The stroma provides the parenchyma with support and nutrition.

Thus, the parenchyma is the working part of the organ, and the stroma is its frame. The ratio of parenchyma and stroma varies in different organs, but the parenchyma always predominates because it performs the main function of the organ.



Parenchyma is the functional part of an organ that is distinct from its supporting stroma. The stroma is a connective tissue framework that supports and protects the organ. Parenchyma is the functional part of the organ and performs its main functions.

Parenchyma can be of various types and located in different organs. For example, in the lungs, the parenchyma consists of air alveoli, which provide gas exchange between air and blood. In the liver, the parenchyma is the liver cells that are involved in the metabolism and synthesis of bile. In the kidneys, the parenchyma is formed by nephrons, which filter the blood and produce urine.

The functional part of an organ differs from its stroma in many ways. Parenchyma usually has a higher density and more complex structure than stroma. It can also have different shapes and sizes depending on the function of the organ.

In addition, the parenchyma has its own circulatory system, which provides it with oxygen and nutrients. While the stroma usually receives its nutrition from common blood vessels, the parenchyma receives blood directly from its own capillaries.

Thus, parenchyma is an important functional part of any organ and plays a key role in its functioning. Its structure and function depend on the specific functions of the organ and can be different in different organs and tissues.
