GRANULATION TISSUES Meaning and
Definition
-
Granulation tissue is a type of healing tissue that forms during the later stages of wound healing. It is composed of small blood vessels, collagen fibers, and inflammatory cells that fill in the wound and promote the regeneration of damaged tissue.
When a wound or injury occurs to the body, the normal healing process involves several stages. One of the key stages is the formation of granulation tissue. As the wound begins to heal, blood vessels around the injury site dilate and become leaky, allowing inflammatory cells, such as neutrophils and macrophages, to migrate to the area. These cells release growth factors and cytokines that stimulate the proliferation of fibroblasts, specialized cells that produce collagen, a protein responsible for the strength and elasticity of connective tissue.
As fibroblasts multiply and migrate to the wound site, they start producing collagen fibers, which provide the framework for the formation of granulation tissue. Capillaries also grow into the tissue, supplying it with oxygen and nutrients. Granulation tissue appears pink or red due to increased blood flow and is often characterized by its granular, minced meat-like appearance.
The main function of granulation tissue is to fill in the wound space, provide structural support, and serve as a scaffold for the regeneration of new tissue. Over time, the tissue undergoes remodeling, where collagen fibers become more organized and blood vessels regress, leading to the formation of mature scar tissue.
In summary, granulation tissue is a vital component of the wound healing process, serving as the foundation for tissue repair and regeneration.

Etymology of GRANULATION TISSUES
The word "granulation tissues" comes from the combination of two separate words: "granulation" and "tissues".
1. Granulation: The word "granulation" originated from the Latin word "granulum", which means small grain or seed. In the medical field, "granulation" refers to the process of small, rounded masses or granules forming in a wound during the healing process. Granulation occurs when fibroblasts produce collagen and other proteins that help in repairing the damaged tissue.
2. Tissues: The word "tissues" derives from the Old French word "tissu", meaning "a piece or a patch". It further stems from the Latin word "texere", which means "to weave". In the medical context, "tissues" refer to the specialized cells that work together to perform a specific function in an organism.
