sekrecion

Sekrecion refers to the process by which cells release substances into the extracellular space. This process is crucial for various biological functions, including communication between cells, regulation of bodily processes, and defense against pathogens. Sekrecion can occur through different mechanisms, such as exocytosis, where vesicles fuse with the cell membrane to release their contents, or through the release of soluble proteins or other molecules directly from the cell. The substances released can include hormones, enzymes, cytokines, and other signaling molecules. Sekrecion is a fundamental aspect of cell biology and plays a significant role in maintaining homeostasis and coordinating physiological responses within an organism.
