érszövethöz
érszövethöz is a term derived from the Hungarian words "ér" (blood vessel) and "szövet" (tissue), used to indicate that a structure or tissue is supplied with, contains, or is related to blood vessels. In anatomical and pathological contexts it is often employed to describe organs, tissues, or lesions that possess a rich vascular supply or that are nourished by blood vessels. The term can apply to whole organs, such as the liver or kidneys, which are intrinsically vascularized, as well as to more specific structures like the dermis of the skin or the internal mucosal layers of hollow organs. It is also utilized in describing tumours, for instance "érszövethöz szűkítés" (vascular constriction) or "érszövethöz dysplázia" (vascular dysplasia), indicating alterations in the blood vessel patterns within the lesions. In surgical descriptions, "érszövethöz választ" denotes a resection that preserves the vascular integrity, and in radiology, "érszövethöz jelölés" refers to detailing of blood vessels when imaging tissues. The concept is important for understanding tissue perfusion, the delivery of oxygen and nutrients, and the removal of metabolic waste. Vascularized tissues are also major sites for blood cell production; for example, immunologic responses in vascularized lymphoid organs depend on blood flow. The presence or absence of vascularization informs diagnostic, therapeutic, and prognostic decisions for various medical conditions, including cancers, vascular malformations, and ischemic injuries. The term erősít a vitaigán die microbial and immune response as blood flow and the associated vascular structures are critical in enabling circulation of immune cells and molecules.
