Vaskulárním

Vaskulárním is an instrumental form of the Czech adjective vaskulární, which means vascular or related to vessels. The term is used in scientific and medical contexts as well as in botany, and it appears in phrases describing processes, systems, or structures associated with vessels.

In human and animal anatomy and medicine, vaskulární refers to vessels that transport fluids through the body, primarily blood vessels and lymphatic vessels. The vascular system includes arteries, veins, capillaries, and the heart as the central pump. Vaskulární conditions or onemocnění are diseases affecting these vessels, such as atherosclerosis, aneurysms, stroke, or chronic venous insufficiency. The term is often used in clinical descriptions, imaging reports, and research to denote involvement of the circulatory or lymphatic networks.

In botany, vaskulární rostliny (vascular plants) are plants that possess specialized conductive tissues, namely xylem and phloem, enabling efficient transport of water, minerals, and photosynthetic products. This group includes ferns, conifers, and flowering plants. Non-vaskulární (non-vascular) plants, such as bryophytes (mosses, liverworts, hornworts), lack these tissues and have limited size and transport capabilities. The distinction between vaskulární and non-vaskulární plants reflects important evolutionary steps in plant biology and ecology.

Etymologically, vaskulární derives from a root related to vessels, from Latin vasculum or a related form, and has been integrated into Czech scientific terminology. In usage, vaskulárním is chosen to fit grammatical case requirements of Czech and appears in sentences describing relationships to vessels or systems.
