👉 The bundle fluid, also known as the bundle vessel or collateral artery, is a critical component of the microcirculation that connects arterioles to venules or capillaries. It forms when a branch of an arteriole merges with a venule or capillary, creating a network that facilitates the exchange of nutrients, gases, and waste products between the blood and surrounding tissues. This fluid-rich network ensures efficient perfusion and supports the metabolic needs of tissues by maintaining a balance between blood flow and tissue demand.
