There are primarily three types of capillary tubes: open capillary tubes, closed capillary tubes, and capillary tubes with a tapered end. Open capillary tubes are used in applications such as blood sampling, while closed capillary tubes are often employed in thermometers or pressure measurement. Tapered capillary tubes facilitate fluid movement and can enhance the flow rate. Each type serves specific functions based on the requirements of the application.
They allow capillary walls to open and become leaky.

Capillary beds open and close in response to the body’s metabolic needs and local tissue demands for oxygen and nutrients. Vasodilation occurs in response to increased carbon dioxide, low oxygen levels, or other signaling molecules, allowing blood flow to increase and capillary beds to open. Conversely, vasoconstriction can occur when there is a need to redirect blood flow to vital organs or during rest, causing capillary beds to close. This dynamic regulation helps maintain homeostasis and ensures that tissues receive adequate blood supply based on their activity levels.
