capillaries, plural;
  1. Any of the fine branching blood vessels that form a network between the arterioles and venules

  2. A tube that has an internal diameter of hairlike thinness

  1. (capillary) a tube of small internal diameter; holds liquid by capillary action
  2. (capillary) of or relating to hair
  3. (capillary) any of the minute blood vessels connecting arterioles with venules
  4. Capillaries are the smallest of a body's blood vessels and are part of the microcirculation. They are only 1 cell thick. ...
  5. (capillary) Any of the small blood vessels that connect arteries to veins. Their walls are composed of a single layer of cells which allows molecules such as oxygen, water and lipids to pass through them by diffusion and enter the tissues. ...
  6. (Capillary) Microscopic blood vessels where the gas exchange takes place between the bloodstream and the tissues or the air in the lungs.
  7. (Capillary) The smallest of the body's blood vessels. Oxygen and glucose pass through capillary walls and enter the cells. Waste products such as carbon dioxide pass back from the cells into the blood through capillaries.
  8. (Capillary) Very slender and hair-like.
  9. (Capillary) a tiny blood vessel that connects an artery to a vein
  10. (capillary) A minute blood vessel which connects an arteriole and venule, forming a network in nearly all parts of the body and effecting a transition from arterial to venous blood flow.
  11. (CAPILLARY) The name given to the thin tube attached to the bulb which transmits the bulb pressure changes to the controller or indicator. ...
  12. (CAPILLARY) A copper tube with a very small inside diameter. Its function in the refrigerant system is to separate the High Pressure (condenser) side from the Low Pressure (evaporator) side, by providing a calibrated restriction and a resulting pressure drop.
  13. (CAPILLARY) movement of water  through small gaps due to adhesion and surface tension.
  14. (Capillary) A phenomenon of soil which allows water to be absorbed either upward or laterally.
  15. (Capillary) A tube or vessel extremely fine or minute.
  16. (Capillary) A tube which exhibits a length to diameter ratio ³ 400. In most cases the tube has an internal diameter in the range of a few thousandths of an inch, which causes the characteristic elevation or depression of liquids.
  17. (Capillary) In cement paste, any space not occupied by anhydrous cement or cement gel. Air bubbles, whether entrained or entrapped, are not considered as part of the cement paste.
  18. (Capillary) Syphoning action, raising water to the plant from an absorbent surface such as sand or a flannel-type cloth. Lamp wicks can also be used to transfer water from a container to plants situated at a higher level.
  19. (Capillary) The smallest division of the blood circulation system. They are very thin walled blood vessels in which oxygen is in close proximity to the tissues and unlatches from haemoglobin. ...
  20. (Capillary) any of the tiny, thin walled tubes that carry blood between arteries and veins, location of gas and nutrient exchange.
  21. (Capillary) in anatomy, a thin-walled tiny blood vessel, averaging 8 microns in diameter.
  22. (Capillary) the action by which the surface of a liquid (where it is in contact with a solid) is elevated or depressed, depending upon the relative attraction of the molecules of the liquid for each other and for those of the solid.
  23. (capillary) (sometimes capillaceous) referring to the fine, usually smooth pappus setae, e.g. in Reichardia (tribe Lactuceae), and commonly in members of the tribe Senecioneae.
  24. (capillary) the smallest blood vessel (5-20 micrometres in diameter). It has a wall only one cell thick, so oxygen, carbon dioxide, salts etc. can be exchanged between the blood and body tissue.
  25. tiny blood vessels between arteries and veins that distribute oxygen-rich blood to the body.
