The liquid was pulled into the small tube by capillary action.
where the blood travels from the lungs to left the atria.^^^ This answer is wrong in every salient way. Use the Wikipedia entry here: http://en.wikipedia.org/wiki/Capillary
Capillary tubes are renowned for their capillary action on liquids, i.e. they cause liquids to rise up inside them. Capillary tubes are the essence of thermometers that use a liquid indicator. In biology and the plant world, capillary tubes are fundamental to the movement of fluids through the systems of living organisms.
It is not easy to be cleaned inside.
there are no ballpoint pens in space. But you can use pencils or a fine-liner (that uses capillary suction).
The Capillary tube metering device is used primarily on small fractional-horsepower refrigeration systems that have relatively constant evaporator heat loads. These systems are hermetically sealed, leak free systems with dry-type evaporators that use a minimum of refrigerant. The capillary tube metering device is a fixed bore device, itcontrols refrigerant flow by pressure drop.
The capillary tube is the hollow opening inside the thermometer that the liquid rises or lowers in so that you can read the temperature. The bulb is the bottom portion that holds the liquid and the part you use for contact to get a temperature reading. Calvin B.
Capillary is the name for any of the tiny blood vessels which connect the arteries to the veins.The word 'capillary' comes from the Latin 'capillaris'meaning 'about, or of, hair'
Water is transferred from the roots to the leaves through the stem by capillary action.

The capillary tube acts as a restriction in the circuit between the condenser and evaporator. The liquid refrigerant in the condenser is at a high pressure, say 12 bar and it goes through the cap. tube into a region at low pressure, say 3 bar. It then evaporates, producing the cooling effect. The vapour is then compressed by the compressor and goes round again. Large refrigeration plants use an automatic valve for this function to optimise performance under different conditions. A fixed jet could be used, but the hole would be so small that it would easily be blocked. There may be other capillary tubes in some fridges, which are part of a thermometer or thermostat.
