capillary
Microscopic blood tube
Capillary describes things resembling hair in fineness or slenderness.
The capillaries are the body's tiniest blood vessels—microscopic tubes connecting arteries to veins where oxygen and nutrients pass into tissues.
Capillary action is the tendency of liquid to rise or be drawn through narrow spaces against gravity, as when water climbs a paper towel or plant stems pull moisture from soil.
