Starling
Definition:
(n.) Any passerine bird belonging to Sturnus and allied genera. The European starling (Sturnus vulgaris) is dark brown or greenish black, with a metallic gloss, and spotted with yellowish white. It is a sociable bird, and builds about houses, old towers, etc. Called also stare, and starred. The pied starling of India is Sternopastor contra.
(n.) A California fish; the rock trout.
(n.) A structure of piles driven round the piers of a bridge for protection and support; -- called also sterling.
Example Sentences:

(3) Properly timed atrial systole may alter systolic performance by the mechanism of Starling's law of the heart, which states that the extent of systolic myocardial fiber shortening is dependent on the degree of diastolic fiber stretch, or preload.

(9) Possible mechanisms causing the observed biphasic lymph flow response to capillary pressure elevation are: 1) changes in Starling forces oppose an increase in capillary pressure; 2) the rate of change in tissue fluid pressure affects lymph flow to a greater extent than does the absolute change in tissue fluid pressure; or, 3) the lymphatics empty upon elevation and refill as the capillaries filter.
