Lei hulu, made from feathers. A lei (nÄ lei is the plural in the Hawaiian language) may be composed of a pattern or series of just about anything, but most commonly consists of fresh natural foliage such as flowers, leaves, vines, fern fronds, and seeds.
The chordae tendineae, or heart strings, are cord like structures that connect the Mitral and tricuspid valve to the papillary muscles. The functions of chordae tendineae are: 1) bring the right ventricular walls closer together during contraction. 2) pull the semilunar valves open to allow ventricular ejection.
The cords that attach the valve edges to the ventricle wall are called Chordae tendineae and are sometimes called heart srtings. When the right ventricle of the heart contracts, the blood pressure will push on the tricuspid valve-this stops the blood flowing into the right atria.he cords that attach the valve edges to the ventricle wall are called Chordae tendineae and are sometimes called heart srtings.
