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 papillary muscles attach to the lower portion of the interior wall of the ventricles. They connect to the chordae tendineae, which attach to the tricuspid valve in the right ventricle and the mitral valve in the left ventricle. The contraction of the papillary muscles closes these valves. When the papillary muscles relax, the valves open. Chordae Tendineae The chordae tendineae are tendons linking the papillary muscles to the tricuspid valve in the right ventricle and the mitral valve in the left ventricle. As the papillary muscles contract and relax, the chordae tendineae transmit the resulting increase and decrease in tension to the respective valves, causing them to open and close. The chordae tendineae are string-like in appearance and are sometimes referred to as heart strings.
