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.
Since I'm not a med student and the anatomy I learned is very basic, I never learned about chordae tendineae. But from what I understand, the chordae tendineae are as important as an other part of the heart. Just imagine, without the cordae tendineae, our heart couldn't pump blood to the rest of the body. I looked this up because one of the fireman in my town's fire department passed away recently.
