The tricuspid and mitral valves are known as the
a. chordae tendineae.
b. semilunar valves.
c. coronary valves.
d. atrioventricular (AV) valves.

Expert Solution

a)chordae tendineae is thread like band of fibrous tissue that attach one end to edge of tricuspid and mitral valve of heart and on the other end to papillary muscle . Therefore this option is not correct .

b)semilunar valve are pocket like structures attached at the point at which the pulmonary artery and the aorta leave the ventricles. Therefore this option is incorrect

c)coronary valves are valve at the entrance of the coronary sinus into the right atrium. That control flow of blood through and from the heart. Therefore this option also incorrect.

d) Atrioventricular valve they lie between the atria and the ventricles of the heart.The mitral valve and the tricuspid valve are known collectively as the atrioventricular valves .This is correct option .

Hence the correct answer is option (d) tricuspid valve and mitral valve is called atrio ventricular valve because they lie between atria and ventricle.

In the process of producing engine valves, the valves are subjected to a first grind. Valves whose thicknesses are within the specification are ready for installation. Those valves whose thicknesses are above the specification are reground, while those whose thicknesses are below the specification are scrapped. Assume that after the first grind, 71% of the valves meet the specification, 18% are reground, and 11% are scrapped. Furthermore, assume that of those valves that are reground, 90% meet the specification, and...

Suppose the alphabet is S = {A B C D} and the known probability distribution is PA = 0.3, PB = 0.1, PC = 0.5, and PD = 0.1. Decode the Huffman coding result {11000010101110100} to the original string based on the probability distribution mentioned above. The codeword for symbol “D” is {111}. Please writing down all the details of calculation.
