What values are opening or Closing with S1 and S2,
When does S3 occur in the Cycle and S4
What is a pulse deficit.
On the Diagram:
Name Each Area and the value that is not hard and The Land Marks
Explain what value is auscultated on the chest
1)
S1 is the first heart sound (lub) produced due to the closure of AV valve ( mitral valve +tricuspid valve)
S2 is the second heart sound(dubb) produced due to the closure of Semilunar valves(Pulmonary valve +Aortal valve)
2)
S3, also known as the ventricular gallop, occurs just after S2 when the mitral valve opens, allowing passive filling of the left ventricle.A S3 can be a normal finding in children, pregnant females and well-trained athletes.
The fourth heart soundor atrial diastolic gallop is a low-pitched sound coincident with late diastolic filling of the ventricle due to atrial contraction.Although it is also called the atrial sound, and its production requires an effective atrial contraction, the fourth heart sound is the result of vibrations generated within the ventricle.It is heard in lateral position.it will be absent in atrial fibrillation.
3) pulse deficit is the difference in a minute's time between the number of beats of the heart and the number of beats of the pulse observed in diseases of the heart like atrial fibrillation.
4)A - AOTIC AREA- it represent the aortic valve ans is located at right of the sternal border in the second intercostal space.
P- pulmonary area- represent the pulmonary valve aand is locared on the left side of sternum in the fourth intercostal space
E- The fifth is ERBS POINT located left of the sternal border in the third intercostal space,Cardiac murmurs caused by aortal insufficiency and mitral stenosis can in particular be heard.
M-MITRAL AREA- located on the apex of the heart. represent the mitral valve.

Given the following sequence of instructions: lw $s2, 0($s1) //1 lw $s1, 40($s3) //2 sub $s3, $s1, $s2 //3 add $s3, $s2, $s2 //4 or $s4, $s3, $zero //5 sw $s3, 50($s1) //6 a. List the read after write (current instruction is reading certain registers which haven’t been written back yet) data dependencies. As an example , 3 on 1 ($s2) shows instruction 3 has data dependency on instruction 1 since it is reading register $s2. b. Assume the 5...
