Answer:
B) The "lub-dub" sound originates from blood turbulence through the heart.
Explanation:
The systole and diastole in the heart produce the lub and dub sound in the heart.
The systole represents the contraction of both left and right ventricles and pumps the blood to the body and the right ventricle to the lungs. This involves the opening and closing of the valves. The closing of the atrioventricular valves produces lub sound.
At the end of the systole or ventricular contraction or when the blood has been pumped to the aorta and the pulmonary valves then the semilunar valves present in the aorta and pulmonary closes. This produces a sound dub.
Therefore,lub dub is associated with the physical contraction of the heart but not the turbulence of the blood.
Thus, the selected option is the correct answer.
The type of energy that comes from the movement of small particles is thermal energy, as the movement of particles produces thermal energy as a result.
<h3>What is it called or particle motion?</h3>
Concept Brownian is the random motion of particles in a fluid (liquid) as a consequence of all changes such as the gas or movement of those present in the fluid.
With this information, we can conclude that On the motion of small suspended particles within liquids at rest, as required by the kinetic molecular theory of heat
