Answer:

A psychrometer is a simple type of hygrometer. A hygrometer is an instrument which is used for measuring the humidity in an environment.

A psychrometer is a device which uses the difference in readings between a wet-bulb thermometer a dry bulb for measuring the relative humidity.

The bulb that is wet will cool by evaporation to the "dew point". Comparing this wet bulb to the dry bulb (the general air temperature) on a comparative chart will yield the approximate relative humidity.

Which of the following is NOT true regarding the sounds associated with the heart? Select one: a. The "lub-dub" sound originates
Valentin [98]

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.
