Select the correct statement about the physical factors influencing pulmonary ventilation.

Medicine
1 answer:
Yanka [14]3 years ago
4 0

Answer:

Option (b).

Explanation:

Pulmonary ventilation is the mechanism of respiration in which the oxygen is inhaled in the body and carbon dioxide is exhaled out due to the pressure difference in the lungs and the environment.

The surface tension in the alveoli is decreased by the presence of surfactant. The increase in the surface tension of the alveoli increase the force that will require the additional muscles to work properly.

Thus, the correct answer is option (b).

Sound is more effectively transmitted into a stethoscope by direct contact than through the air, and it is further intensified b
zhenek [66]

Answer: Δβ = 28.5278 dB

Explanation:

from the question we are given that;

the sound gathering area Ga = 15.0 cm²

total area Ae = 0.800 cm²

efficiency ε = 38 %

therefore we have that the effective gathering area of the stethoscope is;

As = ε Ga

As = 38 % × 15 = 5.7 cm²

But I ∝ 1/A

where Ie/Is = As/Ae

Ie/Is = 5.7/0.800 = 7.125

given that we are to assume that  sound is transmitted into a stethoscope 100 times, this gives

I'e/I's = Ie/Is × 100 = 7.125 × 100 = 712.5

Δβ = βe - βs = (10dB) log (I'e/Io) - (10dB) log (I's/Io)

Δβ = (10dB) log (I'e/I's)

Δβ = (10dB) log (712.5) = 28.5278

Δβ = 28.5278 dB

Finger [1]

The nurse should assess the client's ability to stand or sit.

Lung cancer is a type of cancer that begins in the lungs. Your lungs are two spongy organs in your chest that take in oxygen when you inhale and release carbon dioxide when you exhale.

Lung cancer is the leading cause of cancer deaths worldwide.

People who smoke have the greatest risk of lung cancer, though lung cancer can also occur in people who have never smoked. The risk of lung cancer increases with the length of time and number of cigarettes you've smoked. If you quit smoking, even after smoking for many years, you can significantly reduce your chances of developing lung cancer
