<h3>What is way of testing medicines?</h3>

In a laboratory, drugs are first subjected to non-human tests. These laboratory tests are performed to determine a level of safety.

The results of these tests are then submitted to the United States Food and Drug Administration (FDA), which determines whether the treatment is safe enough to be studied in human volunteers.

There are various phases involving discovery, clinical trial, review, and safety monitoring.

If intrapulmonary pressure was 760 mm hg, what would you expect the intrapleural pressure to be?
Natasha_Volkova [10]
<h3><u>Answer;</u></h3>

756 mm Hg

<h3><u>Explanation;</u></h3>
  • Intrapleural pressure is the pressure of the air within the pleural cavity, between the visceral and parietal pleurae. This pressure changes during different phases of breathing.
  • <em><u>Due to certain characteristics of the lungs, the intrapleural pressure is always lower than, or negative to, the intra-alveolar pressure. It  remains approximately –4 mm Hg throughout the breathing cycle.</u></em>
  • <em><u>Therefore; if the intrapulmonary pressure was 760 mm hg then the intrapleural pressure will be (760 -4) mm Hg, that is 756 mm Hg</u></em>
