Intrapleural pressure is
Negative during expiration.
Intrapleural pressure is the air pressure in the pleural cavity
and also exists between visceral and parietal pleurae. This pressure
majorly depends on ventilation phase, the volume of the intrapleural cavity and
atmospheric pressure. During expiration, the Intrapleural pressure in the pleural cavity becomes
less negative which is commonly known as negative pressure.
Answer:
the symbol for nitrogen is N
Explanation:
Global air circulation cells move air "clockwise in the Northern hemisphere and counterclockwise in the Southern hemisphere".
<u>Answer:</u> Option B
<u>Explanation:</u>
Global circulation is defined as the global connection of winds, through which the requisite heat transport from tropical latitudes to polar latitudes carried out. Each hemisphere comprises with three cells, such as Hadley, Ferrel and Polar cell, air circulation take place in this through the complete depth of the troposphere.
The worldwide circulation cells allow passage of air in clockwise pattern in the northern hemisphere while in southern hemisphere circulate in counter-clockwise pattern from equator to poles but in different directions and at different latitudes.
