Answer:
upper gastrointestinal scan
Explanation:
Upper gastrointestinal series is the radiographic examination of upper gastrointestinal tract. Esophagus, stomach and then duodenum are visible on the X-ray film by the use of the liquid suspension which may be barium or water-soluble contrast.
Fluoroscopy is used during upper GI series. A continuous beam of X-ray rays is passed through body part and is transmitted to the monitor so that body part and the motion of it can be seen in every detail. <u>In upper GI series, the fluoroscopy allows radiologist to see movement of barium through esophagus, stomach, and duodenum as the person drinks.</u>
If I’m not wrong this process is called facilitated diffusion
Because they lack nucleus
I think it's true, cause an arch is produced when waves erode through a cliff.
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.
