Atelectasis: Atelectasis is a complete or partial collapse of the entire lung or area of the lung. It occurs when the tiny air sacs (alveoli) within the lung become deflated or possibly filled with alveolar fluid. . General anesthesia is a common cause of atelectasis. It changes your regular pattern of breathing and affects the exchange of lung gases, which can cause the air sacs (alveoli) to deflate.
Conditions when atelectasis occurs: There are four primary causes of atelectasis: hypoventilation, airway obstruction, airway compression, and adhesions.
Hypoventilation
Hypoventilation, or breathing at an abnormally slow rate, is common during surgery, especially with general anesthesia, or when a person is placed on a respirator. The very act of shallow breathing prevents air from getting to the alveoli, causing the air sacs to deflate and collapse.
Airway Obstruction
Airway obstruction may be caused when something blocks a passage either inside the lung (like a mucus plug or a foreign object) or outside of the lungs (like a tumor which presses on the airway and causes obstruction).
Airway Compression
Compression of the airways is often caused by the buildup of fluid in the space surrounding the lungs.
Answer:
Nancy put them in developer for a short time, that is to say that the image was very clear and even though I later washed them and ran them through the fixing solution they no longer had a solution
Explanation:
The development of dental radiographs has three stages:
The first is to place the radiograph in developer, the second to wash it in water and the third to fix the image and define it with fixative.
The developer is in charge of giving the contrast to the radiographic image and the radiopaque-radiolucent colors, if the radiographic plate lasts less time or the developer is altered due to misuse / maintenance, it will not look correctly and will have a dim image appearance.
Plants convert energy from sunlight into sugar in a process called photosynthesis. Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen (Figure 2).
A quail, like most birds, is cold blooded.
