Which term describes an accumulation of air or gas in the pleural space that causes the lung to collapse?
Hemothorax (hee-moh-THOH-racks)hem/o means blood , and -thorax means chestThe accumulation of blood in the pleural cavity in commonly referred to as a Hemothorax, as opposed to air build up in the cavity called a pneuomothorax. Typically, to correct a hemothorax one needs the insertion of a chest tube and the blood must be drained from the cavity.It is usually caused from an injury, especially blunt trauma. It can also occur in patients who suffer a pulmonary infarction (death of a section of lung), patients who have had a type of chest surgery, patients with lung or pleural cancer, etc. Rarely, a blood vessel ruptures into the pleural space when no injury has occurred, or a bulging area in the aorta (aortic aneurysm) leaks blood into the pleural space.
Why there is negative pressure in pleural cavity?
Pleural pressure is negative (lower than alveolar pressure or barometric pressure) because of a "suction effect" caused by lung recoil. As the lungs recoil elastically, the inner and outer pleural membranes tend to be pulled apart but fluid within the pleural cavity keeps the inner and outer pleural membranes close together. This pulling force decreases the pressure between the inner and outer membranes lining the pleural cavity - an effect that can be appreciated by stacking several plastic cups together, submersing the stack in soapy water ensuring that the spaces between the cups fill with water, and then lift the stack of cups out of the water and try to pull the cups apart. A suction effect will occur producing negative pressure in fluid-filled spaces between the cups as you attempt to pull them apart. The fluid-filled space between the cups is like the fluid-filled space in the pleural cavity. That is why pleural pressure is negative.
What is a tympanic sound?
A tympanic sound is a drum-like or resonant sound produced when a hollow body cavity, such as the abdomen, is tapped. It indicates the presence of air or gas within that cavity. Tympanic sounds are commonly assessed during physical examinations to help diagnose various medical conditions.
What happens to the air in the nasal cavity?
The air in the nasal cavity is warmed, filtered, and humidified before it reaches the lungs. This process helps protect the delicate lung tissue and ensures optimal conditions for gas exchange. Additionally, olfactory receptors in the nasal cavity allow for the sense of smell.
What is charcoal cavity test?
The charcoal cavity test is a method used to test for the presence of hydrogen gas. To conduct the test, a sample is mixed with sulfuric acid, and the resulting hydrogen gas is passed through a tube containing charcoal. If hydrogen gas is present, the charcoal will become silver-black in color.
What is pnuemothorax?
the presence of air or gas in the cavity between the lungs and the chest wall, causing collapse of the lung
What is the medical term meaning the collapse of part or all of the lung?
Atelectasis (at-ee-LEK-tah-sis) is the collapse of part or all of the lung by the blockage of the air passages or by very shallow breathing (atel means incomplete, and -ectsis means stretching or enlargement). "Pneumothorax" is actually the presence of free air or gas in the pleural cavity.

What is pneumothorax-?
Air in the chest (Thorax) causes the lung to collapse. This can be spontaneous or after chest injuries

Increasing the size of the thoracic cavity causes?
Increasing the size of the thoracic cavity allows for the lungs to expand, creating negative pressure inside the chest cavity. This negative pressure pulls air into the lungs, facilitating inhalation. Additionally, it helps to maintain airflow and efficient gas exchange in the respiratory system.
What is in pulmonary cavity?
The pulmonary cavity houses the lungs, which are essential for breathing and gas exchange in the body. It is located within the thoracic cavity and is surrounded by the rib cage to provide protection and support to the lungs. The pulmonary cavity also contains other structures such as blood vessels, bronchi, and connective tissues that support the function of the lungs.

A collection of air or gas outside the lung and the chest wall?
You may be referring to a pneumothorax. This is a collection of air in the pleural cavity (between the lung and the chest wall). Symptoms include: pain and shortness of breath (dyspnea). In severe cases, if left untreated it can lead to cardiac arrest, but sometimes small spontaneous ruptures can heal themselves without treatment.
What is the special breathing system that birds have?
The respiratory system of birds differs significantly from that found in mammals, containing unique anatomical features such as air sacs. The lungs of birds also do not have the capacity to inflate as birds lack a diaphragm and a pleural cavity. Gas exchange in birds occurs between air capillaries and blood capillaries, rather than in alveoli.
What happens to the air in the nasal cavity?
The air in the nasal cavity is warmed, filtered, and humidified before it reaches the lungs. This process helps protect the delicate lung tissue and ensures optimal conditions for gas exchange. Additionally, olfactory receptors in the nasal cavity allow for the sense of smell.
