low pressure
The inner fold pleura closest to lung tissue is called the visceral pleura.
The condition where the lung tissue collapses is called atelectasis. This occurs when alveoli in the lungs deflate, leading to reduced gas exchange and potential respiratory issues. Atelectasis can be caused by various factors such as blockage of airways, pressure on the lungs, or underlying lung diseases.
If the pressure in the lung is greater than atmospheric pressure, air will flow out of the lungs in order to equalize the pressure. This is called exhalation or breathing out.
It is the tissue which surrounds and supports the actually functional lung tissue
Lung tissue is alternatively called parenchyma. It is actually made up of clusters of soft, spongy air sacs known as lobules.
In lungs there are several types of tissues, depending of what part of the lung you're referring to. It gets thinner and thinner from bronchi to alveoli, for example with just one layer of cells in these last ones.
Inhalation is caused by a reduction in air pressure inside the lungs by increasing their volume through diaphragm contraction. Exhalation is cause by the decreasing lung volume upon relaxation of the diaphragm. The elasticity of lung tissue causes the lung to retract, increasing the internal lung pressure above atmospheric pressure and the air moves out.
Pathological lung sections differ from normal lung tissue. Pathological lung sections include the pathological tissues of fibronectin, collagens, and proteoglycans.
Alveoli (pulmonis) or just alveoli.
Fluid located in the lung tissue is called atriovacural fluid. (pronounced atri-o-va-cural) This fluid builds up as a result of many factors; including smoking, bad diet, high cholesterol and oral sex.
A deep breath for lung ventilation is called a "sigh." It involves a larger intake of air to help expand the lung tissue and improve oxygen exchange. Sighs can happen involuntarily as a reflex to maintain lung function.
Pneumatic changes in the lungs refer to the expansion and contraction of the lung tissue in response to changes in air pressure during breathing. The diaphragm and intercostal muscles work together to increase lung volume during inhalation, creating negative pressure that draws air into the lungs. During exhalation, the muscles relax, and the elastic recoil of the lung tissue expels air out of the lungs.
