We found that, in general, the distributions of alveolar size, mechanical stresses, and surface pressures in the lungs were dominated by the weight of the lung and that changing the shape of the lung or chest wall had relatively little effect. Only at high states of expansion where the lung...
The "Dynamic Chest Image Analysis" project aims to show focal and general abnormalities of lung ventilation and perfusion based on a sequence of digital chest fluoroscopy frames. An indispensable source of information recorded in the image sequence is the shapes and motions of the lungs and heart....
Sexual dimorphism in the human respiratory system has been previously reported at the skeletal (cranial and thoracic) level, but also at the pulmonary level. Regarding lungs, foregoing studies have yielded sex-related differences in pulmonary size as well as lung shape details, but different methodol...
Quantitative descriptions of normal lung shape, inter-subject variability, and age-related differences are important for several reasons. First, diseases with age-related prevalence that affect the lung tissue can develop with a regional preference; for example, preferentially apical for emphysema as a ...
The blood,the carrier of these substances,is pumped through a closed system of each other.From the right atrium,blood flows to the right ventricle,which puups it thought the vessels of the lungs-the lesser.答案 1、这些骨头中保留的元素使这些动物的身体在需要的时候能够活动.2、一个骨头的比例在...
surfaces of organs (e.g., skin cells, lining of the lungs, intestines) must adhere to substrates and to each other under a wide variety of circumstances; their adhesion properties can be regulated by the cell which simultaneously senses the chemical and mechanical properties of its environment....
发明人: J Pannekamp 摘要: Method for digitally describing the shape of a geometrical object in which an external force is chosen that would act on the object to cause a given deformation. For implementation of the method Hooke's law linking strain to stress is used.收藏...
part of the immune system, puts patients at risk for dangerous infections. A pileup in the lungs can produce fevers and difficulty breathing. A clog near the eye can cause vision problems and retinal detachment. And if the obstructed vessels supply the brain the patient could even suffer a ...
