Changes in cell number, size, and function associated with aging are likely to impact on lung physiology, metabolism, and immunity. Such changes could significantly alter the normal functions of the lung and its susceptibility to injury. Aging of canine lungs has many similarities to that seen ...
Oxygen from the lungs is required for the production of energy for all biological processes and carbon dioxide is a by-product of energy release and metabolism. The techniques of nuclear medicine can provide a window through which the normal functioning of lung (physiology) and the abnormal ...
Gas exchange is the vital function of the lungs. It occurs in the alveoli, where oxygen and carbon dioxide diffuse across the alveolar epithelium and the c... Manfred,Kopf,Christoph,... - 《Nature Immunology》 被引量: 173发表: 2015年 Decline of lung function and development of chronic air...
Is the bronchus-associated lymphoid tissue (BALT) an integral structure of the lung in normal mammals, including humans? In the respiratory tract, lymphoid aggregates with a specialized epithelium have been called bronchus-associated lymphoid tissue (BALT) and compared to the......
It has been shown that measures of inhomogeneity detect signs of the disease earlier than spirometry, the most common form of lung function test. There is however, currently no "gold standard" method for assessing the inhomogeneity of the lungs. A common technique for investigating inhomogeneity ...

Based on the results of lung function tests, participants were classified into three groups: the normal lung function group included patients with FEV1 ≥ 80% of predicted and FEV1/FVC ≥ 0.7; the PRISm group included patients with FEV1 < 80% of predicted value and FEV1/FVC ...
The size, shape and volumes of individual lungs and lobes can be estimated from plain chest radiographs. Corresponding information about individual segments, and about lobes not delineated by normal X-ray, can be obtained using radio-active krypton 81m and a gamma camera during otherwise routine ...
The cardiovascular system (CVS) is made up of the heart, blood vessels, and blood. The fundamental function of CVS is to transport substances to and from all parts of the body. The heart is the major pumping organ, pressurizing blood for circulation thro
In humans, the respiratory tract is divided into the upper airways (nasal cavity, pharynx, and larynx) and the lower airways (trachea, bronchi, bronchioles, and alveoli). The lungs consist of the bronchi, bronchioles, and alveoli. The primary function of the respiratory tract is to efficiently...
