A pig weighing around 60 kilograms will, for example, resemble a human body in many ways, including fat distribution, cover of hair and ability to attract insects. Pigs are mammals. In the living organism, energy is liberated, along with carbon dioxide, through the oxidation of molecules containing carbon. The population of lung macrophages is the main producer of inflammation mediators, such as cytokines and chemokines, which can also be secreted by other cell types. The digestive tract can be considered as a tube that starts at the mouth and finishes at the rectum (Fig.1-2). Although this last animal is definitely not a mammal, I thought that it would be interesting to look at the many parallels between them. The carcase is condemned at slaughter. We must never forget that the alveolus, the place where the respiratory exchange takes place, has contact with the exterior, so the integrity of the mucociliary apparatus and the functionality of the macrophages is fundamental to maintain the homeostasis of the respiratory function.

Similarities Differences The pig's cardiovascular system has the same organs as ours. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals. Pneumonia - Inflammation in any part of the lung tissue. Type I pneumocytes are flat cells that cover most of the alveolar surface and gases can easily pass through their cytoplasm. This system is made up of the cilia of the respiratory epithelium cells, along with secretions from the goblet cells and the seromucous glands that are below the respiratory mucosa. 1700 South Main StreetGoshen, Indiana 46526 The pig stomach is two to three times larger and the cardiac mucosa occupies a greater portion of the stomach compared to the human stomach. The former defend the alveolar lumen by phagocytizing microorganisms and inhaled particles, while the latter are responsible for eliminating particles or pathogens that reach the lung via the bloodstream.
