The rumen, also known as a paunch, is the largest stomach compartment in ruminants. [1] The rumen and the reticulum make up the reticulorumen in ruminant animals. [2]The diverse microbial communities in the rumen allows it to serve as the primary site for microbial fermentation of ingested feed, which is often fiber-rich roughage typically indigestible by mammalian digestive systems.
A cannula in a cow's side. A cannulated cow or fistulated cow refers to a cow that has been surgically fitted with a cannula. [1] A cannula acts as a porthole-like device that allows access to the rumen of a cow, to perform research and analysis of the digestive system and to allow veterinarians to transplant rumen contents from one cow to another.
The end-exhalatory lung volume is now well below the resting mid-position and contains far less air than the resting "functional residual capacity". However, in a normal mammal, the lungs cannot be emptied completely. In an adult human, there is always still at least 1 liter of residual air left in the lungs after maximum exhalation. [6]
The lungs stretch from close to the backbone in the rib cage to the front of the chest and downwards from the lower part of the trachea to the diaphragm. [1] The left lung shares space with the heart, and has an indentation in its border called the cardiac notch of the left lung to accommodate this.
The reticulum is adjacent to the diaphragm, lungs, abomasum, rumen and liver. The heights of the reticular crests and depth of the structures vary across ruminant animal species. [3] Grazing ruminants have higher crests than browsers. However, general reticulum size is fairly constant across ruminants of differing body size and feeding type.
The rumen is the major site of methane production in ruminants. [41] Methane is a strong greenhouse gas with a global warming potential of 86 compared to CO 2 over a 20-year period. [42] [43] As a by-product of consuming cellulose, cattle belch out methane, there-by returning that carbon sequestered by plants back into the atmosphere.
The lungs are the largest organs in the lower respiratory tract. The lungs are suspended within the pleural cavity of the thorax. The pleurae are two thin membranes, one cell layer thick, which surround the lungs. The inner (visceral pleura) covers the lungs and the outer (parietal pleura) lines the inner surface of the chest wall. This ...
The 'leaflets' of the omasum. The omasum can be found on the right side of the cranial portion of the rumen. [3] It receives food from the reticulum through the reticulo-omasal orifice [3] and provides food to the abomasum through the omaso-abomasal orifice. [4]
