The proventriculus is a standard part of avian anatomy, and is a rod shaped organ, located between the esophagus and the gizzard of most birds. [2] It is generally a glandular part of the stomach that may store and/or commence digestion of food before it progresses to the gizzard. [3]
The ruminant digestive system. The omasum, also known as the green, [1] the fardel, [1] the manyplies [1] and the psalterium, [1] is the third compartment of the stomach in ruminants. The omasum comes after the rumen and reticulum and before the abomasum. Different ruminants have different omasum structures and function based on the food that ...
Digestive system of ruminants [ edit ] Hofmann and Stewart divided ruminants into three major categories based on their feed type and feeding habits: concentrate selectors, intermediate types, and grass/roughage eaters, with the assumption that feeding habits in ruminants cause morphological differences in their digestive systems, including ...
Bird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding flight.Birds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly.
The ruminant digestive system. The abomasum, also known as the maw, [1] rennet-bag, [1] or reed tripe, [1] is the fourth and final stomach compartment in ruminants. It secretes rennet, which is used in cheese creation. The word abomasum (ab-"away from" + omasum "intestine of an ox") is from Neo-Latin and it was first used in English in 1706.
Gizzard of a chicken. The gizzard, also referred to as the ventriculus, gastric mill, and gigerium, is an organ found in the digestive tract of some animals, including archosaurs (birds and other dinosaurs, crocodiles, alligators, pterosaurs), earthworms, some gastropods, some fish, and some crustaceans.
In a bird's digestive system, the crop is an expanded, muscular pouch near the gullet or throat. It is a part of the digestive tract, essentially an enlarged part of the esophagus. As with most other organisms that have a crop, it is used to temporarily store food. Not all bird species have one.
Foregut fermentation is a form of digestion that occurs in the foregut of some animals such as the hamster rat, langur monkey, and the hippopotamus. [1] It has evolved independently in several groups of mammals, and also in the hoatzin, a bird species. Foregut fermentation is employed by ruminants and pseudoruminants, some rodents and some ...
