There are diagnostic tools mostly involving the ingestion of barium sulphate to investigate disorders of the GI tract. [49] These are known as upper gastrointestinal series that enable imaging of the pharynx, larynx, oesophagus, stomach and small intestine [50] and lower gastrointestinal series for imaging of the colon.

Animals and other heterotrophs must eat in order to survive — carnivores eat other animals, herbivores eat plants, omnivores consume a mixture of both plant and ...
In most vertebrates, digestion is a multistage process in the digestive system, starting from ingestion of raw materials, most often other organisms. Ingestion usually involves some type of mechanical and chemical processing. Digestion is separated into four steps: Ingestion: placing food into the mouth (entry of food in the digestive system),
Ingestive behaviors encompass all eating and drinking behaviors. These actions are influenced by physiological regulatory mechanisms; these mechanisms exist to control and establish homeostasis within the human body. [1]
A new report by the Clean Label Project has found that protein powders may contain something other than muscle-building nutrients: lead and cadmium, both of which are toxic.. The national ...
