DIGESTIVE PHYSIOLOGY Meaning and
Definition
-
Digestive physiology is a branch of physiology that pertains to the study of the function and processes involved in the digestion of food within the human body. It encompasses the intricate mechanisms and interactions that take place from the moment food is ingested to its conversion into essential nutrients and elimination of waste substances.
The process of digestion involves various physiological functions and organs, such as the mouth, salivary glands, esophagus, stomach, small intestine, large intestine, liver, pancreas, and gallbladder, working together to break down food into its basic components and absorb the necessary nutrients. Digestive physiology explores the muscular contractions, chemical reactions, and enzymatic activities that occur during digestion.
This field of study delves into understanding the mechanisms behind the ingestion, mastication, swallowing, digestion, absorption, and excretion of food. It aims to comprehend the role of different enzymes, hormones, electrolytes, and sensory receptors involved in the regulation of appetite, satiety, and energy metabolism.
Through experimental research and observations, digestive physiology seeks to unravel the intricacies of nutrient absorption, utilization, and storage. This knowledge is crucial in understanding the detection and treatment of various digestive disorders, such as ulcers, irritable bowel syndrome (IBS), Crohn's disease, and gastroesophageal reflux disease (GERD). Moreover, it provides insight into the impact of diet and lifestyle choices on digestive health and overall well-being.

Etymology of DIGESTIVE PHYSIOLOGY
The word "digestive" comes from the Latin word "digestio", which means "a digesting, a digestion, the process of digestion". It is derived from the verb "digestus", the past participle of "digero", which means "to separate, dissolve, digest".
The word "physiology" comes from the Latin words "physiologia" and "physiologicus", which mean "knowledge of natural principles, natural science, study of nature". It is derived from the Greek word "physis", meaning "nature", and "logia", meaning "study of".
Therefore, "digestive physiology" refers to the study of the natural processes and mechanisms involved in digestion.
