MEDICAL PHYSIOLOGY

Detailed explanation-1: -During the fourth week of gestation, the duodenum begins to develop from two sources: the caudal part of the foregut and the cranial part of the midgut, where the junction lies just distal to the origin of the bile duct. The developing duodenum forms a C-shaped loop that initially projects ventrally.

Detailed explanation-2: -By about seven weeks of pregnancy, your baby’s oesophagus and stomach is forming (Moore et al 2019b). Around this time, the developing liver appears as a small outgrowth, and the pancreas also starts budding (Moore et al 2019b). These organs support your baby’s digestion.

Detailed explanation-3: -There are four stages in the digestive process: intake, chemical and mechanical degradation of food, nutrients’ absorption, and removal of indigestible food.

Detailed explanation-4: -Eat food. Break down the food into tiny pieces. Absorb nutrition into the body: move the small particles out of the digestive system and the rest of the body. Get rid of the waste, which is anything your body can’t use.
