liver function tests, lipase, amylase, complete blood count (CBC), an abdominal X-ray, a HIDA scan (uses radioactive material) can measure gallbladder emptying while an ERCP test uses an endoscope to place dye in the ducts of the pancreas, gallbladder and liver, and. Magnetic resonance imaging (MRI) is sometimes used to detail the organ structures (liver, gallbladder, and pancreas).
Carbohydrates and protein break down to minute, absorbable structures, and are absorbed directly into the blood. 3. Two types of digestion occur in the mouth, mechanical and, to a lesser extent, chemical.
As the food goes into the oral cavity, it is mechanically digested by the teeth and chemically digested by saliva. Through the pharynx and oesophagus, the major chemical digestion occurs with enzyme secretions from different glands associated with the digestive tract. However, in some animals viz. crocodiles, ratite birds, and seals the mechanical breakdown of food items takes place in the stomach.
