In crustaceans, specifically decapods such as the crayfish, the stomach is divided into two parts: the first, or anterior part is called the "gastric mill". The gastric mill is lined with chitinous teeth which grind up coarse food particles. The posterior part of the stomach acts as a filter to keep coarse particles from entering the digestive glands, where absorption takes place.
What else can I help you with?
What role does the gastric juices play digestion?
because,it breaks down and dissolve the nutrients in food..
What are gastric glands in frogs?
Gastric glands in frogs are structures located in the stomach lining that secrete digestive enzymes and hydrochloric acid to help break down food. These glands play a crucial role in the digestion process of frogs by aiding in the breakdown of food into nutrients that can be absorbed by the body.
What role do the parasympathetic division of the ans play in digestion?
The parasympathetic division of the autonomic nervous system stimulates digestion. It activates salivation, which functions in digestion as the beginning of breaking the food down. It also stimulates the gall bladder to release bile for digestion. Digestion in the small intestine is increased and gastric juice in the stomach is secreted.
What cell types make up gastric glands?
The main cell types that make up gastric glands are mucous neck cells, parietal cells, chief cells, and enteroendocrine cells. These cells work together to produce and secrete gastric juices in the stomach, which play a key role in digestion.
Is it true or false smooth muscles in the stomach are capable of mechanical digestion?
True. Smooth muscles in the stomach play a crucial role in mechanical digestion by contracting rhythmically to churn and mix the food with gastric juices. This process helps break down food into smaller particles and facilitates the enzymatic digestion that follows.
What acids are in gastric juices?
Hydrochloric acid is found in gastric juices. With the high acidic levels of hydrochloric acid, it creates a harsh environment and helps to kill off most of the bacteria living in the stomach.
What is a gastric caeca?
Gastric caeca are finger-like projections found in the digestive system of some animals, such as insects and crustaceans. They are located at the junction of the foregut and midgut and play a role in digestion and absorption of nutrients. Gastric caeca increase the surface area available for enzymatic activity and nutrient absorption, aiding in the efficient digestion of food.
What does the mouth and stomach do in mechanical digestion?
The mouth and stomach both play parts in the digestive system ;also in chemical and physical digestion.In chemical digestion, in the mouth the saliva is mixed with enzymes which breaks down food into bolus and in the stomach acids break down the food turning it into chyme.In Physical digestion in the mouth the teeth tears the food and the stomach churns it.
What role does the esophagus play in the digestion system?
it sends broken down food to the stomach for digestion
Where is endopeptidase made?
Endopeptidases are typically produced and secreted by various cells in the body, such as pancreatic acinar cells and gastric chief cells, as well as by certain microorganisms. These enzymes play a critical role in protein digestion by cleaving peptide bonds within the interior of protein molecules.
Does the appendix play a big role in the digestion system?
no
What role do lysosmes play in metabolism?
They involve in digestion.
