muscularis
It contractS and relaxes to churn the food and mix it with the bile and other digestive enzymes.
The third layer, the obliquely oriented layer, of smooth muscle in its muscularis externa allows the stomach to churn, mix, and pummel the food, physically reducing it into smaller pieces.
It allows the stomach to move food along the tract, but also to churn, mix, and pummel food, physically breaking down food into smaller fragments
Chyme
The stomach and it's acids churn the food when you eat.
The muscle tissue is modified to form layers that are perpendicular to each other. This allows the stomach to churn (peristalsis) in different directions so as to hasten the physical and chemical breakdown of foods.
The stomach.
The stomach.
Yes, so it can digest and churn food around.
The peristaltic wave moves food along the digestive tract by contracting and relaxing the smooth muscles in the walls of the organs. It also helps to mix and churn the food with digestive enzymes and fluids for optimal digestion.
The oesophagus contracts to push/move food along through it. This motion of contraction to move food along is calledperistalsis. The tongue just helps with moving the bolus (roundish ball of chewed food mixed with saliva) from the mouth cavity and into the oesophagus.
The stomach contains a third oblique layer of smooth muscle fibers, in addition to the inner circular and outer longitudinal layers. This unique arrangement allows the stomach to effectively churn and mix food with gastric juices, facilitating digestion. The oblique layer enhances the stomach's ability to perform complex movements necessary for breaking down food.
