What parts of the digestive system are mechanical and chemical?
Proper digestion requires both mechanical and chemical digestion and occurs in the oral cavity, stomach, and small intestine. Additionally, digestion requires the secretions from accessory digestive organs such as the pancreas, liver, and gallbladder.
Where is the mechanical digestive located?
mouth
Where does most mechanical and chemical digestion occur?
the stomach
What are the nervous and chemical mechanism that regulate the digestive system?
Neural Controls The walls of the alimentary canal contain a variety of sensors that help regulate digestive functions. These include mechanoreceptors, chemoreceptors, and osmoreceptors, which are capable of detecting mechanical, chemical, and osmotic stimuli, respectively.
What parts of the digestive system are mechanical?
Mechanical digestion begins in your mouth with chewing, then moves to churning in the stomach and segmentation in the small intestine. Peristalsis is also part of mechanical digestion.
What two places occur both mechanical and chemical digestion?
Food travels through the esophagus by peristalsis. A wave of muscular contractions pushes food through the esophagus from the pharynx to the stomach. Both mechanical and chemical digestion occur in the stomach. The squeezing and churning of stomach muscles mix and break food into smaller pieces.
