These regulatory mechanisms, which stimulate digestive activity through mechanical and chemical activity, are controlled both extrinsically and intrinsically. The walls of the alimentary canal contain a variety of sensors that help regulate digestive functions.
What is Act 2 of the Pennsylvania Land recycling program?
Pennsylvania’s Land Recycling Program (Voluntary Cleanup Program) was established by a series of legislation enacted in 1995. This package (Acts 2, 3 and 4 of 1995) serves as the basis for what is more familiarly known as the Land Recycling Program or simply ‘Act 2.’
What are the two processes of digestion in the digestive system?
Processes of Digestion Digestion involves two processes – physical and chemical. During the physical process, the food is mixed and moved throughout the gastrointestinal tract. This process is also referred to as motility and the partially digested food is propelled by the wave-like action called peristalsis.
What are the benefits of the Act 2 program?
Financial assistance. The ACT 2 Land Recycling Program affords a developer of a contaminated site (brownfield) to choose any one or combination of cleanup standards that the remediation process can follow. This a dynamic approach that affords a greater degree of flexibility on site redevelopment.
How does the digestive system work?
The digestive system uses mechanical and chemical activities to break food down into absorbable substances during its journey through the digestive system. Table 23.2. 1 provides an overview of the basic functions of the digestive organs.
What phase of digestion controls the rate of gastric emptying?
Digestive Phases. This phase controls the rate of gastric emptying. In addition to gastrin emptying, when chyme enters the small intestine, it triggers other hormonal and neural events that coordinate the activities of the intestinal tract, pancreas, liver, and gallbladder.
How do the brain and the endocrine system control digestive processes?
The brain and the endocrine system control digestive processes. The brain controls the responses of hunger and satiety. The endocrine system controls the release of hormones and enzymes required for digestion of food in the digestive tract.
