The mouth and the stomach.
The most important end product of digestion is the separation of nutrients, most of which are absorbed through the small intestine and distributed throughout the body cells by the circulatory system.
Starts carbohydrate digestion
The digestive system begins at the mouth where teeth are used to break and grind up food and carbohydrate digestive enzymes begin the process of digesting carbohydrate. Jerry Hart, MS. College Instructor in Nutrition
The parasympathetic division is known as the resting and digesting division of the autonomic nervous system. This division is responsible for calming the body, conserving energy, and promoting digestion and elimination of waste.
cellulose. humans do not possess the enzymes necessary for its digestion.
No, the parasympathetic nervous system is often referred to as the resting and digesting system, as it controls functions like digestion, relaxation, and energy conservation. The sympathetic nervous system is responsible for the "fight or flight" response, activating the body in times of stress or danger.
Products of carbohydrate digestion and protien digestion move through brush border cells, diffuse through the interstitial fluid inside the villus, then enter a capillary. Products of fat digestion also cross the brush border cell and interstitial fluid, but they enter lymph vessels which eventually carry them to the blood.
In the small intestine
Fibre helps prevent consitpation Fibre has no fat unless it is not used up to provide energy Fibre aids the digestion of food by passing through the body unaffected Fibre pushes food down the foodpipe/oesophagus (peristalsis) and aids digestion this way
The stomach digests the proteins in a meal. When it is finished digesting those proteins, the food leaves the stomach to be digested more and absorbed in the small intestine.
The renal system eliminates some of the waste products produced by digestion; in particular proteins.
The resting and digesting division of the autonomic nervous system is the parasympathetic division. Resting and digesting is also referred to as feed and breed.
