Why is digestion important?
Most absorption takes place in the walls of the small intestine, which are densely folded to maximize the surface area in contact with digested food. The celiac artery is the first major branch from the abdominal aorta , and is the only major artery that nourishes the digestive organs. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement. Digestion is helped by the chewing of food carried out by the muscles of mastication , by the teeth , and also by the contractions of peristalsis , and segmentation. Water is absorbed here and the remaining waste matter is stored prior to defecation.
Digestive System Physiology
The analysis revealed that some statistically significant weight loss occurred, but the magnitude of the effect is small and the clinical relevance is uncertain. They also found that gastrointestinal adverse events were twice as likely in the hydroxycitric acid group as in the placebo group.
When you are considering the potential benefits of products look for meta-analysis studies that take in all the sound research available. One-off studies that get a significant result are not evidence of anything. Only when an effect is repeated in many studies by many scientists should you believe.
