Which of the following is an accessory organ of digestion?
The salivary glands, liver, gallbladder, and pancreas are not part of the digestive tract, but they have a role in digestive activities and are considered accessory organs..
Which is not an accessory organ of digestion?
kidneysThe kidneys are not accessory organs of digestion.
Which macronutrient has the highest satiety value quizlet?
Which macronutrient has the highest satiety value? Foods containing carbohydrates have the highest satiety value.
Which area of the brain is primarily in control of eating?
hypothalamusThere are two places in the hypothalamus, part of the brain, that controls hunger and eating. The Ventromedial Nuclei gives a signal when to stop eating, and the Lateral hypothalamus gives a signal to start eating (e.g.,Coon 1995). We feel satiety at the brain level because of the function of the Ventromedial Nuclei.
How thick is the gut lining?
The stomach and colon have a two-layered mucus with an inner mucus layer that is 50-200 μm thick and firmly attached to the epithelium (Fig. 1). The outer mucus layer is easily removed and has a less defined outer border.

What are the main organ of the digestive system?
The alimentary tract of the digestive system is composed of the mouth, pharynx, esophagus, stomach, small and large intestines, rectum and anus. Associated with the alimentary tract are the following accessory organs: salivary glands, liver, gallbladder, and pancreas.
Which desire to eat is stimulated by the sight smell or thought of food?
AppetiteAppetite: The psychological desire to eat; a learned motivation and a positive sensation that accompanies the sight, smell, or thought of appealing foods.
How is all glucose in the small intestine absorbed through the epithelial lining?
Absorption of glucose entails transport from the intestinal lumen, across the epithelium and into blood. The transporter that carries glucose and galactose into the enterocyte is the sodium-dependent hexose transporter, known more formally as SGLUT-1.
When there is a sufficient buildup of cholesterol?
When there is a sufficient buildup of cholesterol, lipids, and scar tissue in the arterial wall to impair blood flow, atherosclerosis has developed. 2. Plaque is a thick, grainy deposit that consists of proteins, calcium, foam cells, platelets, and other substances.
What is the name of the sphincter that separates the stomach from the small intestine?
pyloric sphincterThe pyloric sphincter is a ring of smooth muscle that connects the stomach and small intestine. It opens and closes to control the passage of partially digested food and stomach juices from the pylorus to the duodenum.
Which macronutrients best promotes satiety?
It has been established that protein consistently exhibits the most pronounced effect on satiety of the three macronutrients. Carbohydrates and fat deliver the same amount of satiety per calorie when caloric density and palatability are matched.
Which type of cells form the lining of the small intestine?
The small intestine consists of four layers: mucosa, submucosa, muscle layer, and adventitia. The intestinal epithelium is lined with a single layer of polarized cells, among which the major types include enterocytes, goblet cells, Paneth cells, stem cells, and others.
Which part of the digestive system is the longest?
small intestineAlthough the small intestine is narrower than the large intestine, it is actually the longest section of your digestive tube, measuring about 22 feet (or seven meters) on average, or three-and-a-half times the length of your body.
Where does carbohydrate digestion begin?
Digestion begins in the mouth with salivary amylase released during the process of chewing. There is a positive feedback loop resulting in increased oral amylase secretion in people consuming diets high in carbohydrates. The amylase is synthesized in the serous cells of the salivary glands.
