How do fats affect the gastrointestinal tract and digestion?
In the stomach fat is separated from other food substances. In the small intestines bile emulsifies fats while enzymes digest them. The intestinal cells absorb the fats. Long-chain fatty acids form a large lipoprotein structure called a chylomicron that transports fats through the lymph system.
Which of the following is a feature of the muscular actions of digestion quizlet?
Which of the following is a feature of the muscular actions of digestion? Segmentation in the intestines allows periodic squeezing along its length, resulting in momentary reversal of the movement of intestinal contents –REMEMBER THE DEFINITION OF PERISTALSIS AKA THE CONTRACTIONS IN YOUR INTESTINES..
What does the GI tract secrete?
GI secretions include enzymes and fluids which aid in the liberation of nutrients from food, as well as mucus which facilitates transport of food down the alimentary tract.
Which of the following is a feature of peristalsis?
Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.
How is blood routed through the digestive system quizlet?
How is blood routed through the digestive system? Water- soluble nutrients and small products of fat digestion enter the bloodstream directly; large fats and fat- soluble nutrients are absorbed first into the lymph.
What are the physiological conditions of the GI tract?
The major processes that occur in the GI tract are: motility, secretion, regulation, digestion and circulation. The proper function and coordination of these processes are vital for maintaining good health by providing for the effective digestion and uptake of nutrients.
Which is a characteristic of the GI tract?
Which of the following is a characteristic of the appendix? it ferments fiber, it stores lymph cells, it slows down peristalsis, it stores preformed stools Which of the following is a feature of peristalsis? What is meant by the term “motility” in reference to the GI tract?
What are the characteristics of the digestive process?
All of the following are characteristics of the process of digestion except: salivary glands contribute little to digestion, the pyloric sphincter opens about 3 times a minute, saliva contains enzymes that digest sugars fats and proteins, the liver and pancreas contribute essential fluids to the digestive process
What are the features of stomach acid except?
All of the following are features of stomach acid except: ingestion of decaf/regular coffee, destroys most bacteria from ingestion, its potentially destructive action of stomach cells is prevented by the presence of bile. its potentially destructive action of the stomach cells is prevented by the presence of bile.
Which is GI tract organ has the strongest muscles?
Among the GI tract organs, which has the strongest muscles? Which of the following is a feature of the muscular actions of digestion?
What is the Order of the GI tract?
The GI tract can be divided into an upper and a lower tract. The upper GI tract consists of the mouth, pharynx, esophagus, and stomach. The lower GI tract is made up of the intestines and the anus. The upper GI tract consists of the mouth, pharynx, esophagus, and stomach.
Where are fats digested in the body?
Fats are digested in the small intestine. The secretion of liver called bile, breaks down the large globules of fat into smaller globules. This is called emulsification of fats.
Where is most fat digested?
The majority of fat digestion happens once it reaches the small intestine. This is also where the majority of nutrients are absorbed. Your pancreas produces enzymes that break down fats, carbohydrates, and proteins.
Are fats absorbed directly into the bloodstream?
Short- and medium-fatty chains can be absorbed directly into the bloodstream via the portal system from the intestinal microvillus because they are water-soluble. Cholesterol absorption is hindered by foods high in fiber. When energy supplies are low the body utilizes its stored fat reserves for energy.
