Where does fat digestion begins?
Fat digestion begins in the start of the small intestine, where emulsification by bile breaks it up physically and lipase acts on it to speed its conversion to fatty acids and glycerol.
What slows intestinal motility and causes the pyloric sphincter to contract?
the pyloric sphincter regulates the speed at which the chyme (mixture of food from stomach) can enter into the small intestine to be digested. The pyloric sphincter opens and closes according to the acidity of the chyme.
What is the general function of enzymes in the human body?
they speed up chemical reactions
Why does a small increase in speed produce a large increase in kinetic energy?
Kinetic energy is proportional to (depends upon) the square of the speed (velocity). If the speed is doubled then the KE is increased by a factor of 4 (2 squared).
What enzyme in your mouth that starts the starts down the break down of starches?
Salivary Amylase (also known as Ptyalin) is found in saliva. It breaks down starch into dextrose and maltose (simple sugars). The speed of the process is enhanced by gastric acids. basically the enzyme Amylase break down starch in to smaller molecules so the small intestine can absorb it.
Why does the vast majority of fat digestion occur in the small intestine?
there arefour points: 1.presence of villi gives large surface area for absorption 2.villi consist of extensive network of blood vessels which allows max assimilation and absorption 3.the length of the small intestine is so long and the digestion is a slow process, thus by the time the food or chyme reaches the end of the small intestine, its completely absorbed 4.intestinal juices present in small intestine speed up the absorption -> write this in exam and you will pakka get full ;D
What is the difference between absorption of the small intestines and large intestines?
small intestines disolve faster due to the rapid speed of the spleen vesel. While the larger intestine disolves slower under the organ range.
Where is the absorbed in the digestive system?
Approximately 80% of alcohol is absorbed in the upper portion of the small intestine. The rate of absorption depends upon things like:the concentration of alcohol in the beverage - the greater the concentration, the faster the absorptionthe type of drink - Carbonated Beverages tend to speed up the absorption of alcoholwhether the stomach is full or empty - food slows down alcohol absorption.
How are 3 structures of the villus related to the role of the villus in absorption?
Villi is numerous finger-like projections on the walls of small intestine. It helps in the absorption of dissolved food substances from intestine to other parts of the body. Villi increase surface area so as to speed up rate of diffusion. There are also microvilli found on vills to further increase surface area. The villi and intestinal walls are richly supplied with blood vessels and lymphatic vessels to carry away absorbed food substances.also, blood is red but villa may make it blue if you have villa syndrume. you may have this if you can see veins in your arm! hope that helps sweetie......

Enzyme in small intestine?
There are enzymes in the small intestine to speed up break down of nutrients (proteins, lipids, nucleic acids, and carbohydrates) that pass through the small intestine. The small intestine is where most of the chemical digestion that your food undergoes occurs, and where most of the nutrients your body needs are drawn from. The enzymes break down polymeric macromolecules, so that your body can easily absorb them. Simply put, starches and large sugars are broken down into simple sugars, such as glucose, the most simple sugar, proteins into amino acids, and lipids(fats) into fatty acids and glycerol.
Does water tend to speed up the absorption of alcohol?
No but Carbonated Beverages do.
What help to speed up the absorption of alcohol?
Drink Lot's of water
Does alcohol enter the bloodstream immediately after digestion?
Approximately 80% of alcohol is absorbed in the upper portion of the small intestine. The rate of absorption depends upon things like:the concentration of alcohol in the beverage - the greater the concentration, the faster the absorptionthe type of drink - carbonated beverages tend to speed up the absorption of alcoholwhether the stomach is full or empty - food slows down alcohol absorption.
Why is the inner mitochondrial membrne folded?
The mitochondrial membrane's cristae are similar in size to villa lining the intestine and are there for much of the same purpose, to increase surface area for absorption.
What are the adaptations of the small intestine?
In this case, I am assuming that you are asking for the diffusion of digested food substances, namely fats, sugars (glucose)and amino acids. Firstly, the surface area of the small intestine is increased: 1. the inner walls of the small intestines have numerous folds 2. the inner walls of the small intestine are also lined up with numerous minute finger-like projections called villi. These villi further increase the surface area for absorption. 3. The epithelial cells of the villi, in turn, have numerous microvilli to further increase the surface area Secondly, the small intestine is super long, about seven metres in an adult. This provides sufficient time for the absorption of digested food substances. Thirdly, the aforementioned villi have thin walls or membranes (epithelium is only one cell thick) Fourthly, the intestinal wall and the villi have many capillaries to carry away the absorbed food substances. In each villus is a lacteal or lymphatic capillary surrounded by blood capillaries. The lymphatic capillaries of the villi transport fats while the blood capillaries transport amino acids and sugars away from the intestine. Glucose and amino acids are thus absorbed by diffusion into the blood capillaries of the villi. Do note that the rate of diffusion is affected by the speed of blood flow. Slower blood flow will impair diffusion due to gentler concentration gradient. Hope this helps.

In which organ is most food digested and absorbed during digestion?
I will have to say the digestive system break down the most food because it contains enzymes which breaks down substrates and speed up chemical reactions and allows it to flow through your blood stream, amalyst, catalyst, enzyme pepsin, and others. The stomach
