How does swallowing help in digesting food?
Swallowing helps to pass something from mouth to our pharynx to insert some nutrients in our body.
The liver, pancreas, and salivary glands are all part the digestive system, but food doesn't pass through them. All three produce enzymes and chemicals that break up nutrients. The liver produces bile, the salivary glands produce saliva, and the pancreas a mix of enzymes. The liver and pancreas work with other systems as well.
How much water does a human mouth hold?
Mine holds 1/2 cup (4 floz)...I feel weird for saying this.
About 4 ounces is average i think.
What is a common passage for both digestive and the respiratory systems?
The pharynx (and the glottis flap) in the throat are used by both systems, i.e. to swallow food and to breathe.
What digests excess or worn out cell part food particles and invading viruses or bacteria?
Lysosomes. These organelles contain digestive enzymes within itself and can digest pathogens and worn out cell parts. It is also known as a suicide sack because when given the orders, it can burst and destroy the cell from inside out in times of mutations.
Where does the most commercial farming take place in?
Most commercial farming takes place in Europe and North America with scattered commercial farming taking place in sub-Saharan Africa and Australia. This is mainly so because the right environmental conditions apply in these areas and the farmers have sufficient capital to undertake in commercial farming.
Name two lower gastrointestinal system procedures that involve and endoscope?
Colonoscopy - The direct visual examination of the inner surface of the entire colon from the rectum to the cecum.
Sigmoidoscopy - The endoscopic examination of the interior of the rectum, sigmoid colon, and possible a portion of the descending colon.
If food and drink swallowed and goes down wrong pipe can you get phnemonia?
Yes you can. When you swallow anything other than water into your lungs you will usually cough nonstop and it will develop a mucus around the object which leads to the illness. While this may not be quite the right explanation in medical terms exactly, to answer the question...yes.
What is the big idea of particles?
Particles are microscopic and explain the properties of liquids, solids, and gases. The strength of the bonds between particles is different in each state.
In digestion, the chunks of foods we eat must be broken down into particles to be used by the body.
How does the tissue in the stomach enable the stomach to function?
The stomach is lined with specialized tissues that facilitate its functions, primarily through a mucosal layer containing gastric glands. These glands secrete digestive enzymes, hydrochloric acid, and mucus, creating an acidic environment essential for breaking down food and killing pathogens. The muscular layers of the stomach wall allow for rhythmic contractions, helping to churn and mix the food with digestive juices. This coordinated action ensures efficient digestion and the gradual release of partially digested food into the small intestine.

Why does eating a salad cause excessive gas?
The only salads that give me gas are those that are prewashed and sold in bags. I have no problem with fresh unbagged salad greens that I wash myself. Most restaurants now are serving prewashed treated greens and these make me belch and frequently nauseous as well. They are washed in chlorine and a variety of gases may be added to the bag to prolong "freshness". Stay away from these and you should be fine.
What acid is produced when a fat is digested?
Fats are broken down into Free Fatty Acids and Glycerol
What is the function of the salvatary glands?
The salivary glands keep the mouth wet so your cheeks, tongue, and teeth do not stick to one another. The salivary glands also begin the digestion of starchy foods by breaking them down into slightly simpler chemical forms.
What 3 parts of a cell takes care of ingestion digestion and excretion?
cell membrane, cytoplasm and vacuoles
What organel digests foreign material?
wo cells in the same organism differ only in the number of chloroplasts they contain. The first cell has multiple chloroplasts, and the second cell has very few. What would most likely characterize these cells?
Why should we chew our food well?
It is important to chew your food thoroughly before swallowing it because digestion begins in the mouth. One of the enzymes that your saliva contains is called alpha amylase. This enzyme is responsible for breaking down the starches that you eat into smaller molecules that the cells in your body can use for energy. When your food is not chewed properly, the alpha amylase in your saliva does not have the opportunity to break down these starches, leaving body cells starved.
What does the tongue push food into after it has been chewed and lubricated?
After food has been chewed and lubricated, the tongue pushes it into the pharynx, which is the part of the throat behind the mouth. This action helps facilitate swallowing, allowing the food to move from the oral cavity into the esophagus and eventually to the stomach for digestion.
What is the upper part of tje intestine in frogs that aids the digestive fluid?
The upper part of the intestine in frogs is called the duodenum. It plays a crucial role in digestion by receiving digestive fluids from the pancreas and bile from the liver, which help to break down food. This process allows for the efficient absorption of nutrients as the food continues its journey through the intestines.
