What is the first place where starch is digested?
digestion of starch starts when food enters the mouth. our mouth has saliva which contain
enzyme called ptyalin (salivary amylase) which converts starch into peptones & peptides.
Does the human body have a poop muscle?
Yes it does. The internal and external anal sphincters along with the puborectalis muscle allow the feces to be passed by pulling the anus up over the exiting feces in shortening and contracting actions.
Is Digestion of food -endothermic or exothermic reaction?
digestion of food release energy, so it's exothermic reaction
The concentration of acid is lower in vegetables than it is in fruits. Tomatoes are the vegetables with the highest concentration of acid with a pH of 4.0 to 4.6. Most vegetables fall within the pH range of 5 to 5.6 and are considered low acid. Potatoes, peas and corn are least acidic with a pH of 6.1 to 6.3.
Where does the digestive system give off energy?
The digestive system breaks food down into the three main components of protiens, fats and carbohydrates. Carbohydrates are the primary energy source of the human body. Metabolism takes over after the digestive system is through helping turn your food into you. But carbs break down into simple suger called glucose. Glucose is the energy of the human body. With the aid of insulin glucose enters the cells and provides chemical energy for all the movement of your body. It also provides for alertness, clear thinking, and cell reproduction.
Does the digestion process begin with the large intestine mouth small intestine or stomach?
The digestion process begins in the mouth.
What is the organ responsible for food and water absorption?
The small intestine is where most nutrients are absorbed, but the large intestine is responsible for most water absorption
What keeps the digestive system healthy?
That is a good patai i will say that healthy eating is good such as eating 5 fruits a day and also eating vitamins and minarals
Does the mouth belong to the digestive system or respiratory?
Your mouth is part of both the digestive and the respiratory system.
It belongs to the digestive system, because it adds saliva, which helps break down the starches before further digestion in the stomach. Ptyalin is one of the important chemicals. Additionally, of course the mastication definitely aids the digestive process.
And it belongs to the respiratory system for under exercise, it becomes the main entry way for air. But probably without the moisturizing qualities added by the passage through the nose.
Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body. Waste products of digestion pass through the large intestine and out of the body as a solid matter called stool.

How does the circulatory system delivers oxygen and glucose to tissues?
blood provides oxygen to the body
I think that perhaps you mean the polypeptides, which is a polymer of many amino acids. The protein is broken down into polypeptides, which are in turn broken down into amino acids - the building blocks of pretty much all of the human body.
What does the pepsin have to do with the digestion system?
When you eat, your body needs to digest the food and turn it into a form that the body can use for nutritional purposes. Digestion refers to the chemical breakdown of large food molecules into smaller molecules that can then be used by cells. This process occurs when certain enzymes are mixed with the food. One of those enzymes is pepsinogen, which is converted to pepsin; pepsin is important because it digests proteins.
What Is the joint in the middle of arm called?
it's called an elbow.
The joint in the middle of the arm is the elbow.
elbow
The joint that is used when bending the elbow is aSynovial Joint.
A considerable amount of movement is permitted a all synovial joints and types are subdivided according to the movements.
The elbow would be specifically considered a Hinge Joint: This type permits movement in one plane only. The movements are flexion and extension. Other examples of hinge joints are knee, ankle interphalangeal joints of the fingers and toes.
* so its a synovial joint...but a Hinge joint type...other types are ball and socket eg: hip etc.
Hope it helps :)
What effect does alcohol being absorbed in the stomach have?
It increases blood alcohol concentration (BAC).
What part of the digestive system produces enzymes?
Enzymes are produced in various regions of our digestive system. Starch is digested by amylase produced by our salivary glands; protein is broken down by pepsin, manufactured in the stomach. In the upper part of the small intestine - the duodenum - all main nutrient molecules are broken down by enzymes made in our pancreas and by the small intestine itself.
Stores food 3 to 4 hours while digestion is occurring?
well actually no organ dose that.But i now food can atleast stay i your system for up to 1and 1/2 or maybe up to 2 hours. But after it digest through it goes out of your urinia and recuem
How does friction helps in chewing the food?
Chewing food helps digestion because it breaks down foods so the stomach doesn't have to do so much work. Saliva helps it to be liquefied and adds enzymes that begin digestion. If we just swallow chunks even without chewing, the food will still be digested but the process would take longer.
