Coeliac disease is an autoimmune disease where the immune system reacts abnormally to gluten. For people with coeliac disease, even small amounts of gluten can damage the lining of the small intestine (bowel), which prevents the proper absorption of food nutrients.
Which of the following digestive complaints are commonly caused by bacterial infections?
Common symptoms of bacterial digestive infections
Abdominal bloating. Abdominal pain. Diarrhea that may be bloody. Flatulence.
Which statement best describes the breakdown of food in the digestive system?
Which statement best describes the breakdown of food in the digestive system? Carbohydrate digestion starts in the stomach and protein digestion starts in the stomach.
Where does mechanical digestion begin?
The large pieces of food that are ingested have to be broken into smaller particles that can be acted upon by various enzymes. This is mechanical digestion, which begins in the mouth with chewing or mastication and continues with churning and mixing actions in the stomach.
How do the digestive and excretory systems interact?
The excretory system removes waste from the body. remove waste from the blood. The digestive system breaks down the food you eat into nutrients that provide energy and building materials for cells. The digestive and excretory sytems work together to process the food that you eat.
What happens if digestion is not proper?
Not digesting food properly could lead to many health issues. You may experience constant belch, may suffer from flatulence and even face bloated stomach. The uneasiness could make the condition worse which may also lead to pain and discomfort in the stomach.
What happens when your digestive system is not working properly?
An unhealthy digestive system can impair your body’s ability to absorb nutrients, store fat and regulate blood sugar. Insulin resistance or the urge to overeat due to decreased nutrient absorption might cause weight gain. On the other hand, weight loss may be a result of bacterial overgrowth in the small intestine.
Which statement best describes changes to food during digestion?
Peptidase enzymes in the small intestine break food molecules into smaller molecules. Which statement best describes changes to food during digestion? The muscle contractions result in physical changes, while the action of the peptidase results in chemical changes.
Which structures of the digestive system aside from the small intestine release substances that break down food in the small intestine?
The pancreas and gland cells of the small intestine secrete digestive enzymes that chemically break down complex food molecules into simpler ones.
Which description best describes the digestive system?
The digestive system is the group of organs that break down food in order to absorb its nutrients. The nutrients in food are used by the body as fuel to keep all the body systems working. The leftover parts of food that cannot be broken down, digested, or absorbed are excreted as bowel movements (stool).
Where does digestion not occur in the digestive system?
It is a muscular tube that moves the incompletely processed food from mouth to stomach for additional absorption. Hence, Esophagus is one part of the digestive system where no digestion happens. Therefore, the correct answer for this question is B, i.e. Esophagus.
Which digestive processes occur first?
The mouth is the beginning of the digestive tract. In fact, digestion starts here as soon as you take the first bite of a meal. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.
What is the result of chemical digestion of carbohydrates?
During digestion, the bonds between glucose molecules are broken by salivary and pancreatic amylase, and result in progressively smaller chains of glucose. This process produces the simple sugars glucose and maltose (two glucose molecules) that can be absorbed by the small intestine.
What are 2 diseases associated with the digestive system?
Common digestive disorders include gastroesophageal reflux disease, cancer, irritable bowel syndrome, lactose intolerance and hiatal hernia. The most common symptoms of digestive disorders include bleeding, bloating, constipation, diarrhea, heartburn, pain, nausea and vomiting.
What systems interact with the digestive system?
Digesting food requires teamwork between the digestive system and several other organ systems, including the nervous, cardiovascular, and muscular systems. When you eat a meal, the organs of the digestive system need more blood to perform their digestive functions.
