Location of digestion and absorption of each macromolecule
Lipids are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. They include many natural oils, waxes, and steroids.
Carbohydrates is a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose. They contain hydrogen and oxygen in the same ratio as water
acid helps your body to break down, digest, and absorb nutrients such as protein. The hydrochloric acid found in the stomach facilitates digestion by disintegrating complex large food molecules into simpler molecules
Proteins are large biomolecules or macromolecules that are comprised of one or more long chains of amino acid residues.
Major organs of the digestive system
The major organs in the digestive system is the mouth, esophagus, stomach, small intestine, large intestine, and anus. Alos the liver, pancreas, and gallbladder are the solid organs of the digestive system as well.
Digestive enzymes
Amylase produced in the mouth. It helps break down large starch molecules into smaller sugar molecules.
Pepsin is an enzyme in the stomach, which breaks down proteins into polypeptides.
Trypsin is an enzyme that helps us digest protein. In the small intestine, trypsin breaks down proteins, continuing the process of digestion that began in the stomach.
Major functions of the digestive system
Digestion is the breakdown of food into small molecules, which are then absorbed into the body. The digestive system is divided into two and also has a tube that is the opening of the mouth and anus
absorption, the nutrients that come from food (such as proteins, fats, carbohydrates, vitamins, and minerals) pass through the wall of the small intestine and into the bloodstream. In this way nutrients can be distributed throughout the rest of the body.
Layers of the GI tract
mucous membrane layer of the stomach, which contains the glands and the gastric pits.
submucosa is the layer of dense, irregular connective tissue or loose connective tissue that supports the mucosa, as well as joins the mucosa to the bulk of underlying smooth muscle
The muscularis propria has 2 layers, the inner layer is circular, and the outer layer is longitudinal. These layers of smooth muscle are used for peristalsis to move food down through the gut.
serous membrane is a smooth tissue membrane of mesothelioma lining the contents and inside wall of body cavities, which secrete serous fluid to allow lubricated sliding movements between opposing surfaces.
Disorders of the digestive system
Gastroesophageal Reflux Disease (GERD) is a digestive disorder that occurs when acidic stomach juices, or food and fluids back up from the stomach into the esophagus
Diarrhea that lasts for more than 2-4 weeks is considered persistent or chronic. In an otherwise healthy person, chronic diarrhea can be a nuisance at best or become a serious health issue. For someone who has a weakened immune system, chronic diarrhea may represent a life-threatening illness.
