What type of epithelium lines the intestines where it secretes digestive juices and absorbs nutrients?
The stomach and intestines have a thin simple columnar epithelial layer for secretion and absorption.
Which organs allows nutrients to be absorbed?
The small intestine absorbs most of the nutrients in your food, and your circulatory system passes them on to other parts of your body to store or use. Special cells help absorbed nutrients cross the intestinal lining into your bloodstream.
Which 3 nutrients were absorbed by capillaries in the small intestine?
Examples. Examples of nutrients absorbed by the small intestine include carbohydrates, lipids, proteins, iron, vitamins, and water.
Where is lamina propria?
The lamina propria is a thin layer of connective tissue that forms part of the moist linings known as mucous membranes or mucosa, which line various tubes in the body, such as the respiratory tract, the gastrointestinal tract, and the urogenital tract.
Which of the following produces Pepsinogen?
stomach
The stomach produces several substances which aid in the digestion and absorption of nutrients. These substances include pepsinogen, hydrochloric acid, and intrinsic factor. Mucus is also secreted to coat the epithelium of the stomach.
What do the blood capillaries in the lamina propria absorb?
The lamina propria supports the epithelial cells and makes up the core of the villus. Present in this layer are blood vessels, immune cells, and a lymphatic vessel, or lacteal, that is important for fat absorption.
Which of the following is produced in the stomach and contributes directly to the absorption of B12?
The intrinsic factor (IF) is a glycoprotein produced by the parietal cells (oxyntic cells) located at the gastric body and fundus. Intrinsic factor plays a crucial role in the transportation and absorption of the vital micronutrient vitamin B12 (cobalamin, Cbl) by the terminal ileum.
Which nutrients were absorbed by capillaries in the?
The blood capillaries absorb most nutrients, but the fats and fat-soluble vitamins are absorbed by the lacteals.
Where should the capillaries be placed to maximize the absorption of nutrients from food?
where should the lymphatic vessels be placed to maximize the absorption of nutrients from food? the upper section of the small intestine.
Where do the capillaries go in the digestive system gizmo?
Capillaries: Capillaries should be placed on the small and large intestines. Lymphatic vessels: Lymphatic vessels should be placed on the small intestine only. 6. Challenge: Using a total of only five organs, design a digestive system that can absorb the maximum number of Calories from the apple.
