tract? Which cells are direct participants in formation, and how do they contribute to lesions in the G.I. tract wall? c. Zach’s stomach contributes to the formation of ulcers by the acids needed to breakdown food when they are excessive. Parietal cells (secrete HCI) and gastric glands (acetylcholine) are directly related to the formation of ulcers.
In between gulps of this nutritious meal, let us sneak in to his cavernous mouth. As we glide between his lips, which are pulled apart by his orbicularus oris, allow me to narrate our marvelous journey… through the digestive system. Digestion, a pertinent component of survival,
Identify three mechanical digestion activities. a. Chewing b. Mixing of food with saliva by tongue c. Churning food in the stomach and segmentation of the intestines 3. Name two feedback loops that regulate digestive system smooth muscle responsible for propulsive and mixing movements. Hormonal feedback loops and neural feedback loops. Neural Regulation of Mechanical Digestion 4.
As we continue to make our way to the heart, we merge with the right external iliac vein. This is also another name for the femoral vein, and is also considered a deep vein in the lower leg. Its main responsibility is taking deoxygenated blood from the legs back to the heart. It is located right behind the inguinal ligament in the lower abdomen. The inguinal ligament support the area between the abdomen and the thigh (Inguinal Ligament, n.d.).
In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food. The digestive tract also contains a layer of smooth muscle that helps break down food and move it along the tract. Two “solid” digestive organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes called ducts. The gallbladder stores the liver's digestive juices until they are needed in the intestine. Parts of the nervous and circulatory systems also play major roles in the digestive system.
