What is the site of final digestion?
In a human's digestive tract, the final site of digestion is the small intestine.
What function does digestive tract perform?
The digestive system breaks down ingested food into usable nutrients. It also provides a site where these nutrients are absorbed into the circulatory system for transport to all body cells. Lastly, it eliminates solid waste -- undigested food.
What does a 'fantastic voyage' through the lumen of the digestive tract mean?
It may mean a site but most like a book by that name. You ride along with a meal some one ate.
Why mouth important in digestive system?
The mouth allows you to ingest food, or take food into your body. In addition, the mouth is the site of the first mechanical and chemical digestion in the GI tract.
What is the stomachs job for the digestive system?
The stomach plays a crucial role in the digestive system by breaking down food into a semi-liquid form called chyme. It achieves this through the secretion of gastric juices, which contain hydrochloric acid and digestive enzymes that help to further digest proteins and kill harmful bacteria. Additionally, the stomach serves as a temporary storage site for food, regulating its release into the small intestine for further digestion and nutrient absorption.
What have most chemical digestion and absorption?
The small intestine is the site of most chemical digestion and absorption in the digestive tract. During absorption, nutrients enter the bloodstream, and the circulatory system can then transport these nutrients to all body cells.
Which digestive enzymes are action at site different from the site where they are produced?
amylase
Is the hypothalamic-hypophyseal tract the site of prolactin synthesis?
NO
What process does water enter the blood?
Water that you drink, like all nutrients, enters the blood in the digestive tract. Water is different for example from proteins and fats in that it gets absorbed throughout the digestive tract and not only in a particular part such as the stomach or a part of the intestines. The major site of water readsorption from the intestines however is the large intestine (colon). Here, the removal of water and uptake into the blood contributes towards drying and concentrating the stool.
Why doesn't the small intestine contain the acid chyme?
The duodenum is the main site for digestion in the small intestine. Here, more enzymes are added to the chyme, some of which come from the intestinal wall and others from the pancreas. The pancreas is one of the major glands of the body, and has two functions: releasing digestive enzymes into the gut, and releasing hormones into the blood. Pancreatic juice also contains sodium bicarbonate, which neutralizes the acid chyme arriving in the duodenum, and provides an alkaline environment for optimum functioning of pancreatic and intestinal enzymes. These enzymes include proteases to continue protein digestion, amylase for carbohydrate digestion, and lipase for fat digestion. Enzymes in the intestinal juice generally start off the later stages of digestion.
What is the main cause of GI bleeding?
Bleeding in the digestive tract is a symptom of a disease rather than a disease itself. A number of different conditions can cause bleeding. Most causes of bleeding are related to conditions that can be cured or controlled, such as ulcers or hemorrhoids. Some causes of bleeding may be life threatening.Locating the source of bleeding is important. Different conditions cause bleeding in the upper digestive tract and the lower digestive tract. The upper digestive tract includes the esophagus, stomach, and upper portion of the small intestine, also called the duodenum. The lower digestive tract includes the lower portion of the small intestine; large intestine, which includes the colon and rectum; and anus.The signs of bleeding in the digestive tract depend on the site and severity of bleeding.Signs of bleeding in the upper digestive tract includebright red blood in vomitvomit that looks like coffee groundsblack or tarry stooldark blood mixed with stoolstool mixed or coated with bright red bloodSigns of bleeding in the lower digestive tract includeblack or tarry stooldark blood mixed with stoolstool mixed or coated with bright red bloodSudden, severe bleeding is called acute bleeding. If acute bleeding occurs, symptoms may includeweaknessdizziness or faintnessshortness of breathcrampy abdominal paindiarrheapalenessA person with acute bleeding may go into shock, experiencing a rapid pulse, a drop in blood pressure, and difficulty producing urine.Light bleeding that continues for a long time or starts and stops is called chronic bleeding. If bleeding is chronic, a person may notice that fatigue, lethargy, and shortness of breath develop over time. Chronic blood loss can also lead to anemia, a condition in which the blood's iron-rich substance, hemoglobin, is diminished.A person may not notice a small amount of bleeding in the digestive tract. This type of bleeding is called occult bleeding. Simple tests can detect occult blood in the stool.
What is the site of the filtrate formation?
upper respiratory tract
