- The inside wall of the small intestine needs to be thin, with a really big surface area. This allows absorption to happen quickly and efficiently. If the small intestine had a thick wall and a small surface area, a lot of digested food might pass out of the body before it had a chance to be absorbed.

Small Intestine The small intestine is part of the gastrointestinal tract. Chyme from the stomach empties into the small intestine. The small intestine is responsible for most chemical digestion of food, and absorption of nutrients including proteins, lipids (fats) and carbohydrates.Once the small intestine has extracted the nutrients, the remaining waste proceeds to the large intestine before being expelled from the body.he digested food passes into the capillaries and lymphatic vessels in the wall of the intestine. Nutrients such as glucose and amino acids are absorbed into capillaries, while fats are absorbed into the lymph vessels. The ileum is the last section of the small intestine. It mainly absorbs vitamin B12 and bile salts.

What Does the Small Intestine Do? This surface area allows for greater exposure to the microvilli of the small intestine to absorb the maximum possible number of nutrients. Let’s examine how the body deals with carbohydrates, fats and proteins in the small intestine.

- Absorption into bloodstream. The inside wall of the small intestine is thin, with a large surface area. This allows absorption to happen quickly and efficiently. To get a big surface area, the inside wall of the small intestine is lined with tiny villi. These stick out and give a big surface area. They also contain blood capillaries to carry away the absorbed food molecules.

UNIT 1: BODY ESSENTIALS The small intestine secretes salts, acids, and enzymes, which continue the breakdown of proteins, fats, and carbohydrates. These digestive juices originate in the liver, gallbladder, and pancreas. Nutrients are absorbed into the blood-stream through small finger-like nodules on the wall of the small intestine called villi. Chemicals and other substances that cannot be digested by the body are passed into the large intestine.

Your small intestine and digestion The small intestine is the location in the body where the majority of the nutrients from ingested food are absorbed. Whereas the stomach is responsible for the churning and mechanical breakdown of food, the small intestine is very important for absorption.he ileum is preceded by the jejunum. This section of the small intestine is approximately 6 to 12 feet (3.5 meters) long. The ileum absorbs mainly vitamin B12, other water soluble vitamins, bile salts, and nutrients that were not absorbed in the jejunum.

- Ultrasound is absorbed in the body primarily. by bone, followed by nervous tissue, and last by. muscle tissue. This is believed to be due to the. high protein concentrations of these substances. Ultrasound easily penetrates the less homoge-. neous tissues such as water, blood plasma, and. whole blood.'.

What Happens to the Circulatory System During Exercise? The systemic circulatory system includes blood vessels that deliver oxygen and nutrient-rich blood to tissues throughout your body. Blood flows forcefully through your arteries and into capillaries, which release oxygen and nutrients into tissue cells. Waste products are collected by blood that flows into your veins.

- The drug in the intestine comes in contact with the intestinal mucosa (lining of the intestine) and is absorbed into the blood stream via the portal vein. This vein carries the recently absorbed drug to the liver and empties into the vena cava which carries the blood returning to the heart from the rest of the body.

How Does Body Absorb Carbohydrates, Fats and Proteins? In the small intestine, they are broken down into the simplest sugar molecules, which are then absorbed through the small intestine walls into the bloodstream and used by the body as fuel or sent for storage in the liver for use at a later time.

Which part of the digestive system is primarily responsible for absorbing nutrients? The small intestine. The wall of small intestine have small finger-like projections called villi which in turn have projections called microvilli. These structures increase …the surface area for absorption and hence absorb all the essential nutrients into the blood. 10 people found this useful.

- When you drink water, it is absorbed through the lining of the small and large intestines into your blood. This absorption occurs at a rate that depends largely on how much water you need at that time. Your body uses the concentration of certain elements to keep track of how much water is in the blood and tissues.

- 1 Absorption of Drugs Absorption is the transfer of a drug from its site of administration to the bloodstream. The rate and efficiency of absorption depend on the route of administration. For IV delivery, absorption is complete; that is, the total dose of drug reaches the systemic circulation.f the drug is rapidly metabolized by the liver, the amount of unchanged drug that gains access to the systemic circulation is decreased. 2. Solubility of the dru g: Very hydrophilic drugs are poorly absorbed because of their inability to cross the lipid-rich cell membranes.

Factors affecting Absorption of Drugs GI mobility must be optimal for absorption of oral drugs. It should be neither increased nor decreased which may affect the rate or extent of absorption. Different diseases or drugs may alter the mobility. Diarrhea causes rapid peristalsis, decreasing contact time and thus the extent of absorption is affected more.rea of Absorptive Surface. Area of absorptive surface affects oral as well as other routes. Most of the drugs are given orally because of the large area of absorptive surface, so that greater absorption occurs. Intestinal resection decreases the surface area leading to a decreased absorption.

- The surface are of the small intestine is increased by many projections. The increased surface area will allow the small intestine to absorb most of the nutrients of the body. There are blood vessels and vessels contained a fluid called lymph inside the villi. Fat-soluble vitamins and fatty acids are absorbed into the lymph system.

Absorption, Distribution, and Storage of Chemicals For example, chemicals that enter the digestive tract must be absorbed by the cells lining the small intestine and then be transferred through the cell to the other side where the chemical can then be absorbed by the capillary cells into the bloodstream.

How Does the Body Absorb Carbohydrates, Lipids, Fats and Proteins? After digestion, these broken-down fat particles called fatty acids combine with cholesterol and bile to move into your cells' mucosa where they are reconverted into large molecules, most passing into vessels -- called lymphatics -- near the intestine.utrients are important substances that allow your body to perform required daily activities. Carbohydrates, fats and proteins are the major nutrients your body needs for growth, repair, movement and maintaining homeostasis.

What Is a Systemic Viral Infection? A systemic viral infection occurs in many different systems or organs of the body, as opposed to a localized viral infection, which affects only one part or organ of the body. Because viruses are able to reproduce at a high rate, viral infections can spread quickly throughout the body. Keep Learning.

Lipids Digestion and Absorption And, that is exactly what we see happening here in the small intestine. The bile salts break up and coat the fat to form much finer droplets. These finer droplets have more surface area, and this aids digestion because the fat-digesting enzyme pancreatic lipase can only act on the surface of the fat droplet.
