This is digested and the glycosidic bonds are hydrolysed by amylases and lactases etc. to leave us with glucose monomers, which can be absorbed into the bloodstream, usually in the microvilli in the small intestine, which have a huge surface area and a good blood supply The glucose is then carried around in the blood plasma Once inside the lumen of the nephron, small molecules, such as ions, glucose and amino acids, get reabsorbed from the filtrate: Specialized proteins called transporters are located on the membranes of the various cells of the nephron. These transporters grab the small molecules from the filtrate as it flows by them Amino acids, short fatty acids, and monosaccharides (sugars) are transported from the intestinal cells into capillaries, but the larger fatty acids, fat-soluble vitamins, and other lipids are transported first through lymphatic vessels, which soon meet up with blood vessels. Figure 2.8 Structure of the Small Intestin The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body Ans : (b) They make a large surface area for absorption Structure X shows microvilli, which increases the surface area for absorption of digested products i.e., amino acids, glucose etc. 14.

These microvilli further enhance the absorption of glucose and other simple molecules like amino acids. The villi are composed of the folding of lamina propria and the gut epithelial cells of the.. When you eat food, you take in large molecules called macromolecules that are made up of building blocks that you can absorb into the bloodstream, and that your cells can burn for energy. Your digestive tract breaks down these macromolecules to liberate their building blocks so that the small intestine can absorb them Liver cells deal with nutrients such as glucose, fats, and amino acids that were absorbed by the small intestine into the bloodstream so they can regulate their levels in the blood. They also store certain minerals and vitamins, remove poisonous substances from the blood, and break down hormones to stop them from working Importance of Circulatory system. Helps in excretion of waste products from the body; Digested food materials like glucose, amino acids, fatty acids and glycerol are carried from the intestine to the tissues where they are stored or used up, water and oxygen are also carried by the blood. Protection of the body against diseases e.g. white blood.

The cells then transfer these fatty acids into the lacteal found in the villus, which connects to the lymph system. The amino acids and simple sugars (i.e glucose) must be transported across the cell membrane via either active or passive transport, and are eventually transferred directly into the blood vessels found in the villi Absorption. Absorption is the movement of digested food molecules through the wall of the intestine into the blood or lymph. The small intestine is the region where digested food is absorbed. Most. Renal release of glucose into the circulation is the result of glycogenolysis and gluconeogenesis, respectively involving the breaking down and formation of glucose-6-phosphate from precursors (eg, lactate, glycerol, amino acids)

How Is Glucose Transported in the Circulatory System

Water, glucose, and amino acids (all of which have a much smaller molecular mass than large plasma proteins) are commonly found in the filtrate. Amino acids, glucose, and some water are reabsorbed. 1. The function of the digestive system is to break food down into nutrients that are then absorbed and transported by the circulatory system. The end products of digestion are glucose, amino acids, fatty acids, and glycerol. 2. In order, food passes through the following digestive structures: mouth (teeth begin mechanical digestion, salivar In the stomach, proteins are broken down into peptides, which are then broken down into single amino acids that are absorbed in the bloodstream though the small intestine. Lipids are digested mainly in the small intestine by bile salts through the process of emulsification, which allows lipases to divide lipids into fatty acids and monoglycerides For instance, carbohydrates are broken down into glucose, proteins into amino acids, and fats into fatty acids and glycerol. The digestive system involves hollow organs and solid organs

Glucose - this is one of the most important forms of sugar used by the body for energy. All other carbohydrates (including other sugars) are converted into glucose during the digestion of food. Glucose is naturally found in some fruits and vegetables and the nectar or sap of plants. Fructose - is also known as fruit sugar, and is the main. Blood is a connective tissue of the circulatory system and the fluid in the body that transports absorbed nutrients to cells and waste products from cells. The fluid part of blood, plasma, makes up the largest amount of blood volume and contains proteins, ions, glucose, lipids, vitamins, minerals, waste products, gases, enzymes, and hormones Glucose, amino acids, water, mineral salts and some other substances leave the loop of Henle to pass into the blood capillaries that surround it. 4. Ureter: From the hilum of a kidney, arises a narrow tube which carries the urine collected in the pelvis of the kidney to the urinary bladder which is situated at the base of the abdomen

The Digestive & Circulatory Systems Converting Food Into

Describe the structure and functioning of nephrons. Answer: Each kidney has large numbers of filtration units called nephrons packed close together. Functions of nephrons: Some substances in the initial filtrate, such as glucose, amino acids, salts and a major amount of water, are selectively re-absorbed as the urine flows along the tube This filterate contains glucose, amino acids, urea, uric acid, salts and a major amount of water. (ii) Reabsorption: As the filterate flows along the tubule useful substances such as glucose, amino acids, salts and water are selectively reabsorbed into the blood by capillaries surrounding the nephron tubule Most of the absorption of digested food into circulatory system occurs in the ileum. Glucose, amino acids, water-soluble vitamins and minerals are absorbed by diffusion and active transport into the blood capillaries. These capillaries unite to form the hepatic portal vein, which carries food to the liver Almost 100 percent of glucose, amino acids, and other organic substances such as vitamins are normally recovered here. Some glucose may appear in the urine if circulating glucose levels are high enough that all the glucose transporters in the PCT are saturated, so that their capacity to move glucose is exceeded (transport maximum, or T m )

The glucose molecule is small enough to be absorbed directly through the walls of the digestive system. Starch is a polymer of glucose . It must be broken down into glucose molecules - it is too. • The digestive system brings in food and breaks it down into smaller molecules, such as glucose and amino acids, that can fit into cells. • The circulatory system transports glucose, oxygen, and amino acid molecules to every cell in the body. • In a functioning human body, body systems work together to deliver glucose, oxygen, and amino.

Digestion and Absorption of Carbohydrates, Proteins, and Fats. Carbohydrates, fats, and proteins are the major nutrients the body needs for growth, repair, movement, and maintaining tissue and organ function.; These macromolecules are broken down and absorbed into the body at different rates and into specific forms as they travel through the organs in the digestive system Glucose, amino acids, minerals, vitamins B and C are absorbed into blood capillaries of the villus and carried out of the small intestine to the liver by the hepatic portal vein. 2. The hepatic portal vein transports the nutrients absorbed from the small intestine to the liver for processing and prepared for metabolic process or assimilation An open circulatory system blood is pumped into body cavities where it bathes the surrounding cells. This is a low pressure system and found in organisms such as snails and insects. Peptidases break any remaining peptide bonds into amino acids. Nucleotidases break the monomers into their three components for absorption It carries nutrient material, glucose, amino acids and fatty acids, vitamin, electrolytes and trace elements from alimentary canal to the tissue. 3. Excretory: It carries waste materials, the products of metabolism such as urea, uric acid, creatine, etc. away from cell. Trim ethylamine oxide (TMAO) is present in all fishes

Many, but not all, amino acids are taken up by cotrans-port with Na + similar to glucose cotransport (figure 16.27). Within the intestinal epithelial cells, tripeptides and dipeptides are broken down into amino acids. The amino acids then enter blood capillaries in the villi and are carried by the hepatic portal vein to the liver Villi contain a lacteal, which is part of the lymph system, capillaries are found close to the surface of the villi and are connected to a rich blood supply. Some substances such as lipids are absorbed by the lacteal others such as glucose and amino acids are absorbed into the blood (capillaries)

The absorption process also occurs in the small intestine. Food has been broken down into particles small enough to pass into the small intestine. Sugars and amino acids go into the bloodstream via capillaries in each villus. Glycerol and fatty acids go into the lymphatic system. Absorption is an active transport, requiring cellular energy Glucose. Amino acids. Vitamins. Na+. K+. HCO. 3-Water. Ca2+ Mg2+ Interstitial. Fluid. Under normal circumstances, before the tubular fluid enters the loop of Henle, the PCT reabsorbs more than 99% of the glucose, amino acids, and other organic nutrients (b) The blood from stomach and intestines enters the liver via hepatic portal vein because the liver monitors all the substances that have to be circulated in body.

Insulin is a protein composed of two chains, an A chain (with 21 amino acids) and a B chain (with 30 amino acids), which are linked together by sulfur atoms. Insulin is derived from a 74-amino-acid prohormone molecule called proinsulin.Proinsulin is relatively inactive, and under normal conditions only a small amount of it is secreted 4 Normal Digestion Nutrient Digestion they are mixed with enzymes and buffers from profuse pancreatic secretions to start breaking down the food products into glucose, amino acids, free fatty acids and monoglycerides. Pancreatic enzymes are released in an inactive form (zymogen) and must be activated. The simpler components are absorbed. B. active transport of glucose into a villus. C. hydrolysis of a peptide into amino acids. D. release of secretin in the presence of HCl. 66. E. coli are beneficial to humans because they A. convert pepsinogen to pepsin. B. produce vitamins and amino acids. C. absorb water from the large intestine. D. synthesize urea from the breakdown of amino. If you go without eating for an extended period or simply consume too little carbohydrate, your glycogen stores will quickly deplete. Your body will grab protein from your diet (if available), skeletal muscles and organs and convert its amino acids into glucose (gluconeogenesis) for energy and to maintain normal blood glucose levels
