midgut and hind gut and are about 150 in number. They are fine‚ yellow coloured and branched threads present in bundles. They lie freely in the haemolymph. The distal parts of the tubules extract inorganic ions‚ uric acid and amino acids by active transport and water by diffusion from the surrounding haemolymph. The filtrate moves towards the ileum. In the proximal parts of the malpighian tubules water and other useful substances are reabsorbed. The remaining materials passes into the gut. More water

it enters the esophagus. The esophagus transports liquids and food from the back of the throat to the stomach. The esophagus is the simplest of the organs in the digestive track. It is comprised of two types of muscles: striated muscle and smooth distal muscles. This organ is bound by the upper and lower sphincters. During swallowing the muscles relax moving the larynx forward and assisting in the routing of food (The Esophagus). After the food passes through the esophagus‚ it transitions into the

intracellular vesicles with the cellular membrane. The SNARE complex is made up of 2 classes of protiens that allow vesicle fusion called the v-snares and t-snares. The v-snares are found on the vesicle and include synaptobrevin. The t-snares are located on the target membrane and has two components called syntaxin and SNAP-25 (Karp‚ 2008). The SNARE proteins are fixed tightly within the vesicle and target membrane by transmembrane domains. When the target membrane and vesicle come into contact and

In this assignment I will explain the physiology of two named body systems in relation to energy metabolism in the body. I will be explaining two body systems these are Respiratory system and Digestive system. Energy According to Wright (2007)‚ we need energy for everything we do. Energy can be found in different forms including chemical energy‚ electrical energy‚ thermal energy‚ radiant energy‚ mechanical energy and nuclear energy. We use energy all the time including when we are sleeping. We

What is lactase deficiency? -Lactase deficiency is a deficiency in the enzyme that breaks down lactose. The causes of lactase deficiency include congenital defects‚ secondary lactase deficiency‚ and primary (acquired). 3. Define lactose maldigestion‚ identify the potential etiologies of lactose maldigestion‚ and describe

Nutrition: Barriers to Digestion Lactose Intolerance: - Lactase is one of the many enzymes required for complete digestion of lactose (a disaccharide). - Lactose intolerance is not an allergy‚ and is not to be confused with a milk allergy‚ which initiates an immune reaction when milk is ingested. Lactose intolerance instead is an enzyme deficiency (lactase). - S/s including gas‚ bloating‚ cramping‚ nausea‚ and diarrhea. Some people can ingest small amounts‚ and others none. Some can take
