All the systems in the human body work together to maintain homeostasis and normal body function. The five major systems are the digestive, circulatory, respiratory, transportation and excretory systems. These systems are then, in turn made of organs, tissue and cells. All the systems are interrelated therefore if one system fails then it impacts the others.
The function of the digestive system in the human body is to break down macromolecules into their individual monomers so the body can process them. There are two major types of digestion that occur in the body. These are mechanical digestion and chemical digestion. Mechanical digestion is the mechanical process of breaking down food particles into smaller pieces. Chemical digestion is the secretion of enzymes and chemicals that break down the food even further into their individual molecules. Some common enzymes in the human body are amylase, pepsin and lipase. Enzymes are catalysts that speed up reactions but aren’t reactants themselves. Different enzymes also react on different substrates, for example, amylase reacts on carboh...
The digestive system otherwise known as the gastrointestinal tract (GI tract) is a long tube which runs from the mouth to the anus. It operates to break down the food we eat from large macromolecules such as starch, proteins and fats, which can’t be easily absorbed, into readily absorbable molecules such as glucose, fatty acids and amino acids. Once broken down, these molecules can cross the cells lining the small intestine, enter into the circulatory system and be transported around the body finally being used for energy, growth and repair.
The whole purpose of your digestion system is to break down and absorb the energy and nutrients it needs from the food you eat. The sandwich, strawberries, and orange juice you have just consumed is going through this process right now! The process of digestion begins with ingestion, this is when you take a bite of what you have planned to eat. When you took a bite of your sandwich and strawberry slices you were essentially beginning the process of digestion. Second comes the job of your digestion, which is a much more time-consuming and complex process for your digestive system. It begins once you have began chewing your food. There are two known types of digestion, these include Mechanical digestion, which is when you “physically break down the food into smaller pieces”, for instance chewing a burger and having it result in several chunks, and Chemical Digestion which is when you chemically break down your food, such as eating a slice of br...
During digestion, the body breaks down food into smaller molecules that could then be used by the body’s cells and tissues in order to perform functions. This starts off in the mouth with the physical movements of chewing and the chemical breakdown by saliva. Enzymes in the stomach break food down further after traveling from the mouth through the esophagus. The food from here then moves into the small intestine, where pancreatic juices and enzymes dissolve proteins, carbohydrates, and fibers, and bile from the liver breaks down fats into these small molecules. Any portion of the fibers or food that were unable to be broken down are passed from the small intestine to the large intestine, which is where the digestive tract transitions into the excretory tract, then the colon and out of the rectum. Any liquids that have been stripped of their nutrients by the body proceed from the stomach to the kidneys. In the kidneys, sodium ions (Na+), uric acid, and urea are exchanged with water, which moves urinary bladder and is excreted through the
Digestion have a function of breaking down all food into our body. Our body use all nutrients to help in the process been health and growth. Digestion supplied small molecules that will be absorbed into our bloodstream.
The Advantages and Disadvantages of Using Enzymes in Medicine and Industry What is an enzyme? = == ==
All organ system work together; in order to keep and support the conditions that the cells, tissues, and organs need to function properly. Each organ system has an important function in the body. There is one system that is not as well known as other; it is the integumentary system. Most people know the organs of the integumentary system, but they do not know that these organs work together to form this system.
Uses of Enzymes in Medicine and Industry. Enzymes are widely used across medicine and industry. Through this essay. I will go through some examples of each case, and explain the complexity of these examples, he said. Enzymes are biological catalysts that enable specific reactions to take place in the future.
The Uses of Enzymes In Industry, Medicine and Analytical and Diagnostic Processes Enzymes are very precise protein molecules with a high specificity which are used to catalyse chemical reactions by lowering the activation energy required for the reaction to take place. It is these properties of being able to break down substances easily and bind specifically to certain chemicals that make enzymes very useful in many industries and practices throughout the world. In addition to this enzymes are not used up in experiments so products of processes are not contaminated with enzyme which could be a problem. This essay explains 3 uses of enzymes, in industry and food, diagnosing and analysing, and treating disease, explaining the function and advantages of enzyme use in each example. In industry enzymes are used for many processes such as brewing beer, baking bread, using pectinase to increase juice in fruit juice drinks and protease enzymes in washing detergents.
The exocrine function of the pancreas is that it produces enzymes that aids in the digestion of food. There are three important enzymes that are crucial in helping with digestion. The first digestive enzyme is amylase. Amylase function is to break down carbohydrates. The amylase enzyme is made in two places: the cells in the digestive tract that produces saliva and the main one specifically found in the pancreas that are called the pancreatic amylase (Marie, Joanne; Media Demand, “What Are the Functions of Amylase, Protease and Lipase Digestive Enzymes”). The amylase in the pancreas passes through the pancreatic duct to the small intestines. This amylase in the pancreas completes the process of digestion of carbohydrates. Consequently, this leads to the production of glucose that gets absorbed into the bloodstream and gets carried throughout the body. The next enzyme that aids in digestion of food is protease. While amylase breaks down carbohydrates, protease breaks down protein. Protease breaks down protein into the building block form of amino acids. The three main proteases that it produces are: pepsin, trypsin and chymotrypsin (Marie, Joanne; Media Demand, “What Are the Functions of Amylase, Protease and Lipase Digestive Enzymes”). Pepsin does not occur in the pancreas but it is the catalysis in starting the digestion of proteins. Trypsin and chymotrypsin are the two proteases that occur in
The human body is mixture of cells that make up tissues that make up organs that make up organ systems. The organ systems that are going to be wrote about is the digestive system, the circulatory system, the respiratory system, the nervous system, and the skeletal and muscular system; all these systems are what make the human body function the way it does. The cells have to communicate to get some of these jobs done, and I will write about how cells do communicate to get the jobs done. The body’s systems interact to maintain homeostasis, homeostasis is the equilibrium of the body. The systems work together through communication to maintain homeostasis and the
The human body is very complex. It is like a job. You have to do a million things in one day to make it through the day. The body uses nine systems to do all of those jobs. They all have separate functions, but some work together. Each system is also made up of organs. There are many ways to care and protect the systems from the many different problems they can have. There are also many interesting facts about each system.
The digestive system is very responsible for taking the whole food that people eat and turns them into energy and nutrients to allow the body to function, grow, and fix itself. The six primary processes of this system are ingestion of food, secretion of fluids and digestive enzymes, mixing and movement of food and waste throughout the body, digestion of food into small pieces, absorbing the nutrients, and the elimination of wastes. Ingestion is the first function of the digestive system, which is also known as the intake of food. The mouth is the reasoning for this process because through the mouth is the way food enters the body. The stomach and the mouth store food until your stomach is ready to digest the food that was just eaten. The reason why people can only eat a few times a day is because your body can only allow a certain amount of food depending on your body weight and type, and it cannot ingest more food than it can process at one time. The next step in Secretion, this happens in the course of the day. The digestive system secretes about 7 liters of fluid daily, but these fluids include saliva, mucus, hydrochloric acid, enzymes, and bile...
Both chemical and mechanical digestion begins in the mouth as food materials are broken down into more absorbable units. Food material is transported down the gastrointestinal tract though muscle contractions, a process known as peristalsis. An enzyme known as Amylase, whose main function is to break down carbohydrates, is produced in the salivary glands and pancreas
The relationship between the basic functions of the human body and its organs are explained as follows: the body is made up of organs which form part of a number of systems which maintains and keeps the body functioning. The nervous system, circulatory system, digestive system, respiratory system, cardiovascular system, respiratory system, immune system, excretory system, etc, all operate in order to have the body function properly.
One system is the skeleton, which serves to support the body and protect the internal organs. The respiratory system enables us to breathe and take oxygen into the blood, which moves around the body by means of the circulatory system. The digestive system enables us to take in food needed for growth. Waste matter is ejected from the body by means of the urinary system. The nervous system controls the other systems and enables human beings to think.
