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...
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
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.
All 4 systems, cardiovascular, digestive, respiratory and excretory all aid the body in maintaining homeostasis through the exchange of gases and molecules throughout the body. The respiratory and cardiovascular systems work together to insure all parts of the body have an adequate oxygen supply for every cell to carry out cellular respiration. Deoxygenated blood is pumped from the heart to the lungs where it captures oxygen molecules and transports them from the lungs to around the body until the blood is deoxygenated again. Both systems are also used to remove CO2 from around the body by following the opposite path and exhaling it as waste. The cardiovascular system also works with the digestive system to transport molecules and nutrients needed for cellular respiration. In the digestive system complex molecules are broken down into smaller, simpler molecules like glucose. These molecules are then
Organ systems like the integumentary, skeletal, nervous, and endocrine all play a big role in helping the body maintain homeostasis. The integumentary system helps maintain by giving protection, regulating body temperature, and sensory receptors. All of this plays a big role maintaining the internal conditions so the body may function. The skeletal system helps by producing red blood cells in place of the old ones that die. It also helps to maintain the calcium levels in our blood stream. The nervous system maintains homeostasis by controlling and regulating other parts of the body like letting you know when you’re tired or when you’re hungry. It makes sure the body is acting how it should by using receptors. The endocrine system releases hormones that are sent to different parts of the body that control the body’s reaction to things like stress, pain, and growth. These hormones give directions to the body for the fight or flight response so that it can adjust and maintain
Food and drink must be changed into smaller molecules of nutrients to be absorbed into the blood and carried to cells throughout the body. Digestion is the process by which food and liquid are broken down into smaller parts so that the body can use them to build and nourish cells, and to provide energy. Digestion involves the mixing of food, the movement of food through the digestive tract, and a chemical breakdown of large molecules of
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
There are many body systems located within the human body that help us live. These body systems also help people function properly. Breathing, feeling pain, digesting food, and excreting waste are all due to the body systems, and how they function are just as important.
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 Digestive system is a group of hollow and solid organs working together to convert food into energy and basic nutrients to feed the entire body. These nutrients are used for energy, growth and cell repair. Once the food enters the mouth it passes through a long tube inside the body which has many names such as the alimentary canal, the gastrointestinal tract also known as the GI tract or the digestive tract. The process starts at the mouth and ends at the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine which includes the rectum and anus. The solid organs of the digestive system are the liver, pancreas, and the gallbladder. Once we ingest the food the body digests the food and is broken down into its own component chemical. The body must perform six major functions in order to provide energy and nutrients to the body, these functions are ingestion, secretion, mixing and movement, digestion, absorption and excretion.
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 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
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 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...
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.
