Unit 5 Anatomy and Physiology for Health and Social Care P4 Explain the physiology of two named body systems in relation to energy metabolism in the body The two body systems selected in relation to energy metabolism in the body are the digestive system and cardiovascular system. The digestive system breaks down foods and the cardiovascular system enables absorption and usage of the food. The term energy metabolism in the body relates to chemical reactions that that maintain cells and organisms. It is divided into two categories: catabolism is the breakdown of molecules to obtain energy and anabolism the synthesis of all compounds needed by the cells. Metabolism is responsible for converting nutrients in food that we eat in to energy. We need …show more content…
Energy is also needed to circulate blood, breath, take in oxygen, make new cells, grow, repair, and to transmit nerve impulses to react to changes in the environment. For example, moving quickly to get out of danger or recognising the best course of action to take in an emergency situation. Energy is also needed to build complex molecules such as enzymes and hormones from the simple molecules produced after we digest food and drink. A constant supply of energy is needed by the body and cells to enable all of these activities, and without this energy we would be unable to function as living beings. The main function of food that we eat and what we drink is to supply enough energy to support functions of the body. The cells of the body break down the energy provided in the food through a system known as cellular respiration. Cellular respiration means the food is broken down by the cells to produce the energy which is in the form of ATP molecules (Adenosine Tri Phosphate). Cellular respiration is the process of changing food molecules to water, carbon dioxide and …show more content…
The proper functioning of one system relies on the proper functioning of the other system. In other words, the digestive system needs to be in good working order to support the functions of the cardiovascular system. An example of the digestive and cardiovascular systems interrelating is: the first step in digestion of fat is to dissolve it into the intestine where bile acids produced by the liver dissolve the fat into fatty acids and cholesterol. The bile acids join with the fatty acids and cholesterol and vessels then carry the changed fat to the veins of the chest, and the blood carries the fat to storage in different parts of the body. This is how the two body systems interrelate, and therefore if food isn’t eaten or the digestive system breaks down the cardiovascular system will also be affected. The two systems also interrelate during digestion of food and drink when the body produces enzymes to break down the food into smaller pieces and the nutrients from the food are absorbed in the intestines and into the bloodstream. The blood then flows, spreading the nutrients throughout the body. As the blood circulates, the toxins produced by the digestive system are transported through the cardiovascular system to the kidneys to get rid

Carbs and fats are needed in the diet for energy but proteins are not intended to be used as energy. What do they do for the body instead? List a few of the functions of proteins. Type your response here: Proteins do so much for the body. They help with your hair and nails.
The stomata are the most critical piece to this process, as this is where CO2 enters and can be stored, and where water and O2 exit. Cellular respiration also known as oxidative metabolism is important to convert biochemical energy from nutrients in the cells of living organisms to useful energy known as adenosine triphosphate (ATP). Without cellular respiration living organisms would not be able to sustain life. This process is done by cells exchanging gases within its surroundings to create adenosine triphosphate commonly known as ADT, which is used by the cells as a source of energy. This process is done through numerous reactions; an example is metabolic pathway.
The digestive system is responsible for chemically and mechanically breaking down food and includes organs such as, mouth, esophagus, stomach, small intestine, rectum, anus, and additional accessory organs. These organs all aid in the breakdown of food. Food is broken down mechanically by chewing and churning in the stomach, and chemically by acidic enzymes in the stomach and in the small intestine which receives enzymes from the pancreas that are specifically designed for the breakdown of nutrients. Once the food and nutrients are broken down, the excretory system removes whatever the body decides is waste by filtering blood in the nephrons of the kidneys and turning it into urine which is then collected in the bladder and removed from the body when the bladder is
Growth, metabolism and repair take place within the body by getting nutrients from food. A varied diet is key in order to obtain the correct balance of nutrients (and that enough are supplied). Thus the main goal of nutrition is to stick to a healthy lifestyle for the benefit of all cells in the body. Leading a healthy
Role of Enzymes in Metabolic Pathways Summary Metabolic pathways are a sequences of steps found in biochemical reactions in which the product of one reaction is the substrate for the next reaction . Metabolic pathways most likely happen in specific locations in the cell. The control of any metabolic process depends on control of the enzymes responsible for the reactions occur in the pathways. After food is added to the body, molecules in the digestive system called enzymes break proteins down into fats into fatty acids, amino acids, and carbohydrates into simple sugars (for example, glucose). Enzymes plays an important role in the different metabolic pathways .
Cellular Respiration One of the main essentials of life that all organisms need in order to function in our world is, energy. We receive that energy from the food that we eat. Cellular respiration is the most efficient way for a cell to receive the energy stored in food. In cellular respiration, a catabolic pathway, which breaks down the molecules into smaller units, in order to produce adenosine triphosphate, also known as, ATP. ATP, is used by cells in the act of regular cellular operations, it is a “high energy” molecule.
The Digestive System The digestive system is a system consisting of the mouth, oesophagus, stomach, gallbladder, small intestine, large intestine, the rectum and the anus. The functions of the digestive system are: • To break down food particles into molecules for digestion • To absorb into the bloodstream the small molecules produced by digestion • To eliminate un digested and unabsorbed foodstuffs and other waste products from the body The full digestive process begins at the mouth. The food enters the mouth and is chewed.
In the human body, one of the essential systems is the digestive system, which breaks down the foods what we eat into nutrients such as proteins, carbohydrates, vitamins and fats. The bloodstream would be absorbed by them. Therefore, it provides the body with energy, repair and growth. Also, the three types of processes that food passes through in the human body are digestion, absorption and elimination. The digestive system prepares the body cells for nutrients through six activities: Ingestion, Mechanical digestion, Propulsion, Chemical digestion, Absorption and Defecation.
Introduction This document illustrates answers to questions posted as a case study where a patient suffers from two arrow wounds. One running anteriorly between the 7th and 8th ribs at a 15-degree angle through the head protruding posteriorly, and another in the posterior cervical triangle. Solution to Question 1a.
Cellular Respiration: The Soul of Energy On a warm summer day in England, a boy named Ciel was writing letters. After the letters were finished, Ciel went to the kitchen to get a drink of tea. Little did he know, that when he drank the tea a three-staged process called Cellular Respiration was taking place in his body.
The digestive system is located around the stomach area. Along with the digestive system, many other organ systems all work together to create an organism. An example of this would be if a person eats a sandwich and then goes for a run. During the run, the circulatory system helps the body breathe, the muscle system helps the bones move, and all the while the digestive system digests the food. Later on, the excretory system gets rid of the waste, or food that the body can’t use for nourishment.
The adrenals are known for making the hormone adrenaline but also, they make the corticosteroids which affect your metabolism and sexual function. The pancreas is part of the the digestive system and the endocrine system. It makes the hormones insulin and glucagon. These help ensure you have the right amount of sugar in your bloodstream and your cells. If you don 't make any insulin, which is the case for people with type one diabetes, your blood sugar levels can get dangerously high and if the body makes some insulin but not enough, that is type two diabetes.
Building Strong Relationship with Positive Energy Energy Energy is defined as the capacity for work or the force that helps us do things with vitality and intensity. This energy would be further classified into Negative or Positive; Negative Positive Negative, stressful work environments results in - Physical fatigue - Decreased optimism - Lower morale Positive, work climate makes workers feel - Uplifted - Encouraged - Empowered
