P4- Explain the physiology of two named body systems in relation to energy metabolism in the body.
Energy is the strength and ability that is required in order to perform physical or mental activities. There are different forms of energy these consist of: magnetic, kinetic, heat, light, gravitational, chemical, sound, electrical, elastic and nuclear.
The law, conservation of energy states that the total amount of energy within a system remains constant at all times, although energy within the system can be changed from one form to another. Energy cannot be created or destroyed, but it can be transformed. The law of conservation of energy states that when energy is being used, it’s not being used up instead it’s being transformed from

The network of alveoli, bronchioles and bronchi is also known as the bronchial tree.
Gas exchange is when oxygen is delivered from the lungs to the blood stream and carbon dioxide is taken out of the bloodstream and into the lungs. Gas exchange occurs within the lungs between the alveoli and capillaries which are in the walls of the alveoli. The walls of the alveoli share a membrane with the capillaries in which oxygen and carbon dioxide move freely between the respiratory system and the bloodstream. Oxygen molecules attach to red blood cells, which travel back to the heart. At the same time, the carbon dioxide in the alveoli are exhaled out of the body.
The thorax is similar to an airtight box that holds the bronchial tree, lungs, heart, and other structures. The top and sides of the thorax are formed by the ribs and attached muscles, and the bottom is formed by diaphragm which is a large muscle. The chest walls form a protective cage around the lungs and other contents of the chest cavity.
The diaphragm separates the chest and the abdomen as well as this it has a large role in breathing. The diaphragm moves down when we breathe in which expands the chest cavity making room for air to enter through the nasal cavity or mouth. When we breathe out the diaphragm moves upwards, forcing the chest cavity to reduce in size and pushing the gases in the lungs up and out of either the nose or mouth.
Oxygen is required by cells to allow various

Energy it is the ability to do work. Energy cannot be destroyed but it can be changed to another form. Without energy we would not be able to growth or move. To stay alive we need regular and permanent supply of energy or else we would die. Without energy our body would not be able to carry out processes such as:
The respiratory system is made up of organs and tissues that help you breathe. The main parts of this system are the lungs, the trachea, the diaphragm, alveoli and nasal cavity. The respiratory system starts with the mouth and the nose, where air is brought in, then passes through the larynx and the trachea into the chest cavity. http://www.nhlbi.nih.gov/health/ health-topics/topics/hlw/system The main organs of the respiratory system are lungs, which carry out this exchange of gases as we breathe. The
Energy can be transformed but cannot be got rid of. There are lots of forms of energy but chemical energy is the most common form of energy. Energy is a chemical bond that combines atoms or molecules with each other. When the new bond is formed between to atoms the energy helps the formation. The energy that helps is normally heat energy but can also be light or electrical. When the bond is broken atoms get realised as does the energy in the bond.
Explain The Physiology Of Two Named Body Systems In Relation To Energy Metabolism In The Body
The act of breathing starts from the mouth. You breathe in air through your mouth and nose, and it travels through the back of your throat and down your wind pipe or trachea. Your trachea the divides itself into air passages called bronchial tubes. For your Lungs to perform at their best these passages needed to be clear during inhaling and exhaling. And free from mucus swelling and inflammation.
Energy is expended in a number of different ways such as the stated above; resting metabolic rate, thermic effect of activity, thermic effect of feeding and adaptive thermogenesis. An individual’s energy balance is the balance of calories consumed through eating and drinking compared to calories burned through physical activity, what an individual drinks and eat is energy in. what an individual burns though physical activity is energy out. Body weight is maintained and stable in the state of energy balance, the chemical bonds of carbohydrates, proteins and fats in food contain chemical energy which is then transformed in the human body in multiple metabolic processes to cellular energy, heat or stored energy. An individual’s burns a certain number of calories just by breathing air and digested food. They also burn a certain number of calories through their daily routine, an important part of maintaining energy balance is the amount of physical activity an
The respiratory system and the cardiovascular system work together by oxygen being inhaled by the mouth and nostrils and then the oxygen enters the respiratory system. When the oxygen enters the respiratory system, oxygen enters the alveoli which are located in the lungs and then it diffuses through the alveolar wall. After when this process is complete, it enters the cardiovascular system. The oxygen is then mixed with hemoglobin, which forms oxyhaemoglobin. The blood is then circulated all around the body. While the blood is mixed with the oxygen, a waste gas gets produced, which is carbon dioxide. The excess gas then exists out by going through the respiratory system and then it is exhaled out from the mouth.
We know that there are different types of energies that we know of which are: chemical, light, sound, heat and electrical. When looking at our bodies, we know that we need energy to help our bodies to function and the energy that we use in our body is chemical. The reason for this is that the energy help circulate the blood through in our bodies as it carries the oxygen to help with breathing and for the growth and repair for new of damaged cells in our bodies. Also the energy helps to transfer information in out nerve cell to help us respond the environment about us and this is all a part of Energy Metabolism.
The human muscular system is made up of over 600 connecting muscles. All of the muscles work together in sync to make your body move in inumerable different ways.
Air enters your lungs through a system of pipes called the bronchi. These pipes start from the bottom of the trachea as the left and right bronchi and branch many times throughout the lungs, until they eventually form little thin-walled air sacs or bubbles, known as the alveoli. The alveoli are where the important work of gas exchange takes place between the air and your blood. Covering each alveolus is a whole network of little blood vessel called capillaries, which are very small branches of the pulmonary arteries. It is important that the air in the alveoli and the blood in the capillaries are very close together, so that oxygen and carbon dioxide can move (or diffuse) between them. So, when you breathe in, air comes down the trachea and through the bronchi into
The lungs are sponges that fill with air, and fill every inch the surrounding thoracic cavity. The lungs contain lobes. The lobes divide each lung, and the right lung being bigger has more lobe divisions. The pulmonary veins enter here and exit here as well. Inside the lungs are clusters of air sacks that are called alveoli. The alveoli are part of the bronchioles that enter each lung. The oxygen and carbon dioxide are exchanged in the lungs. The exchange happens from a small blood vassal nod the alveoli. When the oxygen exchange is completed the inhaled air moves into the blood. While the oxygen moves into the blood the carbon dioxide is exhaled by the lungs. Before the blood can be moved properly it has to be made into oxyhemoglobin.
The main organs of the respiratory system are the lungs – they are the location where the gas exchange between oxygen and carbon dioxide takes place. The lungs therefore expand when you breathe in, and retract when you breathe out. This is done through the diaphragm – a sheet of muscle that is positioned under the lungs. As one inhales, their diaphragm contracts and moves itself downward, increasing the space for your lungs to expand to. The ribs also move to enlarge the possible area the lungs can expand to. This pressure causes air to be sucked through the body to the lungs. When one exhales, the opposite takes place – the diaphragm moves upwards and returns to normal, allowing the process to happen again.
As we breathe in, the muscles in the chest wall force the thoracic area, ribs and connective muscles to contract and expand the chest. The diaphragm is contracted and moves down as the area inside the chest increases as air enters the lungs. The lungs are forced open by this expansion and the pressure inside the lungs becomes enough that it pulls
What is energy? Energy is the ability to do work, it is the “power that comes from the use of physical or chemical resources.” In your home energy can come in many forms such as heat, light, and even electricity. The problem is some of us, meaning people, in general, know little to anything about the word energy itself. When we think about energy, we think about the energy it takes to get up in the morning. Sometimes as students we do not notice how much, and when we use energy. We use energy in everyday life, and it is very important to understand that.
