An Experiment To Show The Effect Of Exercise On The Body

Aim
The aim of the experiment is to find out the effect exercise has on the body, and why these changes take place in the body.

Introduction
Respiration is the physical process by which living organisms take in oxygen from the surrounding medium and emit carbon dioxide. The term respiration is also used to refer to the liberation of energy, within the cell, from fuel molecules such as carbohydrates and fats. Carbon dioxide and water are the products of this process, which is sometimes called cellular respiration to distinguish it from the physical process of breathing. Cellular respiration is similar in most organisms, from one-celled organisms such as the amoeba and paramecium to higher animals.

Human Lungs
Though the right lung has three lobes, the left lung, with a cleft to accommodate the heart, has only two. The two branches of the trachea, called bronchi, subdivide within the lobes into smaller a of the body, and carbon dioxide diffuses out of the blood into the lungs, where it is exhaled. And smaller air vessels. They terminate in alveoli, tiny air sacs surrounded by capillaries. When the alveoli inflate with inhaled air, oxygen diffuses into the blood in the capillaries to be pumped by the heart to the tissues.

Prediction
I think that if you exercise for a longer period of time respiration will increase and so will your heart and breathing rate. Our breathing rate increases when we exercise because we are breathing more quickly and because our muscles are working harder they need more oxygen. Also the extra carbon dioxide, which we produce, must be removed quickly otherwise it might build up and poison our tissues. We do not have to think about removing the carbon dioxide as it happens automatically. The senses in the brain detect that there is too much carbon dioxide in the bloodstream, and this automatically causes the body to breathe much faster. We not

    It was stated by heart.org, “Your resting heart rate is the heart pumping the lowest amount of blood you need because you’re not exercising… A lower heart rate is also common for people who get a lot of physical activity or are very athletic. Active people often have lower heart rates because their heart muscle is in better condition and doesn’t need to work as hard to maintain a steady beat.” This means some individuals may last longer or be faster in certain physical situations due to their heart being used to the state or exercise. It would take less energy to do the same physical activities of a fit person than a person who does not exercise “During exercise, blood flow through tissues is changed dramatically. Its rate of flow through exercising…

    When we exercise the body has to work harder, the body temperature would increase this is due to organs having to work harder to get oxygen to muscles. The metabolic rate that produces more energy has to increase in order for more energy to be released. The heart has to pump more blood around the body in order to deliver oxygen to the working muscles so they can carry on working at that capacity.…

    It provides oxygen whilst removing carbon dioxide. The airwauy begins with the nose and the mouth, continues down into the throat, into the bronchi that eventually feed into the lungs. The term respiration means the exchange of gases between body cell and the environment (Waugh & Grant 2014). After absorbing oxygen, the blood leaves the lungs and is carried to your heart. Your heart then pumps it through your body to provide oxygen to the cells of your tissues and organs. As the cells use the oxygen, carbon dioxide is produced and absorbed into the blood. Your blood then carries the carbon dioxide back to your lungs through the capillaries, where it is removed from the body when you exhale.Breathing supplies oxygen and elimates carbon dioxide. Our lungs inflate drawing in air between around 12 to 20 times a minute, as breathing brings oxygen into the body while carbon dioxide is exhaled.…

    Gas and Solute Exchange

    Gaseous exchange is the process by which oxygen is taken in by the body for respiration and carbon dioxide, the waste product of respiration, is released. In humans the lungs are the organ used for gaseous exchange. When we breathe, air moves in and out of the body via our lungs. In the lungs, the air moves into the alveoli and oxygen diffuses into the blood stream. Carbon dioxide diffuses in the opposite direction, from the bloodstream and into the alveoli, where it’s then breathed out into the air. The action of breathing involves muscles contracting and relaxing, depending on whether we want to breathe in or out. Movement of air in and out of the lungs is called ventilation.…

    The gas exchange of oxygen and carbon dioxide takes place in the alveoli. Tiny blood capillaries surrounding the alveolar walls allow oxygen to be carry into the bloodstream. In exchange, carbon dioxide waste diffuses from blood into the alveoli from where it is exhaled. (P. 200)…

    The respiratory system takes oxygen (O2) into the body and eliminates carbon dioxide (CO2). It also enables speech production. Our bodies need energy for movement, growth and reproduction. This energy can only be obtained from the food we eat. By the process of respiration, chemicals of food are eliminated to produce energy that can later be used by the cells of the body.…

    The obvious physiological change that happens when you begin to exercise is the heart rate increases. The more energy and oxygen you use, the harder your heart works to pump the necessary nutrients and release the CO2. When you go from rest to exercise, the increase in heart rate is dramatic then it plateaus. During recovery…

    Carbon dioxide is removed when it combines with potassium hydroxide. This creates a change in volume of the gas in the respirometer. Because the amount of oxygen consumed and carbon dioxide produced have the same molar ratio (6:6), the rate of change in volume of gas is directly related to oxygen consumption, and the rate of cellular respiration.…

    Exercise and Heart

    The overall rate of the heart and breathing increases during exercise. The heart beats faster, allowing blood to supply substances required by the cells to respire. Oxygen is needed to replace the oxygen used up in respiring cells, while at the same time the cells produce carbon dioxide that needs to be removed from the body. The heart rate increases to pump blood around the body quicker, ensuring oxygen is constantly dissociating from the blood to the cells. At the same time the breathing rate increases to increase the rate of gaseous exchange of oxygen and carbon dioxide, and remove excess waste from the body as soon as possible.

    First of all, when a person begins exercising it immediately starts working their heart. When a person’s heart begins working because of exercise it pumps harder; this can lead to a better circulation for blood flow. Since the blood flow is increasing it causes more oxygen to be carried throughout the body. Better circulation due to exercise can also lower one’s blood pressure. All of these can result in a stronger and healthier heart due to working out.…
