The circulatory system is consist of a heart, blood vessels and blood, and is liable for transporting life-giving oxygen all over body. While exercise, body’s need for oxygen rises; the harder the work out, the more oxygen body demands. To make sure that the sufficient oxygen is offered for muscles during activity, body makes short- and long-term fluctuations.

Exercise and Heart
The heart -- stated to as the myocardium, meaning heart muscle -- is a four-chambered pump about the size of a fist, positioned slightly left of center in a chest. Its work is to pump blood. While performing exercise, a heart rate can rise from a resting average of 72 to 200 beats per minute, depending on the fitness level and age. As getting fitter, a heart becomes stronger and resting heart rate decreases.
Exercise uses up a lot of energy, which the cells develop from oxidizing glucose. Both glucose and oxygen have to be carried by the blood. This means that the heart has to work harder to pump more blood over the body. This means it has to beat faster in demand to reach at higher quantity, as termed by this equation:
Blood flow = heart rate x stroke volume [Math Arizona, 1999]
Heart rate for a human being at rest is about 70 beats/min. throughout vigorous exercise, heart rate can increase intensely (the rule of thumb specified for maximal heart rate is 220 minus your age). This will outcome in an increase in blood flow. [Live strong, 2015]

Exercise and Blood Vessels
Blood vessels transport blood all over the body. Arteries help to take blood away from the heart; veins return blood to the heart, and capillaries drop off and bring together the blood into the muscles and lungs. During exercise, the hormone adrenalin causes the blood vessels to expand t...

...prove circulation. In response to the necessity to supply the muscles with more oxygen throughout exercise, the body increases its number of capillaries which are the smallest blood vessels in the body. Remaining capillaries also open wider.
4. Also, Blood pressure is decrease by up to 10 mmHg. An mmHg is a unit used for measuring pressure levels.
5. Blood volume upsurges. The body produces a bigger number of erythrocytes in order to keep the muscles supplied with oxygen throughout heavy exercise. [Fitness Health Wellness, 2015]

Importance
The cardiovascular system secures a numerous of profits from regular exercise assisting to live healthier life and age strong. Any form of exercise such as, aerobic exercise, from swimming and running to dancing or skateboarding, they play an essential role to strengthen the cardiovascular system.

  • Determination of Maximal Oxygen Consumption Lab Report

    In this lab, we explored the theory of maximal oxygen consumption. “Maximal oxygen uptake (VO2max) is defined as the highest rate at which oxygen can be taken up and utilized by the body during severe exercise” (Bassett and Howley, 2000). VO2max is measured in millimeters of O2 consumed per kilogram of body weight per min (ml/kg/min). It is commonly known as a good way to determine a subject’s cardio-respiratory endurance and aerobic fitness level. Two people whom are given the same aerobic task (can both be considered “fit”) however, the more fit individual can consume more oxygen to produce enough energy to sustain higher, intense work loads during exercise. The purpose of this lab experiment was performed to determine the VO2max results of a trained vs. an untrained participant to see who was more fit.

    The blood circulates through coronary arteries and then to smaller vessels into cardiac muscle (myocardium). The blood flow is influenced by aortic pressure, which increases in systole, and the pumping activity of the ventricles. When the ventricle contracts, in systole, the coronary vessels are compressed by the contracted myocardium and partly blocked by the open aortic valve therefore the blood flow through the myocardium stops.

    The heart is an extraordinary structure that is the base of all human life. However, it similar to the uncomplicated functions of water pumps. As the heart beats, blood is distributed throughout the body using a network of blood vessels. The functions of the heart can be kept in regular and healthy conditions through exercise. Exercise has an effect on the blood that is circulating through the body. That circulating blood makes the heart desire more oxygen, causing the heart rate to increase rapidly to keep up with activity demand.

    The extra heat produced during metabolic exchange, raises the body temperature again affecting the enzymes and heat is then removed by sweating. If the body isn’t kept hydrated during exercise, dehydration will occur, causing the blood to become concentrated. When the blood becomes concentrated, the cells no longer have enough water to function.

    During the first one or two minutes of exercise, before the heart has pumped enough oxygenated blood to the working muscles, the muscles are powered by anaerobic energy. In order for these muscles to continue exercise, the body must supply them with continuous supply of oxygen, the more efficiently this is done, the better the cardiovascular fitness level. During cardiovascular conditioning, a program such as interva...

    These results make sense because the heart beats faster in order to keep the body’s cells well equipped with oxygen. For one to continue exercising for long amounts of time, cells need to create ATP in order to use energy. Oxygen must be present for the process of creating ATP, which not only explains why higher respiratory rates occur during exercise but also faster heart rates. When the heart is beating rapidly, it is distributes oxygenated blood as fast as the body n...

    The heart is two sided and has four chambers and is mostly made up of muscle. The heart’s muscles are different from other muscles in the body because the heart’s muscles cannot become tired, so the muscle is always expanding and contacting. The heart usually beats between 60 and 100 beats per minute. In the right side of the heart, there is low pressure and its job is to send red blood cells. Blood enters the right heart through a chamber which is called right atrium. The right atrium is another word for entry room. Since the atrium is located above the right ventricle, a mixture of gravity and a squeeze pushes tricuspid valve into the right ventricle. The tricuspid is made up of three things that allow blood to travel from top to bottom in the heart but closes to prevent the blood from backing up in the right atrium.

    Investigating the Effect of Exercise on the Heart Rate Introduction For it's size the heart has the huge capacity of pumping large amounts of blood, in the average adult's heart beats 60 to 100 times a minute, pumps between 70ml and 100ml of blood with each beat, circulates 5 to 6 litres of blood around the body per minute and about 13 litres of blood per minute during vigorous exercise. The heart will beat more then 2.5 billion times during an average lifetime. This investigation will be looking at the effect of exercise on the heart rate. Aim The aim of this investigation is to find out how exercise affects the heart rate, using research & experimenting on changes and increases in the heart rate using exercise. Research â— The heart The normal heart is a strong, hardworking pump made of muscle tissue.
