Extracts from this document...

Introduction

The cardiovascular system The cardiovascular system is made up of the heart and the blood vessels, such as the veins and arteries, which move the blood around the body. Your heart is a muscle that is about the size of your fist. It works like a pump and it is always pumping blood throughout the body. Blood carries oxygen from the lungs and nutrients from the digestive system to the cells in the body. The blood then carries waste products back to be removed by the kidneys and carbon dioxide to be removed by the lungs. Arteries carry oxygen-rich blood away from the heart. The main artery from the heart is the aorta. Veins carry oxygen-poor blood back to your heart. At the lungs, it is the pulmonary artery that brings oxygen-poor blood into the lungs and the pulmonary vein that carries oxygen-rich blood back to the heart. It picks up oxygen and comes back to the heart at the left atrium. From there it passes through the mitral valve into the left ventricle where it is pushed through the aortic valve and out to the body. The mitral valve differs from the rest of the valves because it is made up of just two flaps; the others have three flaps. The job of the valves is to keep the blood moving all in one direction. ...read more.

you work this out by: Cardiac output = Stroke volume x heart rate Respiratory System The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system's means of getting oxygen to the blood. Respiration is achieved through the mouth, nose, trachea, lungs, and diaphragm. Oxygen enters the respiratory system through the mouth and the nose. The oxygen then passes through the larynx (where speech sounds are produced) and the trachea which is a tube that enters the chest cavity. In the chest cavity, the trachea splits into two smaller tubes called the bronchi. Each bronchus then divides again forming the bronchial tubes. The bronchial tubes lead directly into the lungs where they divide into many smaller tubes which connect to tiny sacs called alveoli. The average adult's lungs contain about 600 million of these spongy, air-filled sacs that are surrounded by capillaries. The inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood. Meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. ...read more.

Conclusion

Hypertrophy would increase causing muscle to grow and reduce the amount of fat in this person's body. Indoor rowing test This test is 2000 meters on level 5 on the rowing machines Time (minutes) Short-Term effects Rating of how the participant feels 1good-10bad 2 Slightly Increased breathing 2/10 4 Arms aching Breathing increased and heart rate 5/10 6 Red faced, sweating Breathing increased and heart rate 7/10 8 Arms Burning Breathing increased and heart rate 9/10 10 Legs Aching, Arms burning Breathing increased and heart rate 10/10 In the 2000 metre rowing test short term effects are red faced, muscle burn and aching, sweat, heavy breathing and increased heart rate. His heavy breathing could have been because the individual may have been struggling for oxygen this is evident because the person began to go red in his face due to a lack of oxygen. Also the muscle burning would support my idea because due to lack of oxygen the muscles where not allowed to get rid of the lactic acid build up. If the individual where to continue doing this exercise for the long term I would expect that this person's cardiovascular endurance would increase and that the individual's heart rate would decrease along with blood pressure. Hypertrophy would increase causing muscle to grow and reduce the amount of fat in this person's body.

    Often, medication can be used to treat abnormal heart beats.42 A medicine used to treat Bradycardia (abnormally slow heart beat, regularly treated with a pacemaker) is Atropine.43 Atropine is used to increase the heart rate44, which therefore increases the amount of blood being pumped around the body.

    Usually, red blood cells will circulate for approximately 120 days in the body until wearing out. It is then that the cells will undergo destruction by the spleen.
