Introduction

Anatomy Assignment 3 Cardiovascular and Respiratory System Cardiovascular System Introduction: The Heart is made up of a powerful muscle called Myocardium. The Myocardium is composed of cardiac muscle fibbers that contracts and causes a wringing type of action. The size of you heart is a little larger than the size of your fist. The location of the heart is about left-centre of your chest. The heart is two separate pumps that continuously send blood throughout the body carrying nutrients, oxygen, and helping remove harmful wastes. The right side of the heart receives blood low in oxygen. The left side of the heart receives blood that has been oxygenated by the lungs. The blood is then pumped out into the Aorta and to all parts of the body. Many people say that Arteries carry oxygenated blood and the Venues carry deoxygenated but there is and exception for each Pulmonary Vein is the other exception as it carries oxygenated blood so its fare to say that Venues carry blood to the heart and the Arteries carry blood around the body. The Heart Diagram above and the information that follows will give a better understanding of the heart structure and how the blood circulates through the heart. ...read more.

The Aorta carries oxygenated blood to every other part of the body. The Aorta receives its blood from the Left Ventricle. It needs to be big so that it can give the amount of pressure to push the blood around the body and to the brain. Superior Vena Cava: The importance of the Superior Vena Cava is to return blood back to the Right Atrium from the upper part of the body. It is one of the largest veins in the body. Inferior Vena Cava: The Inferior Vena Cava is important for carrying the blood back to the Right Atrium from the lower part of the body. Pulmonary Arteries: The Pulmonary Arteries carry the blood from the Right Ventricle to both of the lungs. There the blood is oxygenated and sent to the Left Atrium in the heart. This is the only Artery that pumps deoxygenated blood to any place in the body. Pulmonary Veins: The Pulmonary Vein carries the oxygenated blood back to the Left Atrium in the heart. This is the only vein that carries oxygenated blood to any place in the body. Respiratory System This system links up with cardiovascular system by the fact that cardiovascular system takes blood around the body and respiratory system is the oxygen that the blood travels with the blood or carbon dioxide. ...read more.

Conclusion

The respiratory system consists of > Nasal cavity > Pharynx > Epiglottis > Larynx > Trachea > Bronchus > Bronchioles > Alveoli Each one of these contributes to the respiratory system to sustain life, as we know it. If one of theses weren't working or doing its job a good as it could you could die. These are all important in sport, as there is a lot of running about going on in most sports. * Nasal cavity is where the gasses enter the body and travel down the body. * The Trachea splits into two tubes called Bronchi one going to each lung. * The bronchi splint into progressively smaller tubes called Bronchioles. * Alveoli- air sacs in the lungs in which gaseous exchange takes place. The air breathed in and out of the body consists mainly on 3 gasses in a health person. * Oxygen the main sores of how we sustain life it only takes up 21% of the air breathed in and out is 16%. * Carbon dioxide, which consists of 2-part oxygen, is 0.04% in and 4% out of the body. * Nitrogen is the highest gas as in there is more of nitrogen takes up the last of the percentages 78% in and out of the body so its not use or at least it re-accumulates in the body to give the same percentage.

    Urea and water are filtered through the kidneys and expelled from the body. Carbon dioxide is carried in the blood to the lungs, where it passes into the alveoli and is then expelled from the body. Blood lactate accumulation, carbon dioxide and increased acidity Raised levels of carbon dioxide increase (from exercise)

    The performer then crouches, leans forward, swung their arms backwards and jumped horizontally as far as possible with both feet. The distance jumped is then the final result. All these fitness tests were done before and after the six week exercise program to allow comparison between each test attempt to be made.

    This means that after continual muscle contraction, the muscles will loose force. When it is difficult or impossible to contract the muscles, then this is termed muscle exhaustion. The short-term effects of anaerobic respiration on the muscles are fatigue after a short while, some pain and an oxygen debt.

    The synovial fluid lubricates the joint. * In addition to the capsule, the bones are also attached and held together by strong, tough ligaments made of dense connective tissue. These ligaments prevent dislocation during normal movement. * The articulating surfaces of adjacent bones are reciprocally shaped.

    The ribs are part of the axial skeleton and there are 12 pairs in total these are flat bones, which are made to protect the organs within. Some of the bones that are found in the appendicular skeleton are the scapulae's that are flat bones and the clavicles that are short bones and these two bones make up your collarbones.

    For example, the mean of the following sets of data are the same: 15, 15, 15, 14, 16 and 2, 7, 14, 22, 30. However, based from those statistics, it is clear the second set is more spread out. If a set has a low standard deviation, the values are not spread out too much.
