When the blood circulates within our system‚ chemicals are exchanged by diffusion. Our cardiovascular system is made up of our heart‚ arteries and our veins. There is an important difference between the veins and the arteries. That difference is the flow or direction of the blood. Veins carry blood to the heart and arteries carry blood away from

Physiology plays a major role in the way the body functions. In football the body has to adapt to the intensity of the game as it varies from low to high. A footballer would mainly use their aerobic energy system due to constant and consistent exercise. It is suggested that footballers use 90% of their aerobic metabolism (Mcmillan et al 2004). Yet they would also use their anaerobic energy when displaying skills such as striking as it uses a short burst of energy. The aerobic capacity of a footballer

Cardiovascular System Anatomy & Physiology The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body. It is a four-chamber pump‚ with the right side receiving deoxygenated blood from the body at low presure and pumping it to the lungs (the pulmonary circulation) and the left side receiving oxygenated blood from the lungs and pumping it at high pressure around the body (the systemic circulation). The myocardium (cardiac

This experiment‚ Cardiovascular Fitness‚ produced the results of the fitness and fitness index of an athlete versus a non- athlete. To do so both the athlete and non-athlete had to preform the step test in which they stepped up and down the stairs at the same pace for the same duration of time. The hypothesis made by my group was that the athlete would have a lower heart-rate and better fitness index then the non-athlete. We guessed this base on the fact that many youth in America who aren’t athletes

The body system that most interests me is the cardiovascular system‚ I chose this system because I’m fascinated with how the heart works and how the blood flows throughout our whole body. The heart is a muscle that contracts which allows blood to be pushed throughout the body. The heart provides many nutrients and blood to the whole body along with many vital organs. The heart is spilt into four chambers: the right atrium‚ left atrium‚ left ventricle‚ and right ventricle. The blood flow starts in

What is Exercise Physiology? Exercise physiology is a scientific discipline that focuses on how an organism responds to exercise. Exercise represents one of the greatest stresses that an organism can encounter. Therefore exercise represents an outstanding model for studying human and animal physiology. Most people are familiar with the study of exercise physiology as it relates to sport performance. However‚ in the last several decades it has become apparent that the study of exercise

The cardiovascular system is made up of the heart and blood vessels‚ which are divided into arteries‚ veins and capillaries. The blood delivers nutrients and oxygen to the cells in the body. The arteries carry blood away from the heart and the veins carry it back to the heart. Capillaries are found in the muscles and the lungs‚ they have valves to stop the blood flowing backwards and this is also where gaseous exchange takes place. The heart works as a pump that pushes blood to the organs‚ tissues
