Cardiovascular response to changes in body position and physical activity Abstract The aims of the experiment were to investigate the cardiovascular responses to changes in body position and exercise on human blood pressure using an electronic (automated) blood pressure meter. Moreover‚ monitoring changes in blood flow and blood pressure in the body while sitting‚ lying supine‚ standing‚ as well as engaging in low intensity exercise of walking and medium intensity exercise of squatting after

CARDIOVASCULAR SYSTEM OF THE HEAD NECK The cardiovascular system consists of the heart‚ blood vessels‚ and the approximately 5 liters of blood that the blood vessels transport. Responsible for transporting oxygen‚ nutrients‚ hormones‚ and cellular waste products throughout the body‚ the cardiovascular system is powered by the body’s hardest-working organ — the heart‚ which is only about the size of a closed fist. Even at rest‚ the average heart easily pumps over 5 liters of blood throughout

The Cardiovascular System The cardiovascular system consists of a heart and an enclosed system of blood vessels categories into arteries‚ capillaries and veins. The heart is a muscle about the size of the fist; its wall is made up of a muscle known as the Cardiac Muscle‚ and is located between the two lungs and lies left of the middle of the chest (cliff notes). A fibrous covering known as the pericardium which surrounds around the whole heart holds the heart in place but allows it to move as

Cardiovascular fitness is the practice of utilizing and transporting oxygen in the process using your heart lung and organs. The practice of this can improve the pumping of the blood and oxygen to the body making it more efficient and easier to release oxygen therefore improving your exercising techniques. An important fact about cardiovascular fitness is the maximum volume of oxygen you body can retain is VO2 Max. There are many forms of exercising and practicing cardiovascular fitness. Some examples

Body Systems Cardiovascular System - relates to the heart‚ blood vessels and circulation in the body. The cardiovascular system‚ also known as the circulatory system‚ refers to the network that transports blood throughout the body. It is composed of the heart‚ blood vessels‚ and blood. There are actually two circulatory systems: * The pulmonary circulation – sends blood from the heart to the lungs. * The systemic circulation – sends blood from the heart to all the other parts of our
