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

Cardiovascular system: The circulatory system: The circulatory system is made up of the vessels and the muscles that help and control the flow of the blood around the body. This process is called circulation. The main parts of the system are the heart‚ arteries‚ capillaries and veins. As blood begins to circulate‚ it leaves the heart from the left ventricle and goes into the aorta. The aorta is the largest artery in the body. The blood leaving the aorta is full of oxygen. This is important for

The Cardiovascular System The heart is one the primary organs in our body. The cardiovascular (CV) system is made up of the heart‚ the blood and the vessels through which blood travels. The CV system works in sequence with the respiratory system to maintain homeostasis. The heart acts as a pump which move the blood through the blood vessels to the tissues and organs of the body. This allows the CV system to help maintain homeostasis by enabling it to carry out its four major functions

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

HYPERTENSION‚also known as high blood pressure‚ is the most common chronic cardiovascular disease in which the blood vessels (arteries) have persistently raised pressure. Blood pressure is the force of blood exerting against the walls of arteries as it is pumped by the heart through out the body. Therefore‚ hypertension occurs when the blood is pushes harder against the arterial wall. It is called the “SILENT KILLER" because it shows no signs and symptoms that is why it is important to check

The cardiovascular system is an organ system comprised of the heart‚ blood and blood vessels. The cardiovascular system forms a part of the circulatory system‚ which circulates blood‚ lymph and oxygen throughout the body. The cardiovascular system works in conjunction with the digestive system to move nutrients throughout the body‚ and is also closely related to nervous system function. Here are some facts and functions of the cardiovascular system. 1. The Heart is at the Center of the Cardiovascular
