Heart Actions: Stroke Essay -- Disease, Disorders

Heart Actions: Stroke The cardiovascular system is mainly to pump blood around the body; it supplies fresh oxygenated blood from the lungs to organs around the body and returns it back again. Arteries supply fresh blood and veins return old blood. By one artery or blood vessel being blocked or damaged the flow of blood to the brain will suddenly stop and result of a stroke. Many consequences will come with a stroke but occupational therapy practitioners make stroke patients lives easier to live with purposeful and innovated interventions. Generally speaking, the force required to circulate blood is given by an engine which is housed almost in the middle of the chest: the heart, which is a pump that operates without stopping for a single second. The function of the heart is pumping blood to all parts of the body. The blood picks up oxygen as it passes through the lungs and travels to the heart to be driven to all parts of the body. After traveling through the body, blood runs out of oxygen and is sent back to the heart to pump it to the lungs to pick up more oxygen. This completes the cycle. To push blood through vessels around the body, the heart contracts and relaxes rhythmically. The contraction phase is called systole, which corresponds to the expulsion of blood outside the cavity. This phase is followed by a phase systolic muscle relaxation called diastole, in which there are two stages: a relaxation and a suction to draw the blood into the interior; and it keeps repeating the same course non-stopping. Following this further, there are countless cardiovascular diseases and cardiovascular syndromes, conditions and diseases are one of the major causes of disability and death in the world believe it or not, but they... ...006; 19: 84-90. - Krug, G., & McCormack, G.
