Document Summary
Chapter 6 -the cardiovascular system and it"s control. The cardiovascular system serves a number of important functions in the body and supports every other physiological system. The heart is about the size of a st and located in the centre of the thoracic cavity, the heart is the primary pump that circulates blood though the entire cdv system. The heart has two atria that act as receiving chambers and two ventricles that serve as the pumping chambers. It is enclosed in a tour membranous sac called the pericardium. The right side of the heart pumps deoxygenated blood to the lungs through the pulmonary circulation. The left side of the heart pumps oxygenated blood to all tissues through the systemic circulation. Blood that has circulated through the body, delivering oxygen and nutrients and picking up waste products, returns to the heart through the great veins- the superior vena cava and inferior vena cava- to the right atrium.
