HOW THE HEART WORKS
Transcript of HOW THE HEART WORKS
The upper portion is the atrium
The lower portion is the ventricle
Both portions are divided into two parts Healthy Blood Pressure Diastolic with a range of >80 Average Blood Pressure: 119/79 Systolic with a range of >120 As the heart beats, it pumps blood through blood vessels (circulatory system) Blood carries oxygen from the lungs and nutrients to the body's tissues, and takes away the wastes. This maintains a healthy body. Veins - Blood vessels that take blood back to the heart. Arteries - Start with the aorta, the large artery leaving the heart. Arteries carry blood with oxygen away from the heart to all of the body's tissues. Capillaries - Blood vessels that connect the arteries and the veins. They allow oxygen, nutrients, carbon dioxide, and other waste products to pass to and from our organ's cells.
Right Side of the Heart
Blood enters the heart through two large veins, the inferior and superior vena cava, and gets rid of blood with poor oxygen through the right atrium of the heart. When the ventricle is full, the mitral valve shuts. This prevents blood from flowing backward into the atrium when the it contracts. The pulmonary vein empties oxygen-rich blood from the lungs into the left atrium of the heart. Left Side of the Heart
