ITM blood flow
heart circulation
| Question | Answer |
|---|---|
| arteries | takes blood "away" from heart |
| veins | returns blood "to" heart |
| right & left chambers-atria | "receiving" chambers - |
| 2 lower chambers-ventricles | discharging chambers |
| tricuspid | opening of right atrium into right ventricle |
| bicuspid/mitral valve | opening of left atrium into left ventricle |
| pulmonary semilunar valve | between right ventricle and pulmonary artery |
| aortic semilunar valve | between left ventricle and aorta |
| 1-superior vena cava | "returns deoxygenated" blood from upper part of body to right atria |
| 1-inferior vena cava | "returns deoxygenated" blood from lower part of body to right atria |
| 2-right atria | heart contracts and pushes deoxygenated blood thru the tricuspid valve |
| 3-tricuspid valve | deoxygenated blood pushes into right ventricle |
| 4-right ventricle | deoxygenated blood then moves thru pulmonary semi-lunar valve |
| 5- pulmonary semi-lunar valve | deoxygenated blood then goes into pulmonary arteries |
| 6-pulmonary artery | then takes deoxygenated blood to the lungs |
| 7-lungs | deoxygenated blood exchanges carbon dioxide for oxygen where is is carried by pulmonary veins |
| 8-pulmonary vein | oxygenated blood is carried into left atrium |
| 9-left atrium | heart contracts and pushes oxygenated blood thru bicuspid valve |
| 10-bicuspid valve | pushes oxygenated blood into left ventricle |
| 11-left ventricle | oxygenated blood travels thru aortic semi-lunar valve |
| 12-aorta | then oxygenated blood travels to arterioles |
| 13-arterioles | then oxygenated blood goes to capillaries |
| 14-capillaries | oxygenated blood feeds cells oxygen and takes carbon dioxide, blood is now deoxygenated and must go back to heart so it goes to venules |
| 15-venules | deoxygenated goes to veins |
| 16-veins | deoxygenated blood goes to superior and inferior vena cava |
