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 |
