| Circulatroy System/Cardiovascular System: | -system consisting of heart, blood vessels, & blood circulating through body. |
| 4 key elements of circulatory system: | -transports and delivers oxygen and nutrients.
-transports and delievers chemical messengers throughout body (ex.hormones)
-distributes body heat
-defends against disease |
| cardiovascular= cardio+vascular: | cardio=heart
vascular=blood vessels and blood |
| oxygenated or deoxygenated? Superior Vena Cava | Deoxygenated |
| oxygenated or deoxygenated? Pulmonary Artery | Deoxygenated |
| oxygenated or deoxygenated? Pulmonary Veins | Oxygenated |
| oxygenated or deoxygenated?Inferior Vena Cava | Deoxygenated |
| oxygenated or deoxygenated? Right Atrium | Deoxygenated |
| oxygenated or deoxygenated? Right Ventricle | Deoxygenated |
| oxygenated or deoxygenated? left ventricle | oxygenated |
| oxygenated or deoxygenated? left atrium | oxygenated |
| oxygenated or deoxygenated? aorta | oxygenated |
| septum: | a thick wall of muscle that divides the left and right sides of the heart |
| atrium: | the smaller upper chamber that recieves blood returning to the heart. |
| ventricle: | the larger v-shaped bottom chamber that pumps blood from the heart. |
| heart valves: | thin flaps of tissue in the heart that open and close to ensure the proper direction for blood flow. |
| diastole: | the phase of the heart's cycle where a chamber of the heart(atrium or ventricle), relaxes and fills with blood. |
| systole: | the phase of the heart's cycle when the ventricles contract to eject blood from within the chamber> |
| "Lubb" "Dubb" | (1)Lubb: AV Valves close
(2)Dubb: AV Valves open |
