A heart valve that does not close properly causes this problem | A heart murmer |
What makes the lub dub sound... | The closing of the AV and than semi-lunar valves |
Where does the heart beat orrigionate? | SA node or pacemaker |
Who resists the heart beat so that the ventricals can fill before they contract? | AV Node |
From the AV node where does the signal travel? | Down the bundle of His to the Purkinji fibers |
What are the two pericardiums of the heart? | Parietal and Visceral Pericardium |

EKG/ ECG | Electro cardiogram |
Heart ultrasound | sound immage of the heart |
Stress Test | Measures with EKG how well your heart is performing in varous situations |
How does blood clot? | Platelets and fibrin form clot, blood vessels spasm, coagulation of blood |
What is a thrombus | Blood clot in an unbrocken blood vessel |
What is an embolus | Moving blood clot |

Who can recieve blood from type 0- | Everyone. It is the universal donar |
Who can recieve blood from everyone? | AB+ (Has all the blood markers/ antigens |
Why must an Rh- mother be carefull? | If the baby is Rh+ she could form antibodies agaisnt it and kill the baby |
Which type of blood cell begins the immune reaction? | Macrophage when it eats the pathogen and displays part of its antigen on the Class II MHC recptor |
What do helper T cells do? | They check Macrophages and B cells Class II MHC receptors for antigen presentation. If they are the same they stimulate B cells to divide. They do not kill |
What do B cells do once activated by helper T cells? | They form Memory cells and cells that make antibodies. |
What do antibodies do? | Hold on to antigens so that other T-cells can destroy them. |
