Heart and Blood Flow 1

Label your Heart:

​

In order of Blood Flow- through the valves)

Mnemonic:

T - Toilet .....................T - Tricusped

P - Paper..................... P - Pulmonary

M - My ..........................M - Mitral

A - A ** Hole​ ..............A - Aortic

1. Blood move from the VENA CAVA to the RIGHT ATRIA

2. SA NODE fires- causes ATRIA to contract​

3. ATRIA squeezes blood through the TRICUSPED valve into the right VENTRICLE

4. ELECTRICAL impulse travels from SA NODE - TO THE AV NODE (small delay) then travels through BUNDLES OF HIS - L/R BUNDLE BRANCHES and CONTRACTS the VENTRICLES

5. R. VENTRICLE contract - blood moves the PULMONARY VALVE/PULMONARY ARTERY TO THE LUNGS where it gets oxygenated.

​

6. Oxygenated blood returns via the PULMONARY VEIN TO THE LEFT ATRIA.

7. SA NODES FIRES - causing the ATRIAS to contract - Blood moves from L. ATRIA through the MITRAL VALVE into the LEFT VENTRICLE

8. Electrical impulse travels from SA NODE - AV NODE (small daely) then travels through the BUNDLES OF HIS - L/R BUNDLE BRANCHES and CONTRACTS the VENTRICLES​

​9. L. VENTRICLE contracts - moves blood through the AORTIC VALVE into the AORTA where it then moves to the BODY and returns back to the VENA CAVA (step 1)
