Hint: both atria….and ventricles
The atrial contracts(systole) and ventricle relaxes(diastole). Then atrial relaxes(diastole) and ventricles contracts(systole)
a recording of electrical changes in the myocardium during the cardiac cycle
What is this machine called?
Electrocardiogram
or aka ECG
P wave is what type of polarization which results in what type of movement?
ATRISL DEpolarization aka resulting in atrial CONTRACTION
QRS complex is what type of of polarization, causing what type of action?
Depolarization all throughout, this is done before the CONTRACTION of BOTH ventricles as the atria is going into relaxation mode

Describe the breakdown of RBC
Shit RBC—> SPLEEN or LIVER(removal) –more brakedown–>HEMOGLOBIN —–more—-> GLObin Chains(AHA HEME)—-> iron &/or biliVERDIN—–>bill => biliRUBIN
Describe how RBC is broken down
- Old RBC is damaged by going through blood vessels
- Spleen & Liver detects this and phagocytize RBC
- Breks into Heme & Globin
- Globin turns into Amini Acid but also can be reabsorbed by plasma or eaten my macrophages
- Heme turn into iron & some into biliverdin
-Iron is reused for creating of more hemoglobins
-Biliverdin turns to bilirubin…/verdin and this is can be used to be secreted by bile and give bile pigment. RUBIN goes into KIDNEY
