Relaxation of the heart

30
Q

What are heart actions?

A
31
Q

Sequence of myocardial contraction and relaxation that constitutes a complete heartbeat.
What type of cycle is this?

A

Cardiac Cycle

32
Q

Describe how the Cardiac Cycle goes
Hint: Atria contracts and…

A

Atrial(aka atrium) Systole(aka contracts) AND Ventricular Diastole(aka relaxes)
vise versa
Ventricular Systole and Atrial Diastole

33

CARDIAC CONDUCTION SYSTEM

35
Q

THE _______ is a pacemaker because it initiates heart rhythmic contractionsaka heartbeat

A

Sinoatrial Node
SA

36

37
Q

What is Bundle Branch Block?

A

When the purkinje fibers FAILS to contract and relax leading for blood to go do sum kick backing shi

38
Q

Describe a series of events that happen to conduct a single heart beat
Hint: both atria….and ventricles

A

The atrial contracts(systole) and ventricle relaxes(diastole). Then atrial relaxes(diastole) and ventricles contracts(systole)

39
Q

a recording of electrical changes in the myocardium during the cardiac cycle
What is this machine called?

A

Electrocardiogram
or aka ECG

40
Q

P wave is what type of polarization which results in what type of movement?

A

ATRISL DEpolarization aka resulting in atrial CONTRACTION

41
Q

QRS complex is what type of of polarization, causing what type of action?

A

Depolarization all throughout, this is done before the CONTRACTION of BOTH ventricles as the atria is going into relaxation mode

42
Q

substances diffuse through membrane channels and slits
What type of capillary exchange is this?

A

Diffusion

55
