Q

Describe the pericardium.

A

Q

What causes the lub dub sounds produced by the heart?

A

Lub: S1, closing of AV valves

Dub: S2, closing of the SL valves

17
Q

What is the cardiac conduction system?

A

Modified cardiac myocytes
Specialized tissue hat stimulates contraction
Heart does not need external stimuli to contract

18
Q

What does an EKG measure?

A

Action potential traveling though the conduction system
Contraction of the cardiac muscles
Diagnoses cardiac diseases

19
Q

What is associated with left heart failure?

A

Pulmonary edema

20
Q

What is associated with Right heart failure?

A

Peripheral edema
