Valves
What are the 2 TYPES of valves?
AV and Semi Lunar valves
The heart provides the body with __________ and _____________ and removes ___________
oxygen, nutrients, metabolic waste
The heart's own blood system is known as what?
Coronary Circulation
The atria are known as what kind of chambers?
Receiving chambers
This initiates atrial depolarization and produces a "p" wave
Mitral valve
The cells are responsible for the contraction and relaxation of the heart
myocardial cells
The 2 main blood vessels that supply the heart with the blood are
LMCA (left main coronary artery) and RCA (Right Coronary Artery)
The primary pumping chambers of the heart
Ventricules
This waveform represents ventricular repolarization
T-wave
The AV valve that separates the right atrium and left ventricule is known as what?
Tricuspid valve
These are the cells responsible for creating and conducting the electrical impulse throughout the heart
pacemaker cells
In order of blood flow name the four chambers
Right atrium, right ventricle, left atrium, left ventricle
Chamber that has the most myocardium (largest chamber)?
Left ventricule
This structure receives the signal from the AV node and relays it to the bundle branches.
Bundle of His
how many leaflets do the semilunar valves have?
3
the electrocardiograph represents what type of activity of the heart
A. mechanical
B. Structural
C. Electrical
D. Pathological
C Electrical
In order of blood flow list the 4 valves
Tricuspid, pulmonic, bicuspid, aortic
Which atrium receives de-oxygenated blood
right atrium
Delays the signal coming from the SA node long enough to allow complete contraction of the atria
AV Node
Pulmonic and Aortic
The ability of a cell to spontaneously generate an electrical impulse
automaticity
Large blood vessels that deposit deoxygenated blood into the right atrium
Superior and inferior vena cava
which atrium receives oxygenated blood
left atrium
Receives the signal from the bundle branches and relays it to the cells of the ventricules
Purkinji fibers/network
