14
Q

what artery carries deoxygenated blood

A

pulmonary artery

15
Q

what vein carries oxygenated blood

A

pulmonary vein

16
Q

Where is the tricuspid valve located and what is another name for it?

A

Between the right atrium and right ventricle, right atrioventricular valve.

17
Q

Between what two layers of the heart is there a fluid filled space and what is its purpose?

A

Visceral and parietal layers. The fluid acts as a lubricant to allow smooth expansion and contraction.

18
Q

In what cardiac cycle does the heart relax and refill with blood to be ejected during the next systolic contraction?

A

Diastole

18
Q

What is the difference between Sinus bradycardia and Sinus tachycardia?

A

Sinus bradycardia Abnormally slow heart rate Normal conductivity Sinus tachycardia Abnormally fast heart rate Normal conductivity

19
Q

In what cardiac cycle does the heart muscle contract, eject blood from the atria to the ventricles, and then from the ventricles to the arteries?

A

Systole

21
Q

What keeps the valve between the atrium and the ventricle from bending back into the atrium

A

Chordae tendineae

22
Q

oval opening that alows blood to by pass the fetus’s lungs

A

Foramen ovale

23
Q

What is the caudal bend of the heart

A

The Apex

24
Q

Instrument that is used to measure electrical activity of the heart

A

Electrocardiogram

25
Q

Normal feline Heart Rate

A

150-210bpm

27
Q

Normal Canine Heart Rate

A

70-160 bpm

28
Q

Where is the mitral valve located and what is another name for it?

A

Between the left atrium and left ventricle, left atrioventricular valve.

29
Q

Pulse Deficit

A

When the heart rate and pluse rate are not the same

30
Q

Normal Feline Heart Rate

A

150-210 bpm

32
Q

The vein most commonly used for venipuncture is the____vein?

A

Jugular

33
Q

What 2 factors control cardiac output?

A

Stroke Volume and Heart Rate

35
Q

what are the 3 things we can change to manage heart disease?

A

Pump - strength of the beat, Pipes - constrictict or dilate vessels, Fluid - viscosity

36
Q

What is the electrical anatomy of the heart?

A

SA Node, AV Node, Bundle of His, Purkinje Fibers

37
Q

What does the T wave represent?

A

relaxing of the ventricle and recharging of the node

38
Q

What is the outer layer of the heart called?

A

Pericardium

39
Q

What is the order of blood flow?

A

Vena cava

Right Atrium

Tricuspid valve

Right ventricle

Pulmonary valve

Pulmonary artery

Lungs

Pulmonary vein

Left atrium

Mitral valve

left ventricle

aortic valve

aorta

Systemic circulation

40
Q

The chordae tendineae connect to the _______ muscles

A

Papillary

41
Q

What does SA node stand for?

A

Sinoatrial node

42
Q

the mitral valve separates what 2 chambers of the heart

A
