Q

the tough outermost layer of your pericardium. It is made up of connective tissue that prevents your heart from extending too much. It attaches to the great blood vessel on the top of your heart and at the central tendon of the diaphragm at the bottom portion of the heart.

Q

17
Q

Pulmonary Vein contains

A

oxygenated blood

18
Q

It is responsible for receiving blood from the right atrium.

A

RIGHT VENTRICLE

19
Q

It is responsible for receiving blood from the left atrium.

A

LEFT VENTRICLE

20
Q

2 types of heart valves

A

semilunar valves
atrioventricular valves

21
Q

Pulmonary and Aortic Valves are?

A

Semilunar Valves

22
Q

located at the entrance of the pulmonary trunk. It prevents blood from moving from the pulmonary trunk into the right ventricle during ventricular relaxation.

A

Pulmonary Valves

23
Q

It is located at the entrance to the aorta. It prevents blood from moving from the aorta into the left ventricle during ventricular relaxation.

A

Aortic Valves

24
Q

Tricuspid and Bicuspid Valves are?

A

Atrioventricular Valves

25
Q

It is located at the right atrioventricular orifice. It prevents blood from moving from the right ventricle into the right atrium during ventricular contraction.

A

Tricuspid Valve

26
Q

It is located at the left atrioventricular orifice. It prevents blood from moving from the left ventricle into the left atrium during ventricular contraction.

A

Bicuspid Valve (mitral)

27
Q

pathway of blood through the heart

A

1) Blood from systemic circuit
2) Blood will now enter Superior and Inferior Vena Cava,
and Coronary Sinus
3) Blood enters Right Atrium and tricuspid valve will shut
4) Blood enters Right Ventricle and pulmonary valve,
pulmonary trunk and pulmonary arteries which contains
deoxygenated blood
5) Blood enters Pulmonary arteries and will supply blood in
the heart
6) Blood goes to Alveolar capillaries of lungs, where
oxygenation happens
7) Blood will now pass through pulmonary veins containing
oxygenated blood
8) Blood will enter Left Atrium then bicuspid (mitral) valve
will shut
9) Blood will enter Left Ventricle then aortic valve will shut
and then goes to aortic valve and then to aorta
10) Blood will now go to systemic circuit

28
Q

The heart chambers function in coordinated ___________

A

fashion (function?)

29
Q

Atria contracts during _______

A

atrial systole

30
Q

Ventricle relax during _______

A

ventricular diastole

31
Q

Atrial relaxation occurs in ________

A

atrial diastole

32
Q

Ventricular contraction occurs in ________

A

ventricular systole

33
Q

A heart beat through a stethoscope sounds like ________

A

“lubb-dupp”

34
Q

The first heart sound

A

“Lubb”

35
Q

The second heart sound

A

“Dupp”

36
Q

sound that occurs during ventricular systole where AV
valves closes

A

“Lubb”

37
Q

sound that occurs during ventricular diastole where
pulmonary and aortic semilunar valves closes

A

“Dupp”

38
Q

abnormal heart sound from the cusps not completely closing

A

murmur
