17
Q

what is the foramen ovale?

A

hole between right and left atrium

18
Q

what is the ductus arteriosus?

A

allows blood to pass from pulmonary trunk to aorta around the body

19
Q

why do the foramen ovale and ductus arteriosus shut when a baby cries?

A

because air is rushing into the lungs and the pressure is massively increasing

20
Q

why are coronary arteries described as end arteries?

A

they supply one specific tissue and if the artery is blocked the tissue dies

21
Q

when the foramen ovale shuts what does it become?

A

the fossa ovalis

22
Q

what is the orifice of coronary sinus?

A

the venous drainage of the heart

23
Q

what does the musculi pectinati do?

A

increases the blood flow in the heart

24
Q

what are the chordae tendindae?

A

heart strings which are joined onto capillary muscles and ensure the blood doesnt go in the opposite way in the heart

25
Q

why is the left ventricle thicker?

A

it needs to pump blood through the entire body

26
Q

what does a ventricular septal defect cause?

A

a mixing of blood

27
Q

what does an atrioventricular septal defect mean?

A

blood goes everywhere between atria and ventricles and cardiac surgery is needed straight away due to the mixing of blood

28
Q

what causes an atrioventricular septal defect?

A

incomplete closure of the foramen ovale

29
Q

what are the 4 heart valves called?

A

pulmonary semilunar valve, aortic semilunar valve, bicuspid valve and tricuspid valve

30
Q

what does the LUB sound of the heart indicate?

A

loud noise due to closure of atrioventricular valves at the time of ventricular systole

31
Q

what does the DUB sound of the heart indicate?

A

softer sound due to closure of the semilunar valves at the time of atrial systole

32
Q

what is atrial fibrillation?

A

rapid, irregular contraction of different parts of the atria

33
Q

what is ventricular fibrillation?

A

rapid, irregular contraction of the ventricles

34
Q

what does systole cause?

A

expansion of arterial walls

35
Q

what is arterial flow regulated by?

A

varying diameter of capillaries

36
Q

what are the 3 layers of the heart?

A

tunica intima, tunica media, tunica adventitia

37
Q

where is the tunica intima?

A

direct contact with blood

38
Q

what is the tunica media?

A

elastic fibres, and smooth muscle fibres

39
Q

where is the tunica adventitia?

A

supporting tissue on outer side

40
Q

what arteries are elastic?

A

aorta, common carotid, subclavian and pulmonary arteries

41
Q

what arteries are muscular?

A

radial, femoral, coronary, cerebral

42
Q

what are arterioles?

A

terminal branches supplying capillary bed
