Flashcards in Functional Anatomy Of The Heart Deck (15):
1

What is the pericardial sac

Similar to pleural cavity
Between pericardium and epicardium and contains pericardial fluid

2

What fully encapsulates allof the heart

Fibrous pericardium

3

What are the great vessels associated with the heart

Superior and inferior vena cava
Aorta
Pulmonary trunk (left and right pulmonary arteries )

4

What are the surfaces of the heart

Apex
Anterior
Posterior
Inferior

5

What is a myocardial infarction

Heart attack
Irreversible necrosis of part of the heart due to blockage of arterial supply
Type either anterior or inferior

6

What supplies the heart with its own arterial supply

Contrary arteries left and right come off of ascendin aorta

7

What is the venous drainage of the heart

Through the coronary sinus which drains into the right atrium

8

What side pumps what type of blood

Right pumps venous and left pumps arterial

9

What separates the two sides of the heart

Septum

10

What are the two kinds of chambers

Atria and ventricles

11

What is the sequences of valves in the heart

From the right atrium to the aorta goes
Tricuspid --> pulmonary --> mitral/bicuspid --> aortic

12

What is the anatomy of a valve

Can be differnt cuspid tri or bicuspid
Pulled by chordinae tendinae
Which are attached to papillary muscles

13

How dos the heart conduct a heartbeat

Sinoatrial node in right atrium is the pacemaker
Atriventriclular us back yo and passes on electrical impulse to bundle of His then to right and left bundles to purkinje fibres spreading the impulse through the walls of the ventricles

14

How does the heart generate a lub dub sound

Lub - first heart sound form closure of tricuspid and bicuspid valves
Dub - second heart sound form closure of pulmonary and aortic valves

15

What layer surrounds the heart

Epicardium which secretes pericardial fluid
