Layers of the heart wall superficial to deep

Epicardium → myocardium → endocardium

The fibrous cardiac skeleton of the heart

Myocardium

Made of simple squamous epithelium

Endocardium

Layer of the heart infiltrated with fat

Epicardium

This layer of the heart is a nonconductor

Myocardium

Anchor cusps of AV valves to papillary muscles to hold flaps closed

Chordae tendinae

Anastomoses

Provide collateral routes to ensure blood flow to the heart

Why are anastomoses important?

They ensure the heart receives blood even if major vessels are blocked

Baroreceptors monitor

Changes in blood pressure

Tachycardia

Persistent resting heart rate above 100bpm

Bradycardia

Persistent resting heart rate below 60bpm

Connects pulmonary trunk to aorta

Ductus arteriosus

Opening that connects atria

Foramen ovale

The ductus arteriosus becomes the ___ in adulthood

Ligamentum arteriosum

The foramen ovale becomes the ___ in adulthood

Fossa ovalis

Both ventricles must eject the same amount of blood

True

A myocardial infarction is a

Heart attack

What is angina pectoris?

Temporary ischemia (reduced blood flow)

What causes a myocardial infarction?

Prolonged ischemia

The heart repumping the same blood repeatedly due to backflow happens because of

Valvular prolapse

___ prevent AV valve flaps from everting back into the atria

Chordae tendineae

Trabeculae carnea

Muscles on the ventricle wall

Anchor the chordae tendinae

Papillary muscles

Mark right atrial wall and auricles

Pectinate muscles

Too much fluid leaks into pericardial cavity, compressing the heart and limiting pumping ability

Cardiac tamponade

Refers to all events associated with blood flow through the heart during one complete heartbeat

Cardiac cycle

End diastolic volume (EDV)

Volume of blood in each ventricle at end of ventricular diastole

What is the average EDV?

120ml

End systolic volume (ESV)

Volume of blood remaining in each ventricle after systole

Stroke volume (SV)

Amount of blood ejected

Average stroke volume (SV)

70 ml

Ejection fraction

SV / EDV

Cardiac output (CO) is the volume of blood pumped by each ___ in one minute

Ventricle

Cardiac output calculation

HR X SV

Difference between resting and maximal cardiac output

Cardiac reserve

The pacemaker of the heart

Sinoatrial node

Depolarization of S.A node and atria

P wave

Ventricular depolarization

QRS complex

Ventricular repolarization

T wave

Located between atria and ventricles

Atrioventricular valves

Located between ventricles and major arteries

Semilunar valves

Valves open due to a buildup of

Pressure
