Gross Anatomy of the heart

Which side is thicker the left or the right

Left

The actual muscle of the heart is called the

Myocardium

The Epicardium has blank thick in some places

Adipose

Coronary blood vessels that feed your myocardium travel through this layer

Epicardium

Smooth inner lining of heart and blood vessels

Endocardium

Cover the valve surfaces is continuous with endothelium of blood vessels

Endocardium

The myocardium is the blank muscle

Cardiac

Which side has more muscle

left

What formation is the Myocardium in around your heart

Spiral

The spiral formation causes your heart what when it contracts

twists

Myocardium is attached to a

Fibrous skeleton

Provides structural support and attachment for muscle and valves

fibrous skeleton

Electrical insulation between atria and ventricles

fibrous skeleton

Two chambers at the top

Atria

Two chambers at the bottom

Ventricles

Blood enters the heart here

Atria

Each of the atrium has an

Auricle

Extension of the atrium to enlarge the chamber

Auricle

Internal ridged of atria and auricles

Pectinate muscles

Which veins empty into the right atria

Inferior & Superior venae cavae

Which veins empty into the left atria

Pulmonary veins

Discharging chambers of the heart

ventricles

Internal ridges in both ventricles

Trabeculae carneae

The ridges that prevent your heart from sticking together

Trabeculae carneae

Which veins empty out of the right ventricle

Pulmonary trunk

Which veins empty out of the left ventricle

Aorta

Grooves that separates atria and ventricles

Atrioventricular sulcus

What you see in these grooves are going to be your coronary arteries

Atrioventricular sulcus

Overlies interventricular septum that divides the right ventricle from the left

Interventricular sulcus

What side of the atrium has O2

What side of the atrium doesn’t have O2
