What is the term for the membranes surrounding the heart

• Pericardium

• eipdermis

• connective tissue

• heart wall

What is the main component that makes up the heart wall? It consists mainly of cardiac muscle cells (myocytes) as well as pacemaker cells and CT.

• Endocardium

• Epicardium

• Myocardium

• Pericardium

How many chambers are in the heart, and what are the names?

• 2

  Ventricles

  Atria

• 1

  Ventricles

  Atria

• 3

  Ventricles

  Atria

• 4

  Ventricles

  Atria

Which circuit delivers deoxygenated blood to the right side of the heart

• Pulmonary circuit

• Systemic circuit

What side of the heart carries oxygenated blood

• Right

• Left

What are the major systemic veins of the hear

• Sup/Inf Vena Cava

• Cardiac vein

• Pulmonary trunk

• Aorta

Which are larger between the atria and ventricles and why

• Atria --> because they have much stronger pumps

• Ventricles --> because they have much stronger pumps

• Atria --> Because they have thicker walls

• Ventricles --> because they have thinner walls

What are the ventricles separated by

• Supra ventricular septum

• Middle ventricular septum

• Intraventricular septum

• Ventricular septum

What are the names of the Atrioventricular (AV) valves

• Tricuspid

• Aortic

• Pulmonary

• Bicuspid

Where are the AV valves located (select all that apply)

• Tricuspid --> between right atrium and right ventricle

• Bicuspid --> Between right atrium and right ventricle

• Tricuspid --> between left atrium and left ventricle

• Bicuspid --> between left atrium and left ventricle
