Identify this pointy part of the sheep heart.
apex
interventricular sulcus

How do the atrial walls compare to the ventricular walls?
atrial walls are thicker than ventricular walls
atrial walls are thinner than ventriclular walls
atrial walls are red, ventriclular walls are blue
atrial walls are bigger than ventriclular walls
What is the purpose of the heart valves?
to allow blood to flow in only one direction through the heart
to allow blood to flow back and forth between chambers
to create blood pressure
to make the lub dup sound
Which artery is the largest and why?
The vena cava is the largest artery because it carries all the body's blood back to the heart
The Pulmonary artery is the largest because it carries all the blood to the lungs
The Aorta is the largest because it carries all the blood out into the body and has to withstand the most force
Which side of the heart contains DE-OXYGENATED blood?
Left Side
Right Side
Superior
Inferior
Why are the artery walls thicker than vein walls?
arteries hold more blood than veins
arteries are more likely to get disease than veins
arteries are made of different material than veins
arteries have to withstand a higher blood pressure than veins
The thick muscular wall that separates the left and right ventricles is...
the aorta
the interventricular septum
the chordae tendinae
