What is septicemia sepsis?

• A condition caused by the spread of microorganisms and their toxins via the circulating blood

• A rapid heartbeat that begins within the ventricles

• The surgical removal of plaque buildup from the interior of an artery

• A muscle that divides the left and right side of the heart

What is the function of the septum in the heart?

• Causes blood vessels to narrow

• Divides the left and right side of the heart

• Forms a low-pressure collecting system

• Causes blood vessels to expand

When does systolic pressure occur?

• When the ventricles relax

• When the atria contract

• When the ventricles contract

• When the heart rate slows

What is tachycardia?

• Slow heart rate

• Fast heart rate

• Irregular heart rhythm

• Heart muscle inflammation

What does a vasoconstrictor do?

• Causes blood vessels to expand

• Causes blood vessels to narrow

• Increases heart rate

• Decreases blood pressure

What is the role of a vasodilator?

• Causes blood vessels to narrow

• Causes blood vessels to expand

• Increases blood clotting

• Decreases heart rate

What is the function of veins?

• Carry oxygen-rich blood to the heart

• Form a low-pressure collecting system to return oxygen-poor blood to the heart

• Pump blood out of the heart

• Store blood cells

What are ventricles?

• The two upper chambers of the heart

• The two lower chambers of the heart

• The muscles that divide the heart

• The valves in the heart

What is ventricular fibrillation?

• A slow, regular heartbeat

• The rapid, irregular, and useless contractions of the ventricles

• The accumulation of plaque

• The narrowing of arteries

What is ventricular tachycardia?
