• Arterioles, Venules, Ducts

• Aorta, Vena cava, Capillaries

• Arteries, Veins, Bile ducts

Which blood vessels carry blood away from the heart?

• Venules

• Arteries

• Capillaries

• Veins

What is the primary function of capillaries?

• Pump blood

• Hold blood

• Exchange of gases and nutrients

• Direct blood flow

Which chamber of the heart is responsible for pumping oxygenated blood to the body?

• Right Ventricle

• Right Atrium

• Left Atrium

• Left Ventricle

What type of valve is located between the left atrium and the left ventricle?

• Bicuspid Valve

• Tricuspid Valve

• Pulmonary Valve

• Semilunar Valve

What is the effect of the valves in the heart?

• They increase blood pressure

• They decrease heart rate

• They prevent backflow of blood

• They oxygenate the blood

What happens when the left ventricle contracts?

• It receives blood from the body

• It sends blood to the body

• It receives blood from the lungs

• It sends blood to the lungs

What is the role of the SA node in the heart?

• It closes the heart valves

• It initiates the heartbeat

• It relaxes the atria

• It contracts the ventricles

What does an EKG measure?

• Heartbeat initiation

• Blood pressure

• Oxygen levels in blood

• Electrical activity of the heart

Which condition requires the use of a defibrillator?

• Low heart rate

• High blood pressure

• Heart arrhythmia

• Fibrillation
