What is the primary function of the heart?

• To digest food

• To pump blood throughout the body

• To produce hormones

• To filter waste from the blood

Which layer of the heart wall is responsible for its pumping action?

• Pericardium

• Endocardium

• Myocardium

• Epicardium

How many chambers does the human heart have?

• Two

• Three

• Four

• Five

Which chamber of the heart receives deoxygenated blood from the body?

• Right ventricle

• Left ventricle

• Right atrium

• Left atrium

What is the function of the tricuspid valve?

• To separate the left atrium and left ventricle

• To prevent backflow between the right atrium and right ventricle

• To separate the right ventricle and pulmonary artery

• To prevent backflow between the left ventricle and aorta

Which valve is also known as the bicuspid valve?

• Mitral valve

• Tricuspid valve

• Pulmonary valve

• Aortic valve

What type of blood vessels carry oxygenated blood away from the heart?

• Veins

• Venules

• Capillaries

• Arteries

What is the role of the coronary arteries?

• To remove waste products from the kidneys

• To transport nutrients to the liver

• To supply oxygenated blood to the heart muscle

• To carry deoxygenated blood to the lungs

Which node initiates the electrical impulses in the heart?

• Purkinje fibers

• Bundle of His

• SA node

• AV node

What is the function of the AV node in the heart's conduction system?

• To initiate electrical impulses

• To delay electrical impulses before transmitting to the ventricles

• To coordinate the contraction of the atria

• To distribute impulses to the heart muscle
