Which chamber of the heart receives oxygenated blood from the lungs?

Left atrium

Explanation

Receives oxygenated blood from lungs

What is the cardiac output of the heart?

Volume of blood pumped per beat

Explanation

Blood volume pumped per beat

Which blood vessel carries oxygenated blood from the lungs to the heart?

Pulmonary vein

Explanation

Carries oxygenated blood from lungs

What is the term for the volume of blood pumped by each ventricle in one minute?

Cardiac output

Explanation

Blood volume pumped per minute

Which heart valve is located between the left atrium and left ventricle?

Mitral valve

Explanation

Between left atrium and ventricle

What is the function of the heart's valves?

To prevent backflow of blood

Explanation

Prevents blood backflow

What is the term for the contraction phase of the cardiac cycle?

Systole

Explanation

Contraction phase of heart's cycle

Which part of the heart's conduction system delays the electrical impulse to allow the atria to contract before the ventricles?

Atrioventricular (AV) node

Explanation

Delays impulse for atrial contraction

What is the primary function of the pericardium?

To protect and lubricate the heart

Explanation

Heart protection and lubrication

#10

What is the primary function of the atrioventricular (AV) valves in the heart?

To prevent backflow of blood into the atria

Explanation

Prevents blood backflow into atria

#11

Which coronary artery is often referred to as the 'widow-maker'?

Left anterior descending (LAD)

Explanation

Critical coronary artery

#12

What is the function of the sinoatrial (SA) node in the heart?

Conduction of electrical impulses

Explanation

Conducts heart's electrical impulses

#13

Which of the following factors can contribute to the development of atherosclerosis?

High levels of LDL cholesterol

Explanation

High LDL cholesterol contributes

#14

What is the term for the relaxation phase of the cardiac cycle?

Diastole

Explanation

Relaxation phase of heart's cycle

#15

What is the role of the sympathetic nervous system in cardiac physiology?

Increasing heart rate and contractility

Explanation

Increases heart rate and contractility
