Which chamber of the heart receives deoxygenated blood from the systemic circulation?
Left atrium
Left ventricle
Right ventricle
Right atrium
The right atrium is the initial chamber for systemic venous return, receiving deoxygenated blood via the superior and inferior venae cavae. This blood then flows through the tricuspid valve into the right ventricle for pulmonary circulation. The left side of the heart handles oxygenated blood returning from the lungs. Learn more.
What structure separates the left and right ventricles of the heart?
Atrial septum
Interventricular septum
Chordae tendineae
Tricuspid valve
The interventricular septum is a thick muscular wall that divides the left and right ventricles, preventing mixing of oxygenated and deoxygenated blood. It also contributes to the structural integrity of the heart during contraction. The atrial septum separates the atria instead. Learn more.
Which valve prevents backflow of blood into the left atrium during ventricular contraction?
Aortic valve
Mitral (bicuspid) valve
Tricuspid valve
Pulmonary valve
The mitral valve, also known as the bicuspid valve, separates the left atrium and left ventricle. It closes during ventricular systole to prevent blood from flowing back into the left atrium. This ensures forward movement of oxygenated blood into the aorta. Learn more.
Which of the following vessels carries oxygenated blood from the lungs to the heart?
Pulmonary veins
Aorta
Superior vena cava
Pulmonary arteries
The pulmonary veins return oxygen-rich blood from the lungs to the left atrium of the heart. In contrast, the pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs. The aorta distributes oxygenated blood systemically, and the superior vena cava brings deoxygenated blood from the upper body. Learn more.
What is the correct order of blood flow through the heart?
Right atrium ? tricuspid valve ? right ventricle ? pulmonary artery ? lungs ? left atrium ? pulmonary vein ? mitral valve ? left ventricle ? aorta
Superior and inferior venae cavae ? right atrium ? tricuspid valve ? right ventricle ? pulmonary valve ? pulmonary arteries ? lungs ? pulmonary veins ? left atrium ? mitral valve ? left ventricle ? aortic valve ? aorta
Superior vena cava ? right atrium ? mitral valve ? right ventricle ? pulmonary artery ? lungs ? pulmonary veins ? left atrium ? aortic valve ? left ventricle ? aorta
Pulmonary veins ? left atrium ? mitral valve ? left ventricle ? pulmonary artery ? lungs ? right atrium ? tricuspid valve ? right ventricle ? aorta
Blood returns from the body via the superior and inferior venae cavae into the right atrium, passes through the tricuspid valve to the right ventricle, and is pumped through the pulmonary valve into the pulmonary arteries. After oxygenation in the lungs, blood returns via pulmonary veins to the left atrium, goes through the mitral valve into the left ventricle, and is ejected through the aortic valve into the aorta. This precise sequence ensures efficient systemic and pulmonary circulation. Learn more.
Which layer of the heart wall is composed primarily of cardiac muscle and is responsible for the heart's contractile function?
Endocardium
Myocardium
Pericardium
Epicardium
The myocardium is the thick middle layer of the heart wall made up of cardiac muscle fibers responsible for contraction. The epicardium is the outer layer, while the endocardium lines the inner chambers. The pericardium is a fibrous sac surrounding the heart. Learn more.
What is the primary pacemaker of the heart?
Bundle of His
Atrioventricular (AV) node
Sinoatrial (SA) node
Purkinje fibers
The sinoatrial (SA) node is a group of specialized cells in the right atrium that spontaneously depolarize to initiate each heartbeat. This pacemaker activity sets the baseline heart rate. The impulse then travels to the AV node and through the conduction system. Learn more.
Which structure delays the cardiac electrical impulse to allow atrial contraction before ventricular contraction?
Atrioventricular (AV) node
Purkinje fibers
Bundle of His
Sinoatrial (SA) node
The AV node slows conduction of the electrical signal to ensure that the atria contract and complete ventricular filling before the ventricles contract. This delay is critical for coordinated cardiac function. After passing through the AV node, the impulse travels to the ventricles via the Bundle of His and Purkinje fibers. Learn more.
During the ventricular action potential, which ion channel opening is primarily responsible for the rapid depolarization phase (phase 0)?
Potassium channels
L-type calcium channels
Funny current channels
Fast sodium channels
Phase 0 of the ventricular action potential is driven by the rapid influx of sodium ions through voltage-gated fast sodium channels. This creates a sharp upstroke in membrane potential. L-type calcium channels open later during the plateau phase. Learn more.
According to the Frank-Starling law of the heart, what happens to stroke volume when end-diastolic volume increases, assuming constant contractility?
Stroke volume remains unchanged
Stroke volume decreases
Stroke volume increases
Heart rate increases
The Frank-Starling mechanism describes how increased end-diastolic volume stretches myocardial fibers, resulting in a more forceful contraction and higher stroke volume. This intrinsic property helps match cardiac output to venous return. Contractility and afterload remain constant in this scenario. Learn more.
Which change is most likely with increased sympathetic stimulation of the heart?
Decreased heart rate
Decreased force of contraction
Increased conduction velocity through the AV node
Increased refractory period
Sympathetic stimulation via norepinephrine increases heart rate, contractility, and conduction velocity, particularly at the AV node. This reduces AV nodal delay and increases cardiac output. It also shortens the relative refractory period rather than increasing it. Learn more.
In right-dominant coronary circulation, which artery gives rise to the posterior interventricular (posterior descending) artery?
Anterior interventricular artery
Right coronary artery
Left coronary artery
Circumflex branch of the left coronary artery
In approximately 85% of individuals with right-dominant circulation, the posterior interventricular artery branches from the right coronary artery. This pattern defines right coronary dominance and supplies the heart's posterior septum and ventricular walls. In left-dominant hearts, it arises from the circumflex branch of the left coronary artery. Learn more.

Cheat Sheet
Heart Chambers & Blood Flow -
Review the four-chambered structure - right atrium, right ventricle, left atrium, left ventricle - and memorize the blood flow sequence: RA → RV → pulmonary circuit → LA → LV → systemic circuit (American Heart Association). A handy mnemonic is "R.R.L.L.S." (Right, Right, Lungs, Left, Left, Systemic) to nail this path in your heart anatomy quiz.
Cardiac Cycle Phases & Stroke Volume -
Understand the systolic (ventricular contraction) and diastolic (ventricular relaxation) phases of the cardiac cycle and how pressure changes drive heart function (Guyton & Hall). Remember the stroke volume equation, SV = EDV - ESV, to calculate the blood ejected each beat when practicing cardiac physiology questions.
Heart Valves & Mnemonics -
Identify the atrioventricular (tricuspid and mitral) and semilunar (pulmonary and aortic) valves, noting their roles in unidirectional blood flow (Gray's Anatomy). Use the playful mnemonic "Try Pulling My Aorta" to keep valve order straight in your heart structure function quiz.
Electrical Conduction System -
Familiarize yourself with the SA node, AV node, Bundle of His, and Purkinje fibers, which coordinate the heartbeat and set the normal rhythm at 60 - 100 bpm (American Physiological Society). Practice drawing the conduction pathway to ace your heart anatomy and physiology quiz section on electrophysiology.
Frank-Starling Mechanism & Muscle Function -
Learn how the Frank-Starling law (SV increases with greater end-diastolic volume) explains the heart's intrinsic ability to match output to venous return (Circulation Journal). Reviewing this concept will help you tackle questions on cardiac muscle function in the anatomy physiology of heart test.
