Cardiac output is calculated as:
Answer: Heart rate multiplied by stroke volume
Cardiac output (CO) = Heart Rate (HR) × Stroke Volume (SV), representing the total blood ejected per minute.
The right ventricle primarily pumps blood to the:
Answer: Lungs via the pulmonary artery
The right ventricle ejects deoxygenated blood through the pulmonic valve into the pulmonary artery toward the lungs for oxygenation.
The P wave on an ECG represents:
Answer: Atrial depolarization
The P wave reflects electrical depolarization of the atria, initiating atrial contraction.
Which vessels return oxygenated blood from the lungs to the heart?
Answer: Pulmonary veins
The four pulmonary veins carry oxygenated blood from the lungs back to the left atrium.
The coronary sinus drains venous blood from the myocardium into the:
Answer: Right atrium
The coronary sinus is the major venous channel draining cardiac venous blood into the right atrium.
Isovolumetric contraction occurs during which phase?
Answer: After mitral valve closure and before aortic valve opening
Isovolumetric contraction is the brief phase after mitral valve closure when ventricular pressure rises rapidly before the aortic valve opens, with no change in volume.
