Concept explainers
To determine: The reason for the increase in atrial pressure just to the right of C point in the Wigger’s diagram of cardiac output.
Introduction: The atrial pressure describes the average pressure in the arteries of an individual during one cardiac cycle.
To determine: The reason for the decrease in atrial pressure during the initial part of ventricular contraction and then increases.
Introduction: The flow of blood through the heart is governed by the same principle that governs the flow of liquids and gases. The blood flow proceeds from the regions of high pressure to the regions of low pressure.
To determine: The reason for the decrease in atrial pressure to the right of D point.
Introduction: The human heart is made of four chambers: left atrium, left ventricle, right atrium, and right ventricle. The main function of the heart is to pump blood throughout the body via the circulatory system.

- In dilated cardiomyopathy of the left ventricle, the ventricle can become enormously enlarged. Explain why this might lead to regurgitation of blood through the mitral valve (blood flowing from the ventricle back into the left atrium) during ventricular systole?arrow_forwardDoes the atrial rate equal the ventricular rate in this ECG tracing? Explain.arrow_forwardWhy is atrial repolarization not observed in the ECG?arrow_forward
- Why is there a pause after the atrial contraction andbefore the ventricular contraction?arrow_forwardAs blood in the ventricles surges back against the closed AV valves, the first heart sound ("lubb") can be heard. Why does this heart sound occur near the middle of the QRS complex in the ECG?arrow_forwardIf the mitral valve were insufficient, would you expect to hear the murmur (of blood flowing through the valve that should be closed) during ventricular systole or diastole?arrow_forward
- Why is the Sino-atrial node called the pacemaker of the heart?arrow_forwardWhen the right ventricle is pumping to the lungs which valve is there ?arrow_forward"the patient's heart makes a sound at systole, assuming it is the S1 sound made by closing of valves, which valve are involved?" mitral valve and tricuspid valve pulmonary and aortic valve mitral and pulmonary valve aortic and tricuspid valvearrow_forward
- Balloon catheters are inserted into the femoral artery to unblock coronary vessels. Name all the arterial structures, in order, that the balloon catheter passes through from the right femoral artery to the right coronary artery.arrow_forwardWhat is End systolic volume (ESV)? And what does it do?arrow_forwardAtrioventricular valves and semilunar valves have different structures. Explain if high pressure from above or below each type of valve opens the valves. Atrioventricular valves Semilunar valvesarrow_forward
