What is the function of the auricle in the heart and how does it contribute to the overall cardiac function?

The auricle in the heart acts as a reservoir that helps collect blood and allows for efficient filling of the ventricles. This contributes to the overall cardiac function by ensuring a steady flow of blood into the heart chambers, which helps maintain proper circulation and cardiac output.


What is occurring during the diastolic period?

Diastole is the phase in the cardiac cycle that allows filling of blood into the ventricle. It corresponds to the lower number in the blood pressure measurement. A normal upper limit of the blood pressure falls in the range less than 120/80 mm Hg. Above this value, it is considered pre-hypertension based on The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure.During the diastolic period the ventricle is in the fifth phase of the cardiac cycle. This phase is termed isovolumetric relaxation which occurs immediately after the second heart sound. In this phase, all valves of the heart are closed. The volume of blood in the ventricle during this phase of the cardiac cycle remains constant. Following the fifth phase of the cardiac cycle is the rapid filling of blood into the ventricle. This cycle corresponds to the opening of the mitral and tricuspid valves located between the left and right atria and ventricle, respectively. The next phase of the cardiac cycle, called diastasis, is the longest phase of the cardiac cycle. In this cycle, the ventricle continues to fill with blood but at a much slower rate. The final phase of diastole corresponds to the first phase of the cardiac cycle. In this phase of the cardiac cycle, the atria contracts to provide additional filling of blood into the ventricle. After the final phase of diastole, the systolic phase of the cardiac cycle begins.


Why is the sphincter at the top of the stomach called the cardiac sphincter?

The sphincter at the top of the stomach is called the cardiac sphincter because it is located near the heart, which is known as the cardiac region. This sphincter helps regulate the passage of food from the esophagus into the stomach, preventing backflow of stomach contents into the esophagus.


What is the relaxing phase of the cardiac cycle?

The relaxing phase of the cardiac cycle is called diastole. During diastole, the heart chambers (atria and ventricles) relax, allowing them to fill with blood. This is followed by the contracting phase called systole.


What is the muscular portion of the cardiac wall?

The muscular portion of the cardiac wall is called the myocardium. It is responsible for contracting and pumping blood throughout the body. The myocardium is made up of cardiac muscle cells that are interconnected to allow for coordinated contraction of the heart.

Sometimes fluid collects between the heart and the pericardium called pericardial effusion. When the fluid accumulates, it can squeeze the heart and prevent it from filling with blood.
