What cavities has the highest density of cardiac muscle tissue?

The left ventricle of the heart has the highest density of cardiac muscle tissue because it is responsible for pumping oxygenated blood to the entire body. This chamber experiences the most pressure and workload, requiring a strong muscular wall.


Roof of this chamber contains the bicuspid valve?

The bicuspid valve is actually located within the heart, not on the roof of a chamber. It is also known as the mitral valve and is found between the left atrium and left ventricle. Its function is to prevent the backflow of blood from the left ventricle to the left atrium.


What are the chambers in the eye?

There is an anterior chamber and a posterior chamber to the eye. The anterior chamber is from the lens and iris forward to the back of the cornea. The posterior chamber is from the back of the lens to the retina. The anterior chamber is filled with aqueous. The posterior chamber is filled with vitreous.


How is pulse related to systole and diastole?

Systole is when a chamber of the heart (i.e. atrial vs. ventricular systole) is contracting. Diastole is when a chamber of the heart is relaxing. Without qualifying which chamber it is usually assumed to mean the left ventricle.Systole refers to when the heart is contracted and diastole refers to when the heart is relaxed.


What is the function of the heart auricle in the cardiovascular system?

The heart auricle, also known as the atrium, acts as a receiving chamber for blood returning to the heart. It helps to regulate the flow of blood into the ventricles, ensuring efficient circulation throughout the cardiovascular system.

What is the reason for SCD?

Sudden cardiac death is usually caused by ventricular fibrillation (the lower chamber of the heart quivers instead of pumping in an organized rhythm).


What is a ventricular tachycardia?

Ventricular tachycardia-- A rapid heart beat, usually over 100 beats per minute.


What is eccentric left ventricular hypertrophy?

Ventricular hypertrophy means a thickening of the ventricle walls. This can then be described as eccentric or concentric. Eccentric hypertrophy is where the wall thickens but the ventricle itself dilates therefore the wall is thickened but the ventricular chamber remains the same size. Concentric hypertrophy is where the wall thickens which then makes the internal ventricular chamber smaller.


Which cardiac chamber is closest to the spine?

left atrium


How does thickness of myocardium relate to the workload of cardiac chamber?

abdii


What are normal results from a cardiac catheterization?

Normal findings from a cardiac catheterization will indicate no abnormalities of heart chamber size or configuration, wall motion or thickness, the direction of blood flow, or motion of the valves.


What is arrhythmogenic right ventricular?

Arrhythmogenic means it's generating an arrhythmia, and the right ventricle is the bottom right chamber of the heart.


What is the function of the atrium?

The thin-walled priming chamber pump of the heart. Each of the two atria lies above the ventricle, separated by a one-way atrioventricular valve. The function of the atrium is to force the last bit of blood into the main pumping chamber (ventricle) before the power stroke to increase the efficiency of pumping.


What are the function of the left ventricle and the right ventricle?

The left ventricular chamber of the heart is responsible for pumping blood out of your heart and through your arteries to the rest of the body. The right ventricle, receives blood returning in the veins from the rest of the body. It them sends it to be re-oxigenated in the lungs


When the left ventricle contracts does the distance from the apex to the base increase or decrease?

When the left ventricle contracts, the distance from the apex to the base decreases. This contraction, known as systole, causes the ventricular walls to shorten and thicken, effectively reducing the overall length of the heart chamber. As a result, the apex moves closer to the base during this phase of the cardiac cycle.


Why does a physician perform cardiac catheterization on the right side of the heart?

to evaluate tricuspid and pulmonary valve function, in addition to measuring blood pressures and collecting blood samples from the right atrium, right ventricle (lower chamber), and pulmonary artery.


What is your heart doing when it is in systole?

Diastole is when a given chamber of the heart is relaxing. There is atrial diastole and ventricular diastole. Most of the time when talking about diastole we are referring to the ventricular because that is when we measure the diastolic (low) pressure in your systemic arteries, usually the brachial artery.
