Heart

right ventricle

when we talk about the voice of the heart, allot of people think that its your conscience. actually that's not really what happen. the Truth is the voice of God. His Spirit(Holy Spirit) that live in our life. it is apply only for those who believe and received Jesus Christ as his or her own Savior only.

those who has not receive Christ, the voice of heart is only his or her inner being which is his or her spirit.

the reason for this is for the believer, they trusted Holy Spirit with their day today's life or activities. talk with Him in prayer, or just communicate within their heart.

for those who has not, they only talk to them self within their heart.

I guess that's my answer for this question. hopefully others can give better one. God bless.

Left ventricle has the strongest muscles. This ventricle has to pump blood to entire body parts. The blood pressure in the systemic aorta is about 120/80 mm of mercury. This has to be maintained by this chamber. The right ventricle has to pump blood to the lungs only. The systolic blood pressure here is about 25 mm of mercury, much less as compared to systemic blood pressure. When you actually see the muscles of the heart of cadaver, you get the idea very clearly and without further questioning.

A heart attack occurs when the blood flow is cut off to a portion of your heart muscle.

you will die

The wall between the two upper heart chambers is called the septum

Both sides of the heart have an atrium and a ventricle, however, the left side of the heart is thicker and stronger so it has a valve with only two cusps (bicuspid valve). The right side of the heart is not as strong and needs a valve with three cusps (tricuspid valve). Both valves are located between the atria and ventricles.

The answer could br yes and no. Let me explained. You have 3 main arteries on the heart (Left anterior descending, circumflex and the right coronary artery) that supply oxygen to the heart itself. If one of these arteries becomes blocked over a long period of time, the heart can "grow" arteries to the area of blockage to reestablish blood flow (this is called having collateral flow). It is possible that if one of the arteries closes abruptly, sudden death is possible. There are 3 ways of maintaining blood flow or reestablishing flow, (1) medications, (2) balloon angioplasty and (3) Coronary Artery Bypass Grafting or open heart surgery.

Mechanical valves are effective but can increase the incidence of blood clots.

Passively. Blood flows in the inferior vena cava because the pressure in the right atrium is lower than the pressure in the vena cava. Blood flows along this pressure gradient to return to the heart.

Atrial flutter-- Rapid, inefficient contraction of the upper chamber of the heart.

The common wall is called the septum.

The structure of the heart is what makes it an efficient pump. It works continuously without tiring, and it receives electric signals every second and pumps blood nonstop.

The left and right atria (singular atrium) are chambers in the heart. The atria are the upper chambers (ventricles are lower). The left atrium is on the left-hand side of your body as you look down at your own heart; the right atrium is on the other side.

That will vary depending on the individual, and how much effort you expend. Just about the only thing that can be said for sure is that it will beat faster than at rest.

Echocardiography uses ultrasound to view the inside of the heart.
Cardiac Echo/2D Echo

The right atrioventricular valve is also called the tricuspid valve. It gets this name because it has three leaflets.

The main energy supply to the heart is oxygen supplied by the coronary arteries. For more information contactHeartquestionsanswerd@hotmail.co.uk To get ANY heart question answerd. Use this information as a guide only I am NOT a doctor but I know a lot about the heart.

It depends. It depends on how serious the heart defect causing the murmur is, and it depends alot of how strong the drug is. But taking a stimulant drug can definitely put stress on your heart, and if your heart can handle that extra stress, boom- it can't pump blood into its own muscle, and the muscle quickly dies and starts turning black. Then the heart can't pump and your brain and other organs begin to die too. People have definitely died from heart attacks caused by speed/ecstacy, and cocaine. You know ecstacy basically has speed in it, right?

Specialized heart muscle cells in the sino-atrial (SA) node which is located in the right atrium. These serve as the heart's "pace maker".

depends on if you run all day your pulse will go about 40 a minute maybe less when u are not running about 24 hours the least.

Maybe, I don't know, keeping you alive is one thing. Yeah, that seems to be a contribution. Another would be giving your lungs something to do. And pumping energy to your legs and the rest of your body in the form of oxygen carried by red blood cells. Assuming your cells are in an isotonic environment. Which most of the time they are. Unless you drank waaaay too much water or saltwater. Which most people tend to avoid doing. Oh, and it also makes your brain work. Just adding that as a short note.
