Heart

First off, know that your heartbeat is mechanically controlled. A node in your body called the SA node (Sinoatrial node) starts the whole process of giving you beats. The SA node is also called the Pacemaker simply because pacemaker means leader, the one who sets the pace in a race, the set of nerves that stimulate the heart to beat. So to make the process easy to understand, lets view it in an orderly list :) 1. The SA node sends electrical impulses from the top chamber of the heart (Atrium) 2. Then the atrium contracts (presses together - squeezes) and sends blood to the bottom chamber (Ventricle) 3. Then the electrical impulses are in the ventricles through a node called AV node (Atrioventricular node) - the 2nd node that sends electrical impulses after the SA node 4. So the impulse spreads throughout the ventricles (right & left), the muscles contract and then pump out blood 5. Blood from the right ventricle goes to your lungs & blood from the left ventricle goes to your whole body. I hope that answers your question

that's why he's asking because he doesn't want to be an idiot anymore LOL.. anyway don't take it serious, I'm just kidding (if it sounds like I'm not, I'm sorry).. anyway, it's not a heart monitor, it's what you call electrocardiogram or simply ECG..

Eletricial signals somethin somethin. They use it since eletrical forces makes the heart pump so that have to use to machine to revive the heart to pump again and... LIVE (TRUST POINTS)

Left ventricle is the strongest and most important chamber of the heart. It receives oxygenated blood from left atrium, and pumps it into the aorta. Thus supplying the body with oxygenated blood. When this is said, all of the chambers are necessary for proper function of the heart.

The heart consists of 4 chambers - 2 atria and 2 ventricles. The smaller atria are about 1/3 the size and volume of the ventricles. The left ventricle is the largest chamber of the heart, with about 3 times more muscle mass than the right ventricle - both ventricles share a similar volume capacity. Due to the predominant size of the left ventricle, it is not surprising that 70% of all myocardial infarctions occur within the left ventricle. While the heart's chambers' primary purpose is to fulfill the mechanical function of pumping blood, other functions include influencing heart rate and serving several endocrine roles.

You ask the person to run very fast for hundred meters. Take the pulse rate for first 10 to 15 seconds. Calculate the rate per minute. After 15 seconds the heart rate starts to drop. The maximum rate comes to be 180 beats per minute.

it goes to the lungs,to get itself oxygenated.

Left ventricle

The four chambers of the heart are the two lower ones, called ventricles, and the two upper ones, called atria (atrium in the singular). The right atrium collects deoxygenated blood from the body and feeds it down to the right ventricle through a valve called the tricuspid valve- from here, the right ventricle pumps blood to the lungs, where it is reoxygenated. This reoxygenated blood returns to the heart and collects in the left atrium, which feeds it down to the left ventricle via another valve called the bicuspid valve. This reoxygenated blood is then pumped back into the body's circulatory system through the aortic valve into the aorta, which is the most important artery in the body. The ventricles are the chambers that do all the 'serious pumping' and both work at the same time, some induction pumping is done by the atria, but they are mainly the collection chambers for the ventricles.

The receiving chambers are the atria (singular atrium). The right atrium receives deoxygenated blood from the body, and the left atrium receives oxygenated blood from the lungs.

The right atria receives blood from the veins (systemic).

The left atria receives blood from the lungs (pulmonary).

The left side of the heart is bigger because it has to pump harder to get the oxygenated blood all the way around your body. The right side merely receives de-oxygenated (venous) blood.

An infection can definitely increase your heart rate. Especially if you have a fever. Your body is working hard to fight off the infection, and in return, your heart rate rises. This is also why you get out of breath when your sick. You're body is doing more to fight infections, even when your not!

The vessel that carries blood from the heart to the lungs is called the pulmonary vein. It is one of the few veins that carry oxygenated blood to the heart. The oxygenated blood enters the atrium of the heart.

Cardiac muscle fibers.

It enters the arteries.

Just drink a glass of milk with each meal, to neutralize the acid,and before bed, but you can also take Gaviscon,but try to avoid if you can, as antacids cause constipation,making the heartburn worse, through straining on the loo.

The interventricular septum separates the left and right ventricles. This muscular wall prevents the mixing of oxygen-rich and oxygen-poor blood.

If ur chest area is hurting then you should seriously get to a doctor. It could be bronchitis or phuemonia. In the worst cases you could have lung cancer ( I highly doubt it) you should really get to the doctor!!

left and right ventricle
right ventricle and left ventricle

The heart wouldn't beat at a constant rate.

Blood from the systemic circulation system is carried by way of the superior and inferior vena cava, both of which empties into the right atrium of the heart. Blood then passes through the tricuspid valve and enters the right ventricle. Next, the blood is pumped out of the right ventricle, through the pulmonary valve, and to the lungs via the pulmonary arteries. Blood gases are exchanged at the lungs as blood flows through the capillary beds of the alveoli. Blood flows back to the heart via the pulmonary veins and enters the left atrium. Blood from the atrium is pumped into the left ventricle through the mitral valve. Finally, Blood then leaves the left ventricle through the aortic valve and enters the aorta. The aorta once again begins the systemic portion of the circulation system and branches off into many arteries.

Exercise allows the body to loose calories and also encourages blood circulation. This will allow also the body to loose fats and encourage circulation of blood all througout the body in turn makes the heart healthy and the body free from fat clogs or artherosclerosis.

Heart rates vary considerably based on a variety of factors including age, fitness level, body type, and activity level.

Most people use the 'resting heart rate' as a guide. Take your pulse when you are sitting down, and have been relaxed and inactive for about 10 minutes. Your resting heart rate could be anywhere from in the 50's to 100.

An average, healthy, 23 year old male should have a resting heart rate that is less than 80. If it's higher, then a little regular cardio exercise should be in your future.

the real heart is hard to draw,thats why the heart symbol(<3) is created to show it by an easier way,and the real heart actually looks gross so creating the heart symbol is really a good idea-BY ORVEN DON E. ESTRADA
