Heart

It depends on the size. It will always allow blood to mix - mostly from left to right, thus increasing both the flow and the pressure on the pulmonary side.

The risk to health and life varies from negligible to major.

Blood flows from your superior and inferior vena cava into the right atrium, through the tricuspid valve into the right ventricle, and is then pumped into your pulmonary system. The oxygenated blood returns from the pulmonary vein into the left atrium, through the bicuspid valve, and into the right ventricle - where it is pumped into the body. The lower chambers of the heart, or the ventricles, are much more muscular because of all the pumping they do. The valves (bicuspid and tricuspid) prevent the blood from going "backwards" so to speak, and returning to the atria while the ventricles are contracting.

the heart is a muscle, and every muscle needs blood because the blood caries oxygen to the cells of that muscle which is then converted into energy and this is what makes our bodies work. your heart however is a special muscle that pumps your blood to all of the muscles in your body.

5000 liter of blood every day

Both the left and right ventricles of the heart pump blood out of the heart, the difference is in where the blood goes. The right ventricle pushes blood into the pulmonary artery where it flows to the lungs and becomes oxygenated. This blood returns to the left atrium through the pulmonary veins and is then pushed into the left ventricle. The left ventricle then pumps the oxygenated blood out of the heart and into the aorta. This blood then travels through arteries and capillaries throughout the whole body supplying tissues with oxygen and removing carbon dioxide. Since the left ventricle is responsible for pushing blood a greater distance (throughout the whole body as opposed to straight to the lings) it tends to be more muscular than the right ventricle.

MVP (mitral valve prolapse) is generally considered to be present at birth, although quite often it isn't diagnosed until one's twenties.

Usually MVP is not extremely dangerous; very rarely, it has caused sudden death by cardiac arrest.

Some people with MVP take medications such as Metoprolol to regulate their heart rate; others use pacemakers. A third option, less often used, is to implant a defibrillator that only activates if a life-threatening cardiac arrhythmia occurs.

MVP is a mild to moderate problem with a valve that causes a slight heart murmur. It is most common in white females who are slightly underweight, but can happen in anyone.

Cardiomegaly is not a condition requiring treatment - it is a symptom of another disease process. As such, the cardiomegaly is not treated, the underlying process is treated.

The most common cause of cardiomegaly is hypertension. Treatment of the hypertension may result in decreasing cardiomegaly, but this is not typical.

Other conditions which result in cardiomegaly include myocardial infarction, congestive heart failure, and pulmonary hypertension. Renal disease is also a less common cause. For congestive heart failure and myocardial infarction, ACE inhibitors can be used to help prevent remodeling of the heart and decrease cardiomegaly.

4 chambers, the Left and right Atrium which are on the top and the left and right ventricals which are on the bottom

Most people who have mitral valve prolapse do not require treatment or any lifestyle changes. It is not a life-threatening disease, but regular check-ups with your physician are advised. In most cases, limiting stimulants such as caffeine or cigarettes is all that is needed to control symptoms. Specific treatment for MVP is generally based on the patient’s overall health and medical history, extent of the disease, signs and symptoms. Treatments may include beta blockers or blood thinners, anticoagulants, adequate hydration, support stockings or surgery.

Actually two chambers of the heart is more muscular (so basically one side of the heart) Because the one side of your heart only has to pump blood to the lungs were it gets oxyginated but the other side of the heart (more muscular side) has to pump the blood all the way to your toes, and every other organ in the human body! So it has too be more muscular too perform the necessary task that it is asked to do!

The cardiac sounds (typically described as lub-dub) are caused by the closing of the cardiac valves. The first sound (lub) is caused by the closing of the mitral and tricuspid valves and the second (dub) is caused by the closing of the aortic and pulmonic valves.

Heart is an organ. It's a pumping organ which pumps the blood to the whole body. Organ means a working part of an organism (system)\

Since heart is a working part of our body, therefore it's an organ

If your heart had only two chambers then oxygen-rich blood would be diluted by oxygen-poor blood and your body would not get oxygen as efficiently as it does. Efficient circulation is necessary for mammals such as humans to maintain a high metabolic rate.

No, the tricuspid valve permits one-way blood flow from the right atrium to the right ventricle. There is no valve or natural opening that allows blood flow from the right atrium to the left atrium.

Pulmonary semilunar valve

(pulmonary valve)

the process goes this way. at first all the deoxygenated blood is collected from upper parts of the body through superior venecava and lower parts of the body through the inferior venecava. then it enters the first right chamber of the heart then passes through tricuspid valve to lower right chamber .then it is carried to the lungs through pulmonary artery . there,it gets mixed with oxygen with the help of haemoglobin in the blood. this oxygenated blood gets carried to the left chamber of the heart through pulmonary vein. then it passes through bicuspid valve to the lower left chamber and finally it is pumped out to different parts of the body.

Some heart rate monitors come with a chest belt and a wrist watch, whereas some consist of only a wrist watch. Those with chest belts can monitor your heart rate continuously while you are wearing them, whereas those without a chest belt generally can't. The wrist watch is used to display your heart rate and for you to adjust various settings.

A chest belt can communicate with the wrist watch with analogue or digital transmission. With an analogue transmitter, you can interface with gym equipment (treadmills etc). With a digital transmitter, you can't do that but you won't get interference from other heart rate monitor users nearby.

Heart rate monitors vary a lot in features. At a minimum, it should allow you to set your target zone i.e. the lower and upper heart rate limits within which you will exercise. And if you exercise above your upper heart rate limit or below your lower heart rate limit, then it should beep to remind you to either ease up or work harder. For many exercisers wanting to lose weight, it may be a good idea to get a heart rate monitor with a calorie counter.

enforce a one way blood flow through the heart chambers
the valves prevent the blood from going backwards. they keep the blood flowing forwards! we just dissected a heart in science today so i know for sure thats what they do :)

Diastole is the relaxation phase of the heart.

tricuspid valve

Answer for anyone looking is the fact that the cardiac muscle never stops, it cannot, otherwise you would die.

your semi lunar valves stop slop from entering your left aorta and your lunar valves stop crud from entering your right ventricle. this is the purpose of your valves. but this is different in dogs as your septum helps fight against testicular torsion.

Blood can enter the heart through either the superior or inferior vena cava. After this, it enters the right atrium, passes through the tricuspid valve, enters the right ventricle, and passes through the pulmonary valve and into the pulmonary artery. From there, it enters the lungs, become oxygenated, and reenters the heart by way of the pulmonary veins. It goes into the left atrium, passes through the mitral valve, and enters the left ventricle. Next it passes through the aortic valve, enters the aorta, and it is then pumped through the rest of the body.
