What is a synonym for 'tricuspid'?
Tricuspid valve (located between the Rigth Atrium and Right Ventricle in the heart) is also known as the Right Atrioventricular valve. The name "Tricuspid" indicates its structure, or form, as it has three flaps (or cusps), against the Bicuspid Valve (located between the Left Atrium and the Left Ventricle), which only has two. For more info see the related links.
What is the treatment for Tricuspid valve insufficiency?
usually does not require treatment, since a tiny leakage occurs in most normal people. In certain cases, however, if there is underlying pulmonary valve disease or lung disease, those conditions should be treated.
What two heart chambers contract last in a normal cardiac cycle?
FIRST: Atrial contractions: - Right atrium forces the blood into the Right ventricle (through the tricuspid valve) - Left atrium forces the blood into the Left ventricle (through the the Mitral (or Bicuspid valve) FOLLOWED BY: Ventrical conctractions: - Right ventricle forces the blood into the Pulmonary trunk (through the Pulmonary semilunar valve) - Left ventricle forces the blood into the Aorta (through the Aortic semilunar valve). Contractions in both atrium happen simultaniously, just like contractions in both ventricles. More info can be found on http://en.wikipedia.org/wiki/Heart
Why are organs more complex than tissues?
according to McGraw-Hill, an organ is more complex, learned from my anatomy homework
Is an atom just a solid particle or is it more complex than that?
Far more complex.
Why does mitral valve prolapse occur more often than tricuspid prolapse?
Because there is much more pressure on the mitral valve.Mitral valve prolapse occur more often than tricuspid valve prolapses because the mitral valve is attached to the left ventricle by two chordae tendinae, whereas the tricuspid valve adheres to the right ventricle via three chordae tendinae. Thus, the tricuspid valve has more stability and is less likely to prolapse.
Why human heart does not has bicuspid valve instead of tricuspid valve?
The human heart has both Tricuspid and a Bicuspid Valve. The Bicuspid Valve is more commonly know as the Aortic Valve. All that bicuspid means is that there are only 2 leaflets in the valve instead of the normal three leaflets that would be found in the tricuspid valve or the mitral valve.
What is the valve between between the left atrium and left ventricle?
right atrium - right ventricle = TRICUSPID VALVE; right ventricle - lungs = PULMONARY SEMILUNAR VALVE; lungs - left atrium = not really a valve, more a perforation in the left pericardium; left atrium - left ventricle = MITRAL VALVE; left ventricle - aorta = AORTIC SEMILUNAR VALVE.
Where can someone get a mitral valve replacement done?
You can get a mitral valve replacement done at a surgical institute or hospital by a qualified surgeon. You can learn more about mitral valve replacement online at the Wikipedia.
What is the common name of the sinoatrial valve?
The sinoatrial valve is more commonly called the mitral valve.
What is the valve that is between the ventricles and their arteries?
Between the Atria and Ventricles of the heart are the aptly named Atrioventricular valves. The valve between the right atrium and ventricle is called the Tricuspid because id has three Cusps (of small flaps the are pushed together and closed when under pressure). The valve between the left atrium and ventricle is called the Bicuspid because it has two cusps, of more often called the Mitral Valve because its two cusps look like a bishops hat.
What is mitral insufficiency?
Mitral insufficiency is a disorder of the heart in which the mitral valve does not close properly. It is also called mitral regurgitation and more info can be found here: en.wikipedia.org/wiki/Mitral_regurgitationMitral
Is the tricuspid valve is shaped like a half moon?
It actually looks more like a triangle.
Why the mitral valve is most commonly involved in rheumatic heart disease?
Rheumatic heart disease is caused as a sequel of beta haemolytic streptococcal infection. It affects the mitral valve most commonly. All the four heart valves originate from the same embryonic cell rest. The golden question is why the mitral valve in involved most commonly and not others. The reason is very simple. You have to look at the hydrodynamics of the blood flow through the cardiovascular system. Blood flows in similar fashion through right and left side of the heart. But the pressure in left side is much more than in the right side. It is about 120 mm of mercury in the left and about 25 mm of mercury in the right side in the heart. So when the left ventricle contracts, blood strike on the mitral valve with much greater force than it strikes the tricuspid valve as the valve closes down. So the antibody/ antibodies in the blood also strike with great force on the mitral valve. So it is most commonly involved. The second most common valve is valve in aortic valve. Here again the pressure is high. About 120 mm of mercury. But there is way out for the blood to flow away. So the pressure is not maintained in sustained way. The strike of the blood against the valve is not as consistent. The third valve to get affected is tricuspid valve. Here the pressure is less as compared to the left side of the heart. The forth valve is pulmonary valve. Here the cavity is not tightly closed. Blood can flow away. So it is least affected.

Abnormal narrowing of the opening of the mitral valve is?
An abnormally narrow mitral valve is a condition called mitral stenosis. The mitral valve is situated between the left atrium and left ventricle. This means the left atrium has a more difficult time filling the left ventricle. Since the left ventricle needs to pump blood to the entire body, incomplete filling of this chamber means less cardiac output to the entire body.
Why bicuspid valve has two cusps and tricuspid valve has tree cusps?
Still needs a valid answer. What's the purpose functionally of the 2 valves being differently shaped? I was proposed the same question by a student today, and the only answer I can come up with, besides because our common ancestors have it that way is there is a limitation of room in left ventricle. However what we think causes it is the fusion of the valves tissue from 3 cusps into 2 in human development.
