- This video describes the anatomy of the tricuspid valve, a.k.a. the right atrioventricular valve, where we discuss the its location, cusps and function. Take a closer look at the heart valves here:

As its name suggests, the tricuspid valve has three separate cusps, or leaflets, and is located between the right atrium and right ventricle of the heart. Its function is to prevent back-flow from the right ventricle to the right atrium during cardiac systole.
The three cusps of the tricuspid valve are the anterior, posterior and septal cusps; these are also known as the anterosuperior, inferior and septal leaflets, respectively, in clinical practice.

Hey there! Hope this short video tutorial on the tricuspid valve got your heart PUMPING! :D Let us know what you think in the comments below! Wanna know more about the anatomy of the heart? We have all you need right here! khub.me/kmek9
Thanks kenhub for the help 👌
I want to know about more other 3 valves and the functions done by the valves!!
Muito interessante preciso muito dessas informações sou cardiopata
We're happy to hear that you liked our video :) Have fun learning!
Is this why I feel pulse at back of neck ?
Why there is tricuspid vulve between right atrium and ventricle while there is the bicuspid vulve between left atrium and ventricle? What's the reason of this difference of cusp number in those two cases?
The right side of the heart pumps blood to the lungs at low pressure so the blood can be re-oxygenated, and the left side pumps the oxygenated blood from the lungs at high pressure to reach the whole body parts.
The right atrium and ventricle has tricuspid. Listen, if u push a smaller amount of fluid in larger area you have less pressure than if you push a lager amount of fluid into a smaller area. As you know that the left ventricle push oxygenated blood Forcely to reach the whole parts of body. By the time it reaches to right atrium and filling it with low pressure . The right side of heart move same amount of as the left side but at low pressure so it is important that valve open at wider angle to pass the same volume to pass through. The three parts of valve allow it to open more circular and thats the reason.
Why microphage have big size ? gives me a reason .
A macrophage is a type of phagocyte, which is a cell responsible for detecting, engulfing and destroying pathogens and apoptotic cells. The macrophages are significantly larger than the pathogens to be controlled. Otherwise, the phagocytes would not be able to phagocyte pathogens, since the pathogens must be completely encapsulated, because the digestive enzymes must not enter the extracellular space. Otherwise they would get in contact with body-specific proteins.
Unfortunately we can't go further into this topic at this point. However if you are interested I would recommend you take a look at our histology section at Kenhub. You can find it here: www.kenhub.com/en/start?lecture=histology
I'm sure that it will be helpful for your studies!
Why the right position of a heart have tricuspid valve?
Hi Arooba! This is a really hard question :)
Maybe the reason that in the right side of the heart we have a tricuspid valve lies in some emryological factors.
The right side of an embryo heart has 3 cusps (anterior, posterior, and medial) between the atrium and ventricle. This evolves to the tricuspid valve.
The bicuspid valve is on the left side, evolves from two cusps (anterior and posterior).
Now the specific reason why in the embryo there are 3 cusps on the right and 3 cusps on the left maybe has something to do with the blood circulation (hemodynamics) in the embryo's heart.
This very interesting paper (www.ncbi.nlm.nih.gov/pubmed/25191277) says that when the pressures in an embryo heart increases, the tricuspid valve can appear to have a bicuspid valve pattern. Somehow, hemodynamics seem to be a factor that alters gene expression during valve development.
We hope this helps! Have fun learning :)
Thank you sr
You're welcome :) Have fun learning!
Kenhub - Learn Human Anatomy - typing error, should read " in the embryo thats 3 cusps on right and 2 on the left "
