We're glad that the video was helpful…best of luck on your exam!
Thank you soo much!
Im studying to be an EMT-B and im struggling when it comes to grasping how the heart works and this helped alot thanks
not that so helpful. but thanks for the info.
Way too basic. Needs more details.
Tricuspid valve (Right AV Valve)
Pulmonary artery (It is the only artery in the human body that carries oxygen-poor blood.)
Mitral valve (Bicuspid Valve)
…they're called NationwideCHILDRENS.
@mattsaho the "lub" sound is created when the tricuspid and bicuspid valve closes, that happens after both atrium had pushed the blood into the ventricles. The "dub", on the other hand, is created or heard when the semilunar valves (pulmonic valve and aortic valve) closes, it happens after the ventricle had pushed the blood to the pulmonary circulation (from R-ventricle thru pulmonary valve) and the systemic circulation (from L-ventricle to aorta and to other parts of the body).
I do not know where the person that made this video got there information from, but blood is never blue no matter how little O2 the RBC's are carring. RBC with low O2 are brick red in color. When RBC are oxygenated the blood turns to a bright red color.
This is just a general video of blood flow. So it would be clear to the viewer that blue = deoxygenated blood and red = oxygenated blood. But look at your veins, what color are they? Are you saying there is currently no blood in ur veins? But first lets define what is a "vein"?
Blood is clearly not red/light red/pink or anything shaded red, unless the oxygen molecule binds to the Iron in the heme group in hemoglobin in the red blood cell.
THUMBS UP THIS FOR THE DETAILS!
1. low oxygenated blood comes from the vena cava, far left blue side
2. goes into the right atrium, middle blue
3. passes through a membrane called tricuspid valve
4,tricuspid valves drop the blood into the right venticle
5.blood goes into the plumanary trunk
6,blood goes into lungs then plumanary veins
7.comes back to Left Atrium
8.pases Bicuspid valve
9.into left venticle
10. into the arota,( top red part) then out of the heart, and throughout your body
Thank you for clarifying for me that blood is actually blue. I was confused by the 5, 286 websites that state that blood is, unequivocally, red and that it is never blue. Had any of them spent just 8 seconds googling, "Is blood blue?, they might not have passed on that faulty information and ruined their crediblility in the process.
Short and informational. Thank you.
Glad you found it helpful!
Like if you watched it more than 5 times not because it is an entertaining video but because you wanted to get the information more clearer.
next time put more details please
i am not able to download this for my ppt…
chill dont add confusion to others about the colors already. if u think this isnt right, just take the video as analogy.
Im having trouble finding an actual accurate depiction of how blood flows through the heart on the internet. Ventricles refill while the atria are relaxed and then the ventricles also do not pump out their entire volume of blood. Why is this the default representation of blood flow?
That was quick
R e a l l y
I didn't understand the path way of blood
wow i will never get those 27 second back
Blood is never blue.
this video wasnt EVEN 27 seconds, it started like 3 seconds later and ended like 10 early lol. Dislikeeeeeeeeeeeeeeeeeeeee
I know that wan
wOw so helpful and weLL dEtailed!
