Leonardo was able to survive and prosper in the world because he produced military weapons for the rulers of the world. The real question you need to ask is how many Leonardos are currently punching a cash register or begging on the street or sitting in a refugee camp because they either refuse to give aid and comfort to the Archons, or are actively suppressed and derided because they think differently than everyone around them.

@cainmartin4131

I don't know the answer for sure, but here is a guess. The ambient pressure and the blood pressure are one system, it's not 3psi inside the body and 15psi outside, the blood in the body is actually under pressure. We know this from scuba divers getting "the bends"; caused by gasses dissolved in their blood at pressure expanding on resurfacing. Then, because blood is ~80% water, and very soluble, parts in contact with the water will just go into solution and mix. It's then just one liquid with a higher concentration of 'blood stuff' the closer you get to the wound. I would guess that you will bleed at about the same rate as usual, however clotting will be less likely since platelets and proteins which would usually cause clotting will get washed away by the water. You would probably bleed for longer and ultimately lose more blood as a result.

@Pyriphlegeton

5 жыл бұрын

Well, blood circulates through the body in a continuous system. So a cut is like opening a continuous tube (say, in ring form). Over the length of a blood vessel, there are multiple systems pushing blood in one direction. The heart pushes it out the one side and pulls it in again on the other through negative pressure of the opening hollow organ that it is. Also arteries push blood actively and veins possess one-way valves. So, if the ambient pressure of water is lower than the pressure the heart can create, I suppose it would rush in the one side, towards the heart. Assuming you'll live, the heart would pump blood out of the other side of the cut continuously. If the water pressure is higher than what the heart can create and the one-way valves in the veins can hold back, it would rush in both sides of the cut vessel and compress the blood within the circulatory system until pressure homeostasis is reached. That's my guess.

Leonardo is, imo, the greatest genius in recent history. He made so many contributions in so many different areas that it is even hard to grasp the full scope of his work. Many of his inventions were so ahead of his time that only nowadays have we found good uses for them.

I love how even your first video is really high quality.

Your description of how a doctor would describe the aortic valve closing is exactly how I would have explained it... made me laugh. Great video!

Incredible guy, that Leonardo. He had a hard time finishing his paintings but I can understand why: he had so much more to do. Thank you for the explanation.

Very interesting! I just looked back though my old university textbook and it says that the shape of the Sinus of Valsalva was there to cause vortices, but rather than to close the aortic valve the purpose was to stop the cusps of the aortic valve from obstructing the coronary arteries. And yet earlier in the book it says the atrioventricular valves are closed by similar vortices.

@musaran2

5 жыл бұрын

It might have a common evolutionary origin. Cusps being in the way reduce flow, thus a bulge to hold them would be selected for. Cusps hitting the wall induce wear and trauma, thus a bulge shape causing a back vortex would be selected for. The vortex also helping them to close might just be a happy bonus.

At this point I am convinced that DaVinci was just normal dude who times travelled back and use his wikipedia knowledge to become an intelectual there.

DaVinci was 500 years ahead of his time. His wisdom and genius was simply unthinkable and not fully understood. I did many of my projects in high school and in university on this mans genius . I got perfect marks on everything he theorized.from Submarines, helicopters, hearts to paintings that will never be fully understood. This man is one of my idols and mentors, posthumously .

Leonardo use theorizing and then did an experiment to test his theory. In other words: he used the scientific method before this method formally existed. It should therefore be no surprise that he was proven right. What is surprising is his consistent use of the scientific method in this and other cases.

I was jealous of leo since childhood. I aspire to be as multifaceted. He truly was the embodiment of imagination and innovation. Its pretty inspiring actually. Edit: even though not all of his ideas worked, they were still very intelligent in design for the time period. They had a lot of thought put into them and I think if he had a better theory of aerodynamics in particular he might have invented a flying machine much earlier in history which is fascinating to think about.

The guy was a genius... No doubt about it.. And thanks a lot for this video.. Was not aware of this fact

I am doctor and I didn't know this. I studied the backflow cause the closer and S2 sound . But that's a good point. That if this is the case then every backflow cause closure of semilunar valve after some regurgitation . And to be honest this has gone through mind. But I easily discard this fact and accepted what I studied .

Truly incredible. Funny, also.
