@Stivino
Yes a word like portmanteau but I know what that one is, and it's not it!

 

[Justin Passing]

Hopefully interesting if you didn't know it...

If you use a stethoscope, you can hear a heart going lub-dub, lub-dub
Exactly what is making the lub and the dub noises?

If that's too easy: if you went cardiac, pyloric, oddi , choledochus and took the next left, where would you be?

 

[Justin Passing]

Someone must have an idea how their heart works?

 

[opps]

It is turbulence caused by valves opening and closing.

 

[Justin Passing]

No

Lulu's heart goes boom bang a bang.

]You may be very clever
But however, can't you see,
My heart beats much too much.
At a certain tender touch,
It goes boom boody-boom boody-boom boody-boom
Boody-boom boody-boom boody-boom-boom-boom,
Him: I like it!
Boom boody-boom boody-boom boody-boom
Well, goodness gracious me

But what are those noises from, exactly?

Bjork

 

[Justin Passing]

I am not a Bjork.
I'm Reporting you for abuse.

Spoiler: Buddy

 

[Justin Passing]

Well you're all useless.

The lub is the lower two valves in this, snapping shut, the dub is the upper two.
Everything's a bit elastic, so when the pressure reverses, they shut with a shock which is what you feel and hear.
The lung loop, goes from pulmonary to mitral valves.

For the other thing, look up ercp.

 

[danechip]

That looks rude...

 

[Justin Passing]

Nah. It's car engines which go
suck
squeeze
bang
blow.


OK back to general knowledge:
