In school, we are learning about blood and the heart. I decided that this would be a good, sturdy subject to discuss with, which may actually help me study! So, please tell me all you know about the heart and I will respond accordingly! smile

Some facts I know:
~ The heart is a muscle
~ The smell off meat / the heart is the same smell as rusted nails, due to the fact that the oxygen in the air is combining with the iron in your blood!
~ The heart is 2 pumps. One pumps de-oxygenated blood to the lungs, and the other pumps oxygenated blood to the rest of the body!
~ The average human heartbeat is 72 beats per minute!
~ Cyanide poisoning does not stop the heart, it prevents the cells in the body from using oxygen!
~ Bloods characteristic colour comes from the chemical, haemoglobin, which is what transports oxygen around in the blood!

Let's see...if you have an average heart rate of 60 beats per minute, and you live to be 75 years old, your heart will beat

(75 years/life)(365 days/year)(24 hours/day)(60 minutes/hour)(60 beats/minute)

= 2,365,200,000 times in your life! That's 2.4 billion.

Unfortunately, the heart is a very untamed creature. When we are scared, our heart pumps blood a lot faster, when we are angry it does as well, when we are excited, it still pumps faster. When we are perfectly calm, it slows down considerably. It is impossible to find an accurate average (Yay, assonance!), because it depends on the lifestyle of the person! smile sad smile

True. People who smoke have slower heartbeats, as well, and larger people (not fat, but in all dimentions) have slower heartbeats, and shorter people (like toddlers) have faster heartbeats. [unrelated]The second was supposedly based off of the heart's beat, but it must have somehow gotten messed up.[/unrelated]

xD I'm pretty sure that my stomach is larger than my fist in size, because I can eat a greater volume of food than that of my fist.

But maybe you're right, and it's just that food gets chewed and thus compressed into a smaller volume, or my fist is small. ^^

I thought that this was about some weird RPG game XD

I think the stomach is like the size of two fists.

At school we dissected a heart and I stuck my hand inside it and walked around with a heart on my hand. Everyone screamed. XD

xD He was there in the classroom, but he took it more seriously >.> I just waved my dissected heart at people, he did what you were supposed to do ;3

It was a pig's heart, which had been in someone's freezer o.o
And Albertt911 is still alive, sadly.

Joke, love you really Al :')

We dissected sheep hearts last year in science, and we had to identify the different parts of it. smile

It was a cows heart, btw.

Or was it a pigs? :L

werdna123 · 2011-09-20 11:15:16

Uh oh. Of all the time's for Albertt911 to come on? When we were discussing disecting his heart.

>.>

Edit: I think I've off-topiced this topic for it not to be an 'intelligible discussion'. >.<

Oh, I thought it was a human heart.

werdna123 · 2011-09-20 11:16:42

Nah, that would be creepy. Although any heart would be kinda creepy of course.

My heart was frozen in the middle, and it smelt of zombie -_______-
It was a pig's heart, I'm sure.

@werdna - LOL yeah, I'll get Al one of the days and dissect his heart ;D

Still discussing hearts, just not facts about them :3
2:30am?!

Ah, takes me back to my Human Anatomy and Physiology class. big_smile

Did you know each human heart cell beats to it's own, well, beat? If you take one heart cell beating slowly and connect it to one beating quickly, they'll eventually beat together at the same rate at a beat somewhere in-between. smile

Cool! How'd you find that out?
