The two changes are associated, but I think what's happening is that they both
have the same root cause.
Historically, it's the release of adrenaline, and other things that immediately begin
sloshing around in all those places at the bottom of the brain with names I can
never remember, the instant the big saber-tooth that I've been stalking for a week
decides it's had enough, and turns around and starts coming at me full-speed.
Those chemicals blast through my arteries, my senses become sharper, and my
heart starts pounding ... exactly what I need, whether I decide to stand my ground
and fight the cat, or turn around and do a Usain Bolt in the other direction.
Did these situations CAUSE the chemistry in my my ancestors' bodies to change ?
Absolutely not. The cause and course of evolution were much less subtle than that.
Over the countless millennia in the caves, some people were born with bodies
that could produce natural stimulants in seconds, and others weren't. All of
these people needed to eat, and they all went out to stalk the cats in the grass.
Most of the cats turned on most of the hunters. Some of the hunters got away
and lived to hunt another day, and some wound up as tasty morsels for the cats.
The hunters that became cat food didn't have as many children as the hunters
that got away, and since children are often born with characteristics that resemble
those of their parents, the population eventually swung in favor of the line of
people who carried their own performance-enhancing drugs around with them.
I never took a Biology course, but that's the way I understand it.
I chose this topic as a science fair project, turns out it was true. Old eople can recognize scents, but their heart does not respond as much as young people. I tested odors such as boiled egg , peppermint, sugar cookie, and blue cheese. Old people really liked the cookie! Turns out your olfactory system (Smell Control) is linked to the limbic system (Emotion Center). When you smell something you really like, you remember the smell. Cool isn't it?'
Yes, All senses affect a humans heart rate. Without senses, our heart rate would most of the time [in the given circumstances] stay the same.
depressants affect the heart rate by its heart rate
The heart rate in the human body doesn't actually affect the adrenal glands. Its the other way around. The adrenal glands affect the heart rate by rising the rate over what it actually should be.
coke cola does effect your heart rate from all the caffeine in the drink. it makes your heart beat even faster
Yes, it can cause a sinus bradycardia (slowed heart rate).
Both the thyroid and adrenals produce hormones that affect heart rate.
depressants affect the heart rate by its heart rate
It increases your heart rate.
Yes, excercise does affect your heart rate. It makes your heart faster of the oxygen and things.
The only way it would affect your heart rate is if you got excited or nervous, which would raise your heart rate.
Rap effects your heart rate because it speeds up your heart rate.
The heart rate in the human body doesn't actually affect the adrenal glands. Its the other way around. The adrenal glands affect the heart rate by rising the rate over what it actually should be.
there are nevers that affect your heart rate there are twoSympathetic and parasympathetic (vagus).hope i helped :D
Your heart rate can be affected through release in hormones, or caffeine, or exercising, or many drugs can also affect the heart rate by decreasing it.
Yes, caffeine increases your heart rate.
Caffine will speed up the heart rate.
No :)
No.
