What controls the vital functions of the body?

23 Apr, 2023 by Dane Raynor

Have you ever wondered what’s happening behind the scenes that keeps your body running smoothly? Sure, we all have a basic understanding of things like breathing and digestion, but how do these processes actually work? In this article, we’re going to explore some of the major players in keeping our bodies functioning properly.

Meet Your Autonomic Nervous System

Your autonomic nervous system (ANS) is responsible for controlling many essential bodily functions that happen without us even thinking about them. This includes everything from regulating our heartbeat and breathing to managing our internal temperature and more. The ANS is divided into two branches: the sympathetic nervous system and the parasympathetic nervous system.

Sympathetic Nervous System: Fight or Flight

When we encounter a perceived threat – whether it’s an actual physical danger or something more mental, like public speaking – our sympathetic nervous system kicks into gear. This response triggers a release of hormones like adrenaline that prepares us physically to either fight off a threat or run away as fast as possible.

Some key responses triggered by the sympathetic nervous system include:

  • Increased heart rate
  • Constricted blood vessels
  • Dilated pupils
  • Sweating
  • Increased respiration

Parasympathetic Nervous System: Rest and Digest

On the flip side, the parasympathetic branch helps regulate “rest-and-digest” activities, such as digestion, urination, salivation, lacrimation (tear production), defecation etc.. When you feel relaxed after indulging in your favorite treat – maybe ice cream -, your “parasympathetics are popping”.

The following functions taking place within your body when under parasympathetics influence :

  • Decreased heart rate
  • Dilated blood vessels
  • Contraction of bladder muscles
    • Food digestion
    • Saliva production
  • Gastrointestinal tract motility

The Power of Hormones

While the nervous system plays a major role in controlling our bodies, hormones are also key regulators. These chemical messengers can impact everything from growth and development to sleep and mood.

Adrenaline: The Ultimate Stress Signal

On top of its sympathetic response, adrenaline (epinephrine) is one hormone that gets us through moments of stress or danger with superhuman abilities. When we encounter potentially dangerous situations – like godawful alarm clocks -, adrenaline floods our system, increasing heart rate and blood pressure while boosting oxygen delivery throughout the body for optimal performance. Not so invincible now?

Blood Sugar Regulation

Maintaining a healthy blood sugar level is essential for overall wellness. Your body’s endocrine system manages this delicate balance between two hormones: insulin & glucagon hormones.

Insulin: The Keeper of Blood Sugar Optimums

Insulin keeps watch over your burning chamber by regulating glucose levels released into your bloodstream after you eat food containing carbohydrates., Strangely enough but arguably undeniable, it’s quite similar to doorkeepers inspecting folks before they enter some hotshot club/restaurant/place like Harvard University entrance(You got an inner laugh there).

When glucose applies as a knocking signal on insulin receptors within cells primarily located in liver then muscles which prevents stored glucose from building up inside blood vessels; knock down! Cell entry granted! Heyyy! You’re good to go until further errands require more burning fuels!

Glucagon: Keeping It Steady

Conversely , when your body assesses low insulin levels indicating dire need for increased energy stockpile consumption during relevant biological events such as stringent exercise(as if I’ve ever), somatostatin hormone halts(insulin & even pancreas states oopsie daisy) and as a part of glucose-optimate managing strategy glucagon hormone comes into play.

The glucagon team, converted from protein-rich amino acids dependent on insulin suspension in liver, muscles & brain , encourages sugar released to blood vessels to normalize body blood sugar levels. Ensures sugar neutrality!

Tying It All Together

It’s clear that there are many different forces at work keeping our bodies running smoothly (or sometimes not so much)!. Whether it’s the nervous system triggering physical responses or hormones balancing out our internal chemistry. At the end of day – always ensure that you’re taking care of yourself whether spiritually, mentally or physically because when your mind,body & soul aligns- guess what? You can take on the world!

Now go tackle your day with all these super-cool bodily functions working together like interconnected superheroes… saving your life!
