Let’s Review Anatomy!
It’s official: We have been scribbling down Anatomy Fun Facts for 6 months now! For this month, we have decided to spotlight our favorites.
Review is always good for the brain.
As we have been saying: You only get ONE BODY. There are no trade-ins or upgrades!
Here are our Favorite Fun Facts:
1.) Skeletal System: ONE HUNDRED SIX BONES IN YOUR HANDS AND FEET
There are 27 bones in each hand, and each foot has 26 bones. That means together your two hands and two feet have 106 bones; more than half of the bones in your entire body can be found in your hands and feet! With so many working parts, it is very important to find the right shoes for your body when working out.
2.) Muscular System: MOVING JOINTS
Bones hold us upright, but without muscles we would be going nowhere! Most moving joints have, at least, two sets of muscles attached to them and act in opposition to aid in the joint’s utility. For example, muscles at the elbow: one set bends, while another set straightens it.
3.) Cardiovascular System: Our Beating Heart
There are specialized cells in our hearts that coordinate the muscle contractions of our hearts. They have an intrinsic rhythm that allows them to dictate our hearts’ beating WITHOUT input from the brain. Our brain only gets involved when our heart rate needs to be slowed down or sped up.
4.) Respiratory System: Exhale
In some exercise regiments, we are instructed to “breathe out all of the air” from our lungs. It may feel as though you have achieved this but, luckily, this is physically impossible. There is always residual volume left in your lungs. If our lungs were able to be evacuated of all air, then they would collapse on themselves and prohibit air flow from ever occurring again!
5.) GI Tract: Long Tract
The gastrointestinal tract is simply one long tube with specialized “pouches” along the way. Food flows through your body in this order: mouth, throat, esophagus, stomach, small intestines, colon. The entire tract is about 30 feet (9 meters) long.
6.) GI Tract 2: Your Liver
The liver has many diverse functions within your body, most of which can only be performed by the liver. This organ houses energy stores, detoxifies ingested foods, and filters toxins that find their way into your blood stream. Take good care of this important organ by avoiding excessive amounts of alcohol and acetaminophen.
