The human body is an unbelievably complex system consisting of thousands of different parts that work together to keep us alive.
In fact, it’s so impressive that you could name hundreds of body parts starting with just the letter „A“!
In this article, we’ll go over some of the most interesting ones to help you get a better understanding of your own body.
So, without any further do, here are some body parts that start with A!
The Most Common Body Parts Beginning With A
The abdomen is one of the most important human body parts that start with the letter “A”.
It’s the part located between the chest and the pelvis, and it’s more commonly known as the stomach.
The abdomen serves many different functions, all of which are essential to our lives.
The abdominal muscles assist us in breathing, moving, as well as keeping our posture.
There are also many important organs in the abdominal area, including the appendix and bladder.
It’s safe to say that the abdomen is one of the most crucial parts of the human body.
Additionally, the appearance of the human stomach has different cultural connotations around the world.
Some cultures see abdominal fat as a sign of wealth and prestige, while others perceive it as a sign of an unhealthy lifestyle.
Overall, the abdomen supports our body in more ways than one.
As such, it’s one of the most important human body parts starting with the letter “A”.
We all know what human arms are.
We use them every day to grab things, pet our dogs, and hug our loved ones.
Humans rely on their arms almost as much as they rely on their legs.
In fact, even this article is written using two arms!
Arms consist of three different bones: the upper arm bone, and two other bones that make our forearms.
There are also 24 different muscles in each of your arms (including your hands) that are responsible for the variety of movements we can do using our arms.
While humans can live without their arms, they’re still an important part of our body.
As we’ve mentioned before, we spend a lot of our time grabbing things: our phones, doorknobs, food, toilet paper, clothes, etc.
We also use our arms subconsciously! Like, for example, when we try to protect ourselves during a fall or when we cross our arms while we’re talking to someone we’re not quite fond of.
This body part that starts with A is a big part of our body language, and as such, it certainly deserves its place on this list.
Our arteries provide oxygen to our cardiovascular system.
As such, they’re a crucial part of the human body.
In fact, if you accidentally end up cutting one of your arteries, you could bleed to death.
There are more than 20 large arteries in our body, and they all branch out into smaller arterioles throughout our entire body.
Most of our organs need oxygen to function, so without our arteries, we simply wouldn’t be able to live.
If you’ve ever seen a picture of the human cardiovascular system before, you’ll have to agree with how impressive it all is.
It’s a very delicate system – every capillary plays an important part in the human body.
Again, our most vital organs wouldn’t be functional without the help of our arteries.
Because of that, we wouldn’t be wrong to say that arteries cause our heart to beat.
They’re made out of three different layers, all of which have their functions and are equally important.
If you’re interested in learning more about the structure of arteries, you can do so online – many websites and textbooks are covering the topic in detail.
Even though there’s a misconception going around that only men have Adam’s apples, they’re actually a structural part of the human body.
It’s located at the front of the neck, and it’s much more prominent in men, mostly due to higher levels of testosterone.
Some girls can also have a visible Adam’s apple, but it’s not very common.
Either way, it’s an area of the thyroid cartilage that protects our vocal cords from external damage.
In popular culture, it’s commonly associated with masculinity and what’s considered to be a modern perception of “manliness”.
However, as we’ve already talked about before, not only men have prominent Adam’s Apples.
The scientific term used for Adam’s apples is called laryngeal prominence, but it’s rarely used outside of scientific circles.
The colloquial term was probably created according to the famous Bible story about Adam and Eve.
In the story, Adam eats the forbidden fruit which then gets stuck inside his throat. It then “got passed down” to all other men to be a reminder of the First Sin.
Be it as it may, the organ has an important protective role in our body, and as such, it certainly deserves its spot on this list.
Ankles are an incredibly important part of our feet’s bone structure.
They allow smooth movement of our legs and are incredibly important for posture and balance.
If you’ve ever broken an ankle, you probably know how difficult it is to get back to normal functioning.
In essence, ankles are joints consisting of three different bones: talus, tibia, and fibula (which are located in the leg).
Every single bone that’s located in the ankles has its unique function.
Without them, walking and running wouldn’t be possible.
As such, ankles make an extremely interesting body part starting with A.
We can also call them jumping bones or the talocrural region (scientific).
The word has Germanic and Norse origins, and it’s defined as a bone that connects the leg to the foot.
It’s certainly an interesting part of the body – we could spend pages explaining its importance, and it probably wouldn’t be enough.
The appendix is a small tube connected to the large intestine.
Its role in the human body is unknown.
In fact, many people have to remove it due to appendicitis, which is an inflammatory disease that commonly affects the organ.
The condition is extremely painful. Since the appendix doesn’t have an important role in our digestive system, the easiest way to deal with it is via removal surgery.
The word itself comes from the Latin appendix, which can mean attachment or addition.
Either way, it’s one of the most interesting parts of our digestive systems.
It’s just around 5cm in size, and it seemingly doesn’t do much for our bodies.
Still, it’s there and it’s a very unique part of the human body.
As such, it’s certainly worth learning about!
If you’d like to know more about the appendix, you can do so easily by doing your online research.
There are a plethora of interesting facts about the organ just waiting for you to learn them out there!
Remember all of those arteries we’ve talked about before?
Well, the largest, and the most important one in the human body also starts with the letter A!
The aorta ensures your blood gets to every part of your body, excluding the lungs.
Without it, most of your organs wouldn’t be able to get the oxygen that they need to function properly.
The plural versions of the word are aortas and aortae – both are right.
The word itself comes from the Ancient Greek ἀορτή, which translates as arteries connecting to the heart.
As you can probably guess, without this big artery, there would simply be no life.
The typical size is around 3cm, which doesn’t sound much at first, but when you compare it to other blood vessels traveling throughout the body, it’s actually quite impressive.
It starts in the left part of the heart, from where it goes all the way to the stomach.
Once it reaches the abdominal area, it branches out into two smaller arteries, responsible for transporting blood throughout the rest of the body.
