In anatomy, the left and right common carotid arteries (English pronunciation: /kəˈrɒtɪd/) are arteries that supply the head and neck with oxygenated blood; they divide in the neck to form the external and internal carotid arteries.
The common carotid artery is present on the left and right sides of the body. These arteries originate from different arteries, but follow symmetrical sources. The right common carotid originates in the neck from the brachiocephalic trunk; the left from the aortic arch in the thorax. These split into the external and internal carotid arteries at the upper border of the thyroid cartilage, at around the level of the fourth cervical vertebra.
The left common carotid artery can be thought of as having two parts: a thoracic (chest) part and a cervical (neck) part. The right common carotid originates in or close to the neck, so contains only a small thoracic portion. There are studies in the bioengineering literature that have looked into characterizing the geometric structure of the common carotid artery from both qualitative and mathematical (quantitative) standpoints.
They don’t know,
They won’t see,
They won’t change,
They won’t be,
They won’t love,
They won’t go,
They won’t touch,
So they don’t know,
How much it takes for me to stay awake,
Dodging the poisonous darts you throw with your face,
I try to avoid the dark but it’s hard,
When you let go of me like rose pedals in the front yard,
One card, we play till we pass out,
Used to be my ace, now I’m feeling assed out,
So I back out the front porch,
While you reconsider what you really want more,
Me? Nah, I got a knack at leaving you breathless,
Bringing out the smiles that the angels eat for breakfast,
You deadest on watching me step,
Across a bed of coals just to see which arguments next,
Stress don’t leave when you’re next to me,
I’m my kinder side, you’ve got the best of me,
So let’s act like we don’t care,
There’s a moonlit path outside,
We should go there,
And make the clouds part,
I’ll grab you by the wings and you can guide me through the wild part,
Then that smile starts to speak,
Telling me why it’s been gone for weeks,
If it was all on me,
We’d get together right now,
Debate our different lifestyles,
And this is how it might sound,
They don’t know,
They won’t see,
They won’t change,
They won’t be,
They won’t love,
They won’t go,
They won’t touch,
So they don’t know,
What it’s like to wake up to a princess,
Eyes like a lighter, you spark my interest,
We invest too much to be selective,
Ingest solitude then redefine my objective,
Cause that necklace really makes me want to choke you,
Kill all the demons that grab your soul and hold you,
If I could mold you to just my shape,
I’d change absolutely nothing,
Mm that’s great,
Now that we got it all out on the table,
Come here baby girl I want to fuck with your halo,
Grab you by the hips and settle the score,
