Bone marrow is the flexible tissue in the interior of bones. In humans, red blood cells are produced by cores of bone marrow in the heads of long bones in a process known as hematopoiesis. On average, bone marrow constitutes 4% of the total body mass of humans; in an adult having 65 kilograms of mass (143 lbs), bone marrow typically accounts for approximately 2.6 kilograms (5.7 lb). The hematopoietic component of bone marrow produces approximately 500 billion blood cells per day, which use the bone marrow vasculature as a conduit to the body's systemic circulation. Bone marrow is also a key component of the lymphatic system, producing the lymphocytes that support the body's immune system.
Bone marrow transplants can be conducted to treat severe diseases of the bone marrow, including certain forms of cancer such as leukemia. Additionally, bone marrow stem cells have been successfully transformed into functional neural cells, and can also potentially be used to treat illnesses such as inflammatory bowel disease.
Broken by
The empty evening
Wondering when it will be
All right again
Waiting patiently
For the tables to turn
Watching you
Go through your moves
My hand is out
You leave me
Standing there helplessly
Until the tables turn
You ask for me, you call for me
I know how it feels
Don't you think I know
You can stand alone?
Just like I did
Until the tables turned
Until the tables turned
The street is dark
But it's my best friend
Wait for the chance
To see you again
I'm waiting patiently
For the tables to turn
I could be wrong
But it might be right
I couldn't stand another night
Just waiting endlessly
For the tables too turn
You ask for me
You call for me
I know how it feels
Don't you think I know
You can stand alone?
Just like I did
Until the tables turned
Until the tables turned
Turn pages in a book
Turn faces with a look
Turn moments back in time
To when you were mine
You ask for me
You call for me
I know how it feels
Don't you think I know
You can stand alone?
Just like I did
Until the tables turned
Until the tables turned
