“What is the tissue that fills the center of bones?”


Bones are quite sturdy structures. A cubic inch of this material can sustain the weight of five pickup trucks. However, what exactly is at the center of bones and what functions do they perform? Well, it turns out that a quite peculiar bone marrow is what fills the interior of bones. Bone marrow is a soft and spongy in nature, and it contains stem cells. Stem cells are analogous to workers that have not yet been given a function. These cells are nascent and have no use, but they can be specialized to perform become cells that create new parts of the body such as cartilage, muscles, blood cells, and even other bones! Bone marrow is vital for the health of a human body.
