osteocytes and oxygen?

An osteocyte, a star-shaped cell, is the most abundant cell found in bone. Once osteoblasts become trapped in the matrix they secrete, they become osteocytes. Osteocytes are networked to each other via long processes that occupy tiny canals called canaliculi, which are used for exchange of nutrients and waste. The space that an osteocyte occupies is called a lacuna (Latin for a pit). Their main function involves maintaining the bone tissue.

Erythrocytes are red blood cells. They are made in bone marrow.

Cartilage is a bluish white rubbery tissue found in human beings and animals that have backbones.  It cushions bones against shock and prevents them from rubbing against one another.  It also makes an elastic framework for the ear and respiratory passages.  \n\nBone tissue contains three kinds of cells:  osteocytes, osteoblasts, and osteoclasts.  Osteocytes are cells that lie deeply in a mixture of protein fibers and hard bony tissue.  Osteoblasts form this mixture by laying down new fibers and depositing bone.  Osteoclasts break up the mixture where the bone needs to be remodeled during growth.  About 2/3 of the weight of bony tissue is made up of mineral matter, mostly calcium and phosphorus.  The rest is organic matter, mostly collagen, which is a fibrous protein.

Is this a test question you have to answer?  Increased oxygen provides the "fuel" for your body to function effectively.  Exercise and increased respiration increase blood circulation, providing more nutrients to reach the cells and more waste to be filtered out.  From these basic processes, many other benefits follow.  I'd have to think harder to give you more details - what are you trying to acheive?

Calcium is in the second column of the periodic table, meaning that it has two electrons in its outermost s-shell.\n\nThat means that as an element, it really "wants" to get rid of those two electrons.  So it's going to "try" to be a 2+ ion.\n\nLikewise, Oxygen is in column 6, meaning it has 6 electrons in it's outermost p shell.  Meaning it "wants" to gain 2 electrons to fill up its p-shell.  So it's going to try to be in molecules where it can share two electrons with other atoms.

Here is an interesting fact.  The interior of our bones are lined with copper atoms.\nResearch it, its true.

The spongy part inside of a bone is marrow. This substance creates new blood cells as the old blood cells die.
