Coloring Page Communities – Some websites offer very basic coloring pages for kids that can be printed off and colored. You save a great deal of money. This is a fantastic thing you can do today to bond with your son and I really recommend it.
The body contains trillions of cells, the fundamental unit of life. At maturity, there are roughly 30 –37 trillion cells in the body, an estimate arrived at by totaling the cell numbers of all the organs of the body and cell types. The body is also host to about the same number of non-human cells as well as multicellular organisms which reside in the gastrointestinal tract and on the skin. Not all parts of the body are made from cells. Cells sit in an extracellular matrix that consists of proteins such as collagen, surrounded by extracellular fluids. Of the 70 kg weight of an average human body, nearly 25 kg is non-human cells or non-cellular material such as bone and connective tissue.
