The living framework

Most of your body is soft material,such as muscle,and soft organs,such as the brain or stomach.Without stomach from your 206 skeletal bones,you would be shapeless mass,like a jellyfish.Some of the skeletal bones also have a 2nd important job-they protect other organs of the body. The hard skull bones,for example,protect your all-important brain.Your heart and lungs,which are also vital organs,are protected by the breastboned and by the cage formed by the ribs.The skeleton is a framework,but it's really very different from the framework of a building.Think of how much u've grown since u were born.And you aren't through growing yet!can this rigid skeleton grow with you?indeed it can!Bone is very much alive.Like the other parts of your body,bone has blood vessels and nerves,but it doesn't out as bone.Did somebody ask how it does start out?Well,stay here,i will tell this fascinating history in the next post..thanks!!

The skin

Hye,2nd posting,let's begin our look at the part of the body by looking first at the skin.We all know what hands and eyes are for,but what does the skin do? It is easy to see that the skin is a cover for the inner parts of the body.But like many other organs of the body,it has several jobs or functions.The skin is an organ that senses changes around you,and helps to keep the body temperature steady.The skin is a barrier against germs.It also removes some substances from the body and stores others temporarily.
We really should talk about ur skins,for you have two of them.The outer skin that u can see and touch is the epidermis.it is skin in which the living material has been replaced by a hard substance called keratin.as u grasp,touch,rub and wash,the cells of the epidermis are worn away,however,for the lower skin or dermis constantly produces new cell. These called fresh epidermis.
