Muscle,Bone,Skin



The muscles, bones, and skin are the main components of structure in the human body. These three things allow you to carry out everyday tasks that are necessary for your survival. MBS are capable of functioning under so much pressure--you'll be surprised by these facts, and you'll never take MBS for granted again! media type="youtube" key="TIZ8VvrW4i0" height="344" width="425" align="center"

Think about this: if the bones in your body suddenly disappeared, your body would be reduced to a messy, blob-like pile of organs. Bones give you the shape and structure your body needs in order to function and do daily tasks such as reading a book or running a marathon. Your femur bone alone needs to withstand 1200 pounds per square inch to just take a walk. If you were jumping, the pressure would increase dramatically--your bones are stronger than you think. As small as they can be, engineers have exclaimed that they are works of wonder seeing that their small and intricate shapes can be so powerful and resilient. There are over 200 bones in the adult body, and each and every one is just as important as the other.

However, support isn't the only thing that your bones supply. There are other inner-body functions that the bones carry out. The bones of your body are responsible for keeping all the other organs inside your body in position. If not, the organs would be all over the place; it would be impossible for them to function in an organized manner. Bones also contain marrow where white and red blood cells are produced (take //that//, Cardiovascular!), store minerals and are the growth factor of your body. If your bones grow, it means you yourself are growing.

Who wants to have tickets to the gun show? Why everyone, of course! Muscles not only give kudos to the attraction factor, but also give your body power and motion. The muscles can contract to create force which is used to move the organism itself of the organs within. For example, swallowing your food is caused by contractions of the esophagus that carry your food down to the stomach. Muscles guide the organs in their processes, and the most important muscle is closer than you think: your heart!

Love the skin you're in--it makes you different from everyone else. Did you know that everyone would be 99.9% identical if you didn't have skin? The skin on the outside layer is specific to each person making them look different and unique to everyone else. The skin also is a form of protection for your body because it keeps harmful bacteria out as well as UV radiation. The cells on the outer layer of the skin can divide and reproduce very quickly to maintain that wall of protection.

The skin contains three layers: the epidermis, the dermis, and the subcutis. These three layers are what give you the protection, but that's not all. The skin also regulates salt concentration by sweating. This process also allows the body to cool off because the sweat evaporates on your skin to give you that cool feeling. The skin also absorbs molecules through the pores to give the body what it needs. Oxygen, nitrogen and carbon dioxide can diffuse into the epidermis in small amounts. In addition, medicine can be administered through the skin, by ointments or an adhesive patch, such as the nicotine patch or iontophoresis.
