How the Heart Works

To better understand what heart disease is and what icauses heart disease, it helps to first know how the heart operates. The heart is like a pump. About the size of one’s fist, this muscular organ is located at the left center of the chest. The heart is divided into two parts, its left and right side. Having these two parts prevents high oxygen content blood from mixing with the low oxygen content blood or “blue blood.” This blue blood will return to the heart after being circulated through the body.
The heart also has some electrical wiring that allows its constant beating to continue. High electrical impulses start in the right atrium and will travel through the pathways leading to the ventricles, which prompt the signal for pumping. This system allows the heart to beat in a normal and coordinated rhythm which also keeps blood circulation ongoing. This constant exchange of blood keeps people alive.

How Bones Grow in Body

When you were a baby, you had tiny hands, tiny feet, and tiny everything! Slowly, as you grew older, everything became a bit bigger, including your bones. A baby's body has about 300 bones at birth. These eventually fuse (grow together) to form the 206 bones that adults have. Some of a baby's bones are made entirely of a special material called cartilage (say: kar-tel-ij). Other bones in a baby are partly made of cartilage. This cartilage is soft and flexible. During childhood, as you are growing, the cartilage grows and is slowly replaced by bone, with help from calcium. By the time you are about 25, this process will be complete. After this happens, there can be no more growth — the bones are as big as they will ever be. All of these bones make up a skeleton that is both very strong and very light. more...
