The heart is made of muscle cells which pump the body’s blood throughout our lives from dawn to dusk and then from dusk to dawn. They function on their own and beat a steady rhythm by contracting and relaxing.
In a normal healthy beating heart the cells are active once a second or a hundred thousand times a day, two billion times a life or more.
The little grey cells that make up your mind are primarily neurons. You have approximately 100 billion of them in your head! All a single neuron can do is flash a small signal on to its neighbors. But working together, they bestow upon us action like an angel, and apprehension like a god.
Or is it our thoughts that animate them? Cogito ergo sum.
The skin has three layers. The top layer, or epidermis, is made primarily of tough keratinocyte cells that ward off everything from pathogens to blunt objects. The epidermis contains pigment-producing melanocyte cells that give your skin its color.
Beneath the epidermis, the dermis layer contains the blood vessels that help regulate temperature and the nerves that allow you to feel heat and touch.
Of the major internal organs, the liver is the only one that can regenerate ? from as little as 25% of its mass.
The liver is also the largest internal organ (the skin is regarded as the largest organ overall) and was once thought to be the source of the four personality-governing humors: blood, yellow bile, black bile, and phlegm.
Beta Cell (Insulin)
Pancreatic beta cells produce the insulin that helps regulate the level of glucose sugar in the body. When blood sugar levels rise, beta cells release insulin which causes fat and muscle cells to begin absorbing the excess sugar.
However, if the beta cells are damaged, insulin production can become impaired. Type 1 diabetes is believed to be the result of an autoimmune response where the body?s own immune system attacks the cells and destroys them.
