If Blood Is Red,Then Why Are Veins Blue?

Introduction

We need blood to live. The pump of blood through our blood vessels is called circulation. The cells take the oxygen and nutrients from the blood. The carbon dioxide is transferred to the veins and back to the heart. When the blood is pumped back to the heart, it pumps it to the lungs. Once in the lungs, carbon dioxide is released when exhaled. Then oxygen is entered when inhaled. Blood is always red. Blue light is reflected back into our eyes when we see our own veins.

Opinion

Veins are blue because it is the color sent back when looking at them. Most people think that veins are blue because blood is blue without oxygen. I thought that veins are blue because there could be blue cells  and they could have changed of what you see outside the skin. Overall, veins are blue because of the light bouncing your eye to the vein.

Can Writing Be Art?

Introduction

The writing of an author can be a form of art. The words that are being used is just like art. They use imagination in their words. Cave paintings were used in ancient language which was in the form of art. Those cave painting eventually developed into hieroglyphics. Hieroglyphics were basically were just pictographs which was a form of art and these hieroglyphics was the first alphabet in the world which developed into our modern alphabet we use today.

Opinion

My opinion about this is that all writing is art. Every person has a different form of writing and all is art. Since our alphabet originated from hieroglyphics, all writing is art. This shows that all writing is art. Some people will say that writing is not art. I disagree. According to these facts, this supports my statement of all writing is art.
