Question

How is blood made in your body?

Answer 1

The body must produce the liquid part of blood, called plasma, and the cells that float in it. Plasma is made mostly of water and salts that we absorb through our digestive tracts every day. Its job is to deliver nutrients and water throughout the body. Ninety-nine percent of the blood cells floating in plasma are red blood cells, which carry oxygen from the lungs to the rest of the body and give blood its red color. The average life of a red blood cell is four months.

Answer 2

Whenever you inhale your lungs fill with oxygen. That oxygen goes to your heart and acts as a fuel to make blood. You're heart then pumps it to everywhere in your body through your veins and takes back the used blood. When returned to the heart, the oxygen refreshes the red blood cells to make them usable again! When you exhale, you get rid of the Carbon Dioxide, which is basically used up oxegen, so it's useless. After you exhale, you inhale again and the process starts over again!
