A man's blood is a reddish liquid. It contains plasma, white particles and red particles. Blood contains about 5 percent of plasma. Plasma blood droplets contain about 10 million red blood cells. Because of this it looks red.
The blood contains white particles to fight the infectious bacteria. The proportion is only one percent. But its role in the immune system is important. The whites live for 3 hours and then become new. The main purpose of the red cells is to give the body oxygen to get carbonandoxide. The red particle that lasts 3 days provides oxygen and energy to the body. New additions are being replaced by the destroyed ones. The cavities between the bones are added to the blood by hundreds of billions of new scars.
The white and blood cells in the blood are destroyed in the spleen. The spleen collects and destroys other toxic and harmful substances in the gall bladder. In addition to the red and white particles in the blood, there are also platelet particles.
