Ojective 19: Whats Blood Made Of ???

So blood isn't just blood, well I mean yea it is but not like I use to think it was. Now I see that it's not just this red liquidy stuff that comes out of me when I cut myself. Blood is made up of all this different stuff. 55% of blood is made of this stuff called plasma which is said to look straw clolored. Then there are the red blood cells which make up 45% of the blood. Then between the two, there is a layer called the buffy coat and it only takes up less than 1% of the blood.
