The blood (including the straw-coloured fluid, plasma) is made up of roughly 45% red blood cells. This is what gives it its colour. The amount of platlets and white blood cells is negligable in the scheme of things. Without red blood cells the blood would appear yellow / orange. Hope this helps!
because it is iron based. I've heard that lobsters have blueish blood because it is based on copper.
Hi
Human blood is red due to the existence of a pigment called hemoglobin. hemoglobin contains more of iron. If a person suffers from anemia, it means that the iron levels have depleted thereby reducing the hemoglobin levels. Anemia leads to weakness, paleness.

Why do Humans Die of Old age?Science tells us that our bodies have the ability to stay alive forever by having our cells replacing themselves all the time. So why does that process stop?

We all know how to recognize life, and death. I have heard that modern medical science does not understand why we age and die. Cellular structure and reproduction "should" theoretically go on and on. So why does it not?

Why/How do parents let their children get overweight?Granted it's not my place to judge but it bothers me when I see an overweight parent walking with an overweight child. I feel bad for the child. Why and how does a parent allow this?
