Red Blood Cells perform the most important duty in the human body. They carry oxygen from the lungs to all parts of the body and remove waste that the body doesn't need (Carbon Dioxide) to the lungs which we breath out. Without the Red Blood Cells, our body will slowly die. Over time, the Red Blood Cells get worned out and eventually die off but the bones in our body continue to produce more blood. The average life cycle it has is 120 days.
As our bodies continue to produce more blood, it is safe for a adult to donate blood to help those who are in need of it or for emergencies. Once donated, the donator will feel light headed due to the loss of oxygen-rich red blood cells and blood sugar. This is not a worry as the body will quickly stabilize itself.

White Blood Cells are provided to fight off infections like viruses, bateria and fungi. They are always on the lookout for diseases and when a germ appears, they can attack in two ways.
1. Produce protective antibodies that will overpower the germ.
2. Surround the germ to devour it.
The white blood cells have a short life span, living up to a few days or a few weeks. A drop of blood can contain anywhere from 7,000 to 25,000 of white blood cells at the time. If the drop contains 50,000 white blood cells, the person will have the symptom Leukemia which is a cancer in the blood.

Antibodies are produced by the white blood cells to help weaken and overpower infections that are a threat to the immune system. Antibodies are produced in the blood stream to find an infection that's in the body or search to make sure there is no infections around. The life span of the antibodies is a few weeks.
