Hemoglobin-Hb or Hgb

Hemoglobin is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues to the lungs. It also contains iron. http://www.medicinenet.com/hemoglobin/article.htm (info) http://www.daviddarling.info/images/hemoglobin.jpg (picture)

Hemoglobin Transportation

The human body needs iron for oxygen transport. That makes Hemoglobin important in the transport of oxygen in our bodies.

How is Hemoglobin related to a successful climb to the top oof Mt. Everest?

Hemoglobin caries oxygen throughout the body which helps

What Does pH Have to do With the Transport of Oxygen By Hemoglobin?

pH is sufficient to cause release of oxygen from hemoglobin at the tissue cells.

Why is the Transport of Oxygen by Hemoglobin a Real-Life Example of Chemical Bonding?

Because iron and oxygen formed and created a chemical bond.

Blood Doping

Blood doping is the practice of boosting the number of red blood cells in the bloodstream in order to enhance athletic performance.

Autologous and Homologous Blood Doping

There are two forms of blood doping: autologous and homologous.

Autologous blood doping is the transfusion of one’s own blood, which has been stored (refrigerated or frozen) until needed.

Homologous blood doping is the transfusion of blood that has been taken from another person with the same blood type.

EPO EPO is a peptide hormone that is produced naturally by

the human body. EPO is released from the kidneys and acts on the bone marrow to stimulate red blood cell production.

An increase in red blood cells improves the amount of oxygen that the blood can carry to the body’s muscles. It may also increase the body’s capacity to buffer lactic acid.

Blood Doping Used In Sports

increase one’s red blood cell mass, which allows the body to transport more oxygen to muscles and therefore increase stamina and performance.

Marion Jones

Marion Jones was caught of blood doping and admits it too.

Marion Jones, is a former world champion track and field athlete. She won five medals at the 2000 Summer Olympics in Sydney, Australia but has since agreed to forfeit all medals and prizes dating back to September 2000 after admitting that she took performance-enhancing drugs.

She also admitted taking steroids before the Sydney 2000 Summer Olympics.

Floyd Landis

Floyd Landis, is an American cyclist, from Farmersville, Pennsylvania, he was disqualified after finishing first in the 2006 Tour de France for a doping offense.

Blood Doping Side Effects

People should stop blood doping. Because, When blood is thickened because of extra red blood cells, you can get blood clots, strokes, and heart attacks. Blood transfusions run the risk of HIV, AIDs, and other blood diseases. Artificial oxygen carriers can cause liver and kidney disease and other problems.
