Crash Course Blood

What is the process of blood doping?(From start to finish)

• Before competition, athlete injects store blood back into his or her body to increase number of red blood cells and oxygen. Athlete drains their own blood

  Athlete stores the blood in cool place for later

• Before competition, athlete injects store blood back into his or her body to increase number of red blood cells and oxygen.

  Athlete stores the blood in cool place for later

  Athlete drains their own blood

• Athlete drains their own blood.

  Athlete puts extra chemicals inside the blood.

  Athlete injects the doped blood before competition.

• Athlete drains their own blood

  Before competition, athlete injects store blood back into his or her body to increase number of red blood cells and oxygen.

Some athletes increase the amount of __________________ that can be carried by their bodies through a process called blood doping.

• Protein

• Oxygen

• Amino Acids

• Starch

Blood doping is an illegal process in which athletes increase their bodies’ ability to increase their release of energy by:

• Providing the body with more glucose which means a faster rate of cellular respiration and increased release of energy

• Providing the body with more amino acids which means a faster rate of cellular respiration and increased release of energy

• Providing the body with more oxygen in the body which means a faster rate of cellular respiration and increased release of energy

What system is involved in helping the process of blood doping happened in our body?

• Circulatory System

• Respiratory System

• Digestive System

Why is blood doping very difficult to detect?

• Since the body always contains red blood cells, it is difficult to detect oxygen that is injected into the athletes bloodstream.

• Since the body always contains red blood cells, it is difficult to find evidence that an athlete has injected extra red blood cells into his or her bloodstream

How can scientists detect blood doping?

• By testing the age of the red blood cells in the athletes body

• By testing the chemicals present in the red blood cells in the the athletes body

• By test the amount of oxygen present in the read blood cells in the athletes body.

Doctors use the age of red blood cells to decide whether or not someone was blood doping by noticing...

• If there is more younger aged cells present than aged red blood cells

• If there is more older aged cells present than newly produced cells

• If there is more older aged cells present than newly produced cells

Hemoglobin is the specific part of red blood cells that carry oxygen. Doctors use Hemoglobin levels to decide whether or not someone was blood doping by noticing....

• If an athlete has a hemoglobin level that is higher on the day of a race than it was a week before the race, that provides evidence that the athlete might be blood doping.

• If an athlete has a hemoglobin level that is lower on the day of a race than it was a week before the race, that provides evidence that the athlete might be blood doping.

• If an athlete has a hemoglobin level that is stays the same on the day of a race than it was a week before the race, that provides evidence that the athlete might be blood doping.

When you are at a high altitude with less oxygen, your body makes more…

• Glucose

• Red blood cells

• Oxygen

• Amino Acids

It takes a few weeks for the number of red blood cells to go down when you return to a lower altitude, so the athlete could….

• produces more red blood cells so that more oxygen can be picked up with each breath.

• produces more oxygen so that more red blood cells can be picked up with each breath.

• produces more glucose cells so that more oxygen can be picked up with each breath.
