Who was Dr. Charles Richard Drew Have you ever heard of Dr. Charles Drew? Do you know anyone who has donated blood? If you know anyone or have had a blood transfusion, you have Dr. Drew to thank for his work in enhancing blood storage methods and raising the quality of blood transfusions.

Blood Blood carries cells, dissolved nutrients, hormones, oxygen, carbon dioxide and urea around your body. It is a transport system. It is a connective tissue made up of different types of cells Red blood cells (erythrocytes) White blood cells (lymphocytes and phagocytes) Platelets And a liquid called plasma.
Blood Cells Red blood cells have a protein called hemoglobin which carries oxygen to cells and removes carbon dioxide. White blood cells destroy pathogens which cause diseases in the body. There are two types of white blood cells. Lymphocytes produce antibodies. Phagocytes engulf and destroy pathogens. Platelets release chemicals to make blood clot when you get cut making a scab.
Plasma Plasma is an important component of blood, but it is not a cell. It is a liquid. Image: https://my.clevelandclinic.org/health/body/22865-plasma
Blood Comes in Different Types The different types of blood were discovered by Dr. Landsteiner who one the Nobel Prize in Medicine in 1930. Dr. Richard Lewisohn contributed to making transfusion safer. It often take many scientists to solve problem.

ABO Blood Type Blood is typed based on the proteins (antigens) on the surface of red blood cells. The blood types are: Here is a quick explanation: Amoeba Sisters - Blood Types Video O A B AB And each can be + or -.
Can you predict blood type? Blood type is a codominant trait and you can use a Punnett Square. YES! Ameoba Sisters Blood Types and Punnett Squares
Once you know the blood type, you can determine who can receive which blood A blood transfusion is when blood from one person is given to another. If you get the wrong type of blood, it can be deadly.

Review There are often several scientists who help with a discovery. Some scientists work with blood, blood typing, storage of donated blood and blood transfusions. There are four parts of blood: red blood cells, white blood cells, platelets and plasma. There are four blood types: A, B, AB and O. Blood can also be + or Rh. Blood types are important when performing a blood transfusion.
