 Blood  Erythrocyte  Hemoglobin  Leukocyte  Platelet  Plasma  Hematopoiesis  Blood Transfusion  Blood Type  Antigen  Antibody  Blood Donation

There are 5-6 liters in a grown male It is about 8% of your body weight

 AKA: Red Blood Cells  Donut shaped! (But there’s not a hole in the middle, it’s just flattened out)  Makes up 45% of all blood  Main job: transport oxygen from the lungs to the rest of the body  Only last for 4 months, then they are removed from the body by the liver  Contains hemoglobin

 Protein on the erythrocyte that holds the oxygen molecule › There are 250 million hemoglobin molecules on EACH erythrocyte… › Each hemoglobin molecule can carry 4 oxygen molecules…  250 million x 4 = 1 billion oxygen molecules can be carried by 1 erythrocyte

 Makes up 1% of all blood  Protects body, fights infection  Can leave the blood vessels to hunt down and destroy infections!  Leukocyte levels can be measured to determine if person is sick  If you are sick (fighting infection), your body makes a lot of leukocytes to win the fight… so more leukocytes = probable infection AKA: White Blood Cells

 Makes up 1% of all blood  Pieces of cells  Clots bleeding

 Makes up 53% of all blood  Fluid part of blood › Mostly water

 Blood cell formation (making blood cells)  Happens in: › the ends of long bones in red bone marrow › flat bones like skull and pelvis › ribs & sternum

Blood Transfusion – the transfer of blood from one person to another Why would someone need to receive blood from another person?  Certain diseases like Sickle Cell Anemia  Cancer, for example Leukemia  Surgeries like organ transplant or Open-Heart Surgery  Open-Heart surgeries can require up to 10 pints of blood

There are 4 blood types: A = 40% B = 11% AB = 5% O = 44%

1 Antigens are little proteins on the outside of red blood cells 2 Antibodies are made for any antigens you don’t have on your red blood cells 3 If you put blood in your body, and you have already made antibodies for those antigens, your body will start attacking 4 This attacking can lead to blood clots, which can cause heart attacks and strokes

To Be Able to Donate, You Must Be: At least17 years old At least 110 pounds Healthy You Are Not Allowed to Donate If You: Have used IV drugs (like heroin) Have hemophilia Have HIV/AIDS Have hepatitis Have or have had cancer
