Made of three parts heart, blood and blood vessels. | Cardiovascular system |
Body contains 5 liters(L). | blood |
Made of cell, cell parts and plasma(the fluid part of the blood). | blood |
Most abundant cells in the body. | red blood cells |
Contains Iron(Fe) and O2 bonds to the FE. | red blood cells |
b/c. they are flat there is more surface area to carry more O2. | red blood cells |
Made in bone marrow. | red blood cells |
Contain hemoglobin which makes cells red and transport oxygen(O2). | red blood cells |
Destroy pathogens-bacteria, viruses and other microscopic particles that make you sick. | white blood cells |
Some engulf pathogens. | white blood cells |
Some release antibodies which destroy pathogens. | white blood cells |
Some engulf body cells that are dead or damaged. | white blood cells |
Made in bone marrow. | white blood cells |
If the cells are lacking in iron not as much of this will be transported in the body. | oxygen |
Only live 5 – 10 days. | platelets |
Clump together when there is a cut less blood is lost. | platelets |
Size of your fist. | heart |
Pumps oxygen poor blood to the lungs and oxygen rich blood to the body. | Heart |

Chemicals on surface of RBC. | antigens |
Chemicals in plasma that bind to antigens not found on their RBC’s. | antibodies |
Has A antigens and B antibodies. | blood type A |
Has B antigens and A antibodies. | blood type B |
Has AB antigens and not antibodies. | blood type AB |
Has no antigens and AB antibodies. | blood type O |
Its RBC’s do not have antigens so recipients’ blood will not attack it. | Universal donor Type O |
B/C they do not produce antibodies against any antigens on the donor’s blood cells. | Universal Recipient Type AB |
