Question | Answer |
---|---|
Cardiovascular System | - Transports materials to and from your cells. - Made of three parts: heart, blood, blood vessels. |
Blood | - Body contains 5 Liters (L) - Made of cells, cell parts and plasma (the fluid part of the blood) - Red + White blood cells. |
Red Blood Cells | - Most abundant cells in the body. - Contain hemoglobin which makes cells red and transports oxygen (O2) - Contains Iron (Fe) and O2 bonds to the FE. - Made in bone marrow |
White Blood Cells | - Destroy pathogens (bacteria, viruses, and other microscopic particles that make you sick) - Some WBC's engulf pathogens. - Some WBC release antibodies which destroy pathogens - Some engulf body cells that are dead or damaged. - Made in the BM. |
WBC's contain more _____? | Lysosomes because they are responsible to attacking and destroying foreign particles. Lysosomes contain digestive enzymes. |
Platelets | - Only live 5-10 days. - Clump together when their is a cut so less blood is lost. |
Antigens | Chemicals on the surface of Red Blood Cells |
Antibodies | Chemicals in plasma that bind to antigens not found on their Red Blood Cells. |
Types of Blood | A, B, AB, O |
"A" blood type has... | A antigens and B antibodies |
"B" blood type has... | B antigens and A antibodies |
"AB" blood type has... | AB antigens and NO antibodies |
"O" blood type has... | NO antigens and AB antibodies |
Universal Donor | Has "O" blood type b/c it's RBC's do not have antigens, so the recipient's blood will not attack it. |
Universal Recipient | Has "AB" blood type b/c they do not produce antibodies against any antigens on the donor's blood cells. |
