Helps maintain osmotic pressure
What Is the function of globulins?
Transport lipids and vitamins

Neutrophils- most
Basophils- least
What is the function of neutrophils?
eat small particles and bacteria

Release histamine to increase blood flow
What is the function of monocytes?
eat large particles
What is the function of lymphocytes?
Provides immunity
What is hemostasis?
The stoppage of bleeding
What order does blood coagulation, blood vessel spasm and platelet plug occur during hemostasis?
Blood vessel spasm
Platelet plug formation
Blood coagulation
What is a thrombosis?
A clot that forms abnormally in a vessel
What are antigens?
Protein molecules on the surface of a cell membrane
What are antibodies?
Proteins that circulate in the plasma
What is agglutination?
Clumping of red blood cells after a bad Transfusion caused by antigens binding with antibodies from transfused blood
What antigens and antibodies does type A type B type ABand type O have? What blood types can the receive from?
Type A- A antigens and anti-B antibodies
*receive from A or O
Type B- B antigens and anti A antibodies
* receive from B or O
Type O- neither A or B antigens but both A and B antibodies
* receive from O
Type AB- A and B antigens and no antibodies
*receive from A,B,AB or O
How are blood types negative?
Th antigen isn’t present
Who is the universal recipient and the universal donor?
Recipient- AB
donor- O
What are the functions of blood?
Delivers oxygen and nutrients to cells, transports waste from cells and maintains homeostatis
What are thrombocytes?
Platelets
