Blood Flashcards
What part of the composition of blood are formed elements? (Solid part)

What are red blood cells, white blood cells and platelets called?
Erythrocytes, leukocytes, thrombocytes
What’s the function of red blood cells?
Transport oxygen and carbon dioxide

Blood clotting
The formation of formed elements (blood cells) from stem cells is called
Hematopoiesis
How do you determine blood type?
By the antigens on the surface of the red blood cells
Type A blood
Surface= Rounded type A antigen
Plasma= Spikey anti B antibodies
Type B blood
Surface= Spikey B antigen
Plasma= Rounded anti A antibodies
Type AB blood
Surface= Both Spikey A antigen & B antigen
Plasma = none
Type O blood
Surface = no antigens
Plasma = anti A & B antibodies
What’s agglutination?
Clumping of cells, occurs when antibodies of one blood type combined with antigens of another blood type
What’s Rhesus factor?
Blood protein found on the surface of a red blood cell
Rh negative
NO Rhesus antigen on the surface of red blood cells
What’s regurgitation?
Blood flowing backwards due to a valve prolapse
