Plasma and formed cell elemens

straw-colored, liquid part of blood that seperates out at th top

the cells in blood that settle out because they are heavier

• water- 91%
• solutes- 2%
• proteins- 7%

• albumin
• globulins
• fibrinogen
• prothrombin

• Prothrombin
• Fibrinogen

immune proteins (antibodies)

proteins that helps retain water in the blood

is plasma minus the clotting protiens

• RBC
• WBC
• Plateles

Thin layer of WBC's anad platelets that form the top part of the "formed elements"

• RBC's called erythrocytes
• formed in bone marrow
• in formed element
• no nucleus
• reticulocytes
• carry oxygen to cells and carbon dioxide away from cells
• contatins hemoglobin which has iron and give RBCs and blood the red color
• biconcave discs and flexible

young RBCs that have shed nucleus just before they mature

carry oxygen to cells and tissue and carry carbon dioxide away from cells and tissue

• called thrombocytes
• clotting cells
• first step of clotting process where paltelets get "sticky" and clump together to form temporary clot
• not WBC's

clumpin(stickyness) of platelets to form temporary plug until sequence of clotting proteins can act

production of fibrin

X-linked (transmitted by mother) bleeding disorder in which a clotting proteins can act

• called leukocytes
• five catergories
• part of the body's defense system

• neutrophils
• basophils
• eosinophils
• lymphocytes
• monocytes

• most numerous WBC
• phagocytes
• granulocyte

• granulocyte
• involved in allergic reaction
• protects against parasite infections

• granulocyte
• secrete histamine and heparin

• agranulocytes
• involved in production of antibodies (B lymphocytes)
• and direct atack of invading cells (T lymphocytes)

B and T

mature or activated B lymphocytes

• largest WBC
• agranulocytes
• phagocytes (name mmeans largest eater)
• marcrophages when enter tissue
