Functions of the blood system
(1) Transportation of materials throughout the body
(2) regulates fluid and electrolytes, pH and body temperature
(3) protection via WBCs and platelets
composition of blood
plasma and formed elements
liquid; 55% plasma; straw color; 90% water, 10% solutes
Plasma
plasma without the clotting proteins
serum
proteins found in the plasma at all times
plasma proteins
regulates fluid balance and electrolytes
albumin
WBCs; protection
Globulins
Prothrombin and fibrinogen
clotting proteins
45% of blood composition; RBCs, WBCs, thrombocytes
formed elements
precursors to all of your blood cells
stem cells
most numerous: 4.5-6.0 million
carry o2 via hemoglobin
no nucleus when mature
120 day life span

coagulation
stationary blood clot
thrombus
traveling blood clot or foreign material in the blood stream
embolus
A, B, AB, O; proteins that may or may not be in RBCs
blood types
O-
universal donor
AB+
universal recipient
abnormal clumping of blood cells due to mismatched blood types
agglutination
a protein that may or may not be on RBCs
documented as + positive if present and - negative if not present
