A&P Ch 19.1-19.3 - Blood functions, composition & Plasma

By helping to maintain pH and body temperature, blood functions in the maintenance of .

homeostasis

Blood is comprised of cells and cell fragments, together called "formed elements", suspended in a liquid matrix called blood .

plasma

albumin

An adult patient is brought into the emergency room of a local hospital. The EMTs report the patient lost about 300 cc (cubic centimeters or milliliters) of blood. Is this life-threatening? a. Yes, 300 cc represents about 1/3 of the blood's volume. b. No, most adults have 4-6 liters of blood so a loss of 300 cc would not be life threatening. c. Yes, 300 cc represents about 1/6 of the body's total blood volume of 2 liters. d. No, most adults have more than 7 liters of blood so a loss of 300 cc would not be life threatening
