    pH: 7.35 – 7.45
    Temp: 38 degrees
    Body weight: 8%
    Average blood volume:
  • M: 5L – 6L
  • F: 4L – 5L
    Functions of blood:
  1. Distribution: blood transports:
     Oxygen and nutrients -> peripheral tissue
     CO2
     H2O, electrolytes, urea -> urine (kidneys)
     Hormones (endocrine glands) -> target organs

  2. Regulation:
     Appropriate body temperature
     pH in tissues buffer systems
     fluid volume in circulatory systems

  3. Protection:
     prevents blood loss (Platelets)
     prevents infection (WBC)
