ANATOMY & PHYSIOLOGY
pt 2
,CHAPTER ONE:
THE BLOOD
, The Cardiovascular System
Transportation:
- nutrients Subdivisions
- gases (O2, CO2) - cardiovascular system
-
- metabolic wastes - lymphatic system
- heat
- biochemicals
Cardiovascular system
- a series of tubes (the blood vessels) filled with fluid (the
blood) connected to a pump (the heart)
Blood
Functions:
• transportation
• regulation of:
- pH (buffers)
- body temp (constriction/dilation of surface vessels)
- ICF volume (dissolved ions and proteins)
• protection (WBCs, antibodies)
, Physical characteristics of blood
- 5-6L in adult male
- 4-5L in adult female
- 8% of total body weight
- more viscous than water
- temp = 38 degrees celcius
- pH = 7.35 - 7.45
