Chapter 19: Blood
● Cardiovascular system components
○ Blood, heart and blood vessels
○ Hermatology: study of blood, tissues and blood disorders
○ Two fluids that obtain Oxygen and eliminate CO2
■ Blood: liquid CT that consists of cells surrounded by a liquid extracellular
matrix
■ Interstititial fluid: bathes body cells
● Functions:
○ Transportation: O2 to the lungs to cells of the body and CO2 from body cells to
the lungs
■ Transports heat and waste products to various organs
■ Transport respiratory gases, nutrients, hormones to and from body cells
○ Regulate body pH and temperature, provide protection to maintain homeostasis
■ Use buffers to convert strong acids/bases to weak ones
○ Protection: can clot to protect excessive loss
■ White blood cells can do phagocytosis
● By blood proteins, antibodies, interferons, and complements
● Characteristics:
○ More viscous than water
○ Temperature: 38 degree Celsius
○ pH; 7.35-7.45
○ 20% of extracellular fluid
○ Volume: 5 to 6 liters (45% cells 55% plasma)
○ Hormones ensure homeostasis in volume and osmotic pressure (e.g.:
aldosterone, antidiuretic hormone, atrial natriuretic peptide)
