Body fluids
Body fluids

  • 42 liters of fluid in the average adult

  • INTRACELLULAR inside of cells

  • EXTRACELLULAR outside of cells

  • INTERSTITIAL surrounds individual tissue cells

  • PLASMA-liquid portion of whole blood


Fluid composition

INTRACELLULAR-large amount of proteins and a different concentrations of ions

The total ionic concentrations for the fluids are identical. Must maintain isotonic conditions.

Fluid composition


O 2 and co 2 transport

The most important functions of blood concentrations of ions

98% of the oxygen is transported by hemoglobin in the red blood cells

Oxyhemoglobin-oxygenated form

Deoxyhemoglobin-unoxygenated form

Average person-15 grams of hemoglobin per 100 ml of blood

O2 and CO2 transport


CO concentrations of ions2 tranport:

25% as a carbaminohemoglobin

70% as bicarbonate (HCO3-)

5% as CO2 dissolved in plasma


Chemical transport to the cells

dissolved in the water-based plasma. (ions, amino acids, sugars)

bound to cellurar components. (oxygen, carbon dioxide)

travel as a suspension –colloid (lipids)

Chemical transport to the cells


Chemical transport to the cells1

pass through the capillary wall which acts as a semipermeable membrane

enter the interstitial fluid

finally pass through the cell wall

Chemical transport to the cells


Acid-base balance semipermeable membrane


Respiratory control of blood ph

HYPERVENTILLATION semipermeable membrane

Increaced rate and depth of breathing reduces the CO2 in blood, increases pH.

Respiratory control of blood pH

  • HYPOVENTILLATION

  • Reduced rate and depth of breathing increases CO2 in blood, decreases pH.


Thanks for your attention semipermeable membrane


APLAUS !!! semipermeable membrane

blood – krev

fluid – tekutina

average – průměr

maintain – udržovat

condition – podmínka

lungs – plíce

pass through – projít

depth – hloubka

attention – pozornost

aplaus – potlesk 
