Resource summary

Fluid in Body
1 Function
1.1 Prevents sudden temperature changes
1.2 Cushions body organs e.g. CSF and CNS
1.3 Solvent = allowing electrolytes to ionise
1.4 Reagent in many chemical reactions
1.5 Act as a transport medium e.g. blood
1.6 Lubricant e.g. mucus
2 Physiology
3 Fluid Compartments
3.1 Male
3.1.1 40% solid
3.1.2 60% fluids
3.1.2.1 2/3 = Intracellular fluid
3.1.2.2 1/3 = Extracellular fluid
3.1.2.2.1 80% Interstitial fluid
3.1.2.2.2 20% Plasma
3.2 Female
3.2.1 45% solid
3.2.2 55% fluids
3.2.2.1 2/3 = Intracellular fluid
3.2.2.2 1/3 = Extracellular fluid
3.2.2.2.1 80% Interstitial fluid
3.2.2.2.2 20% Plasma
4 Relation to Lymph flow (Factors that increase rate)
4.1 Rate of lymph formation
4.2 Contraction of skeletal muscles = compress lymph in vessels = pushing it
4.3 Valves that prevent backflow
4.4 Rythmic contraction of lymph vessels
4.5 Venturi effect = blood flow , drawing lymph into blood vessel where 2 meet
4.6 Respiratory pump --> inhalation, pressure in thoracic cavity is lower that the one in abdominal. Effect of drawing air into lungs and pulling lymph upwards inside lymph vessels
4.7 Gravity
