Document Summary

Transport mechanisms: across cell membrane, across capillary wall lungs. Ancient chinese medicine- blood linked to energy flow. Ancient greece advocated bleeding as treatment for many diseases. Medieval western medicine blood inhabited by good and evil spirits. It comprises both ecf (plasma) and icf (inside blood cells) May be studied in vivo and in vitro. It is that percentage of blood volume that is occupied by red blood cells. Ht = height of erythrocyte column x 100. Blood volume = ~7- 8 % of body weight. If hematocrit (% of blood volume occupied by rbcs) is 45%, Composition of plasma (similar to that of isf) May be approximated by physiological saline: 0. 9g/dl nacl. , (po4: > 90% water, na+, k+, (ca++, mg++) Cl-, hco3: glucose, amino acids, lipids, o2, co2, proteins (colloids) = 7g% Separating plasma proteins: differential precipitation by salts, sedimentation in ultracentrifuge. Electrophoresis fractionation method based on movement of charged particles along a voltage gradient.
