The life span of a platelet is about 1 week because they are used up in blood clotting and they are too simple to carry on much metabolism. Sodium and chloride ions are the most plentiful. Allergies Converted to INsoluble fibrin as blood coagulates Plasma protein concentrations vary little in good health. The albumin to globulin ratio is approximately 2. Protein concentrations decrease due to starvation, liver damage and renal disease.
Albumin serves to increase the osmotic pressure of blood.
In starvation, protein intake is decreased with secondary decreases in circulating amino acids' concentration, which leads to decreased plasma protein levels. Water and electrolytes come into the blood stream following absorption across the gut. Amino acids are absorbed across the gut into the blood stream, as well. Water, electrolytes and amino acids are also released from cells into the blood stream. It lasts until about 2 weeks of age in infants.
