Document Summary
A liquid connective tissue consisting of cells and extracellular matrix. Red blood cells, white blood cells, and platelets. Plasma: extracellular matric: clear, light yellow fluid. Adults have 4 to 6l of blood. Erythrocytes: heaviest and settle first, 37% - 52% total volume. White blood cells and platelets: 1% total volume, buffy coat. Plasma the remainder of volume: 47% - 63, complex mixture of water and variety of solutes. Plasma proteins: albumins: smallest and most abundant transport, globulins (antibodies) transport, clotting immunity, fibrinogen clotting. Nitrogenous compounds free amino acids from dietary protein or tissue breakdown. Glucose, vitamins, fats, cholesterol, phospholipids, and minerals. Na+ makes up 90% of plasma cations. Identical to plasma except for the absence of fibrinogen. Primary function carry oxygen from lungs to cell tissues, pick up co2 from tissues and brings to lungs.
