11. End Show 37–2 Blood and the Lymphatic System Slide 11 of 34 Copyright Pearson Prentice Hall Blood Plasma The body has 10 pints of blood. About 45% of blood volume is cells. The other 55% is plasma—a straw-colored fluid. Plasma is: 90% water 7% proteins 3% gases, salts, nutrients, hormones, wastes Blood Plasma

13. End Show 37–2 Blood and the Lymphatic System Slide 13 of 34 Copyright Pearson Prentice Hall Plasma proteins are divided into three groups: albumins - regulate osmotic pressure. globulins - fight viral and bacterial infections. fibrinogen – helps clot blood. Blood Plasma

14. End Show 37–2 Blood and the Lymphatic System Slide 14 of 34 Copyright Pearson Prentice Hall The Lymphatic System: The lymphatic system collects fluids lost by the blood and returns it. The fluid is known as lymph. Lymph nodes filter out diseases. The Lymphatic System
