| C. | Contraction of the smooth muscle in the thoracic vessel walls prohibit lymphatic vessels from pulsing rhythmically and, thus, helps to keep lymph from moving from one valved segment to the next. |

- Which choice best explains how the forces of osmotic pressure and hydrostatic pressure work to maintain a balance of fluid moving into and out of the capillary?
| A. | Osmotic pressure tends to promote diffusion of fluid out of the plasma, but hydrostatic pressure causes a larger, inwardly directed force at the arterial end of a capillary; the flow of fluids into plasma is controlled by both of these pressures. |
| B. | If the lymphatic system operates normally and the osmotic and hydrostatic pressure gradients remain relatively constant, there is no net loss of blood volume resulting from capillary exchange. |
| C. | If the lymphatic system operates normally and the osmotic and hydrostatic pressure gradients fluctuate greatly, there is no net loss of blood volume resulting from capillary exchange. |
| D. | The weaker, inwardly directed forces at the arterial end of a capillary drive fluids out of the blood vessel and into the surrounding interstitial fluid, producing a net loss of blood volume. |
