Question

60. After puberty, the thymus tecreases in size; this process is called involution. 61. The spleen's two functions are defense of foreign microorganisms and provision of a blood 62. Almost all of the interstitial fluid filtered out by the capillaries enters the lymphatic system. 63. A large amount of interstitial fluid that collects in the tissue and causes swelling is called edema. 64. When interstitial fluid enters a lymph vessel, it is called lymph 65. Interstitial fluid fills the spaces between the cells 66. The cisterna chyli is in the thoracic cavity just inferior to the left subclavian vein. 67. The tunica media of lymph vessels is similar to that of veins except the lymph vessels have no reservoir smooth muscle The semilunar valves of the lymph vessels are formed from folds of the tunica intima The "beaded" appearance of lymph vessels is caused by bands of smooth muscle tissue 68. 69. surrounding the vessel. 70. The high degree of permeability of lymphatic capillaries allows particulate matter to enter the capillary. 71. Blood in veins and lymph in lymph vessels are moved by the same kinds of pumps." 72. Even though the lymphatic system has no single muscular pump like the heart, lymph flows at about the same speed as blood. The lymphatic system returns about 3 liters of lymph back to the blood each day by consistently returning about 125 ml per hour 73. 74. There are between 10 to 15 axillary lymph nodes. 75. One function of the lymph node is to slow down the flow of lymph so that microorganisms and particulate matter can be phagocytized.
