occur in clusters 57. Even though some lymph nodes occur as single nodes, mos 58. Removal of the spleen will most likely render a patient ill for the rest of his or her life. 59, More than 85% of the lymph frorn the breast enters lymph nodes at the lateral edge of the sternum. 60. After puberty, the thymus decreases in size; this process is called involution 61. The spleen's two functions are defense of foreign microorganisms and provision of a blood reservoir 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 smooth muscle 68. The semilunar valves o the lymph vessels are formed from folds of the tunica intima. 69. The "beaded appearance of lymph vessels is caused by bands of smooth musele tissue surrounding the vessel. 70. The high degree of permeability of lymphatic capillaries allows particulate matter to enter the 71. Blood in veins and lymph in lymph vessels are moved by the same kinds of "pumps." capillary. -72. Even though the lymphatic system has no single muscular pump like the heart, lymph flows at about the same speed as blood. 73. The lymphatic system returns about 3 liters of lymph back to the blood cach day by consistently returning about 125 ml per hour. There are between 10 to 15 axillary lymph nodes. One function of the lymph node is to slow down the flow of lymph so that microorganisms and 74. 75. particulate matter can be phagocytized.Explanation / Answer
Chegg’s policy states that we have to attempt the first four parts of a given question
57. True
Lymph nodes mostly occur in clusters.
58. False
While spleen is required in order to destroy worn-out cells of the body especially blood cells, its removal will not make the person ill for the rest of their lives.
59. False
More than 85% of the lymph from the breast will enter the lymph nodes in the axillary region and the rest go into the sternum.
60. True
The process of involution causes the action of a decrease in the size of thymus after puberty.
