A ring of lymphoid tissue that appears as a swelling of the mucosa in the oral cavity is called a(n). Tonsil. Explain why the lymphatic system is a one-way system, whereas the blood vascular system is a two-way system. Blood vessels form a complete circuit from and to the heart.edulla. Lymph enters the subcapular sinus of the lymph node through the ________. Afferent lymphatic vessels. As lymph exits the hilum there are fewer of these types of vessels draining the node than feeding it.
Mucosa-associated lymphoid tissue (MALT) is found in various parts of the body, but the predominant site with the highest volume of this tissue is the gastrointestinal tract. It plays an important role in immune surveillance, mucosal regeneration and is also involved in carcinogenesis [1].
