- It sometimes is difficult to distinguish the different lymphoid organs from one another in histological sections. How would you tell the thymus from a lymph node? (a) Only the thymus has a cortex and medulla; (b) lymphocytes are far less densely packed in the thymus than in the lymph node; (c) the thymus contains no blood vessels; (d) only the thymus has distinct lobules and thymic corpuscles.1. (a)Where would you expect to find most of the plasma cells in a lymph node? (b)And What kinds of cells are in the cords of the Red Pulp?Which of the following lymphoid organs have a cortex and a medulla? (More than one choice is correct.) (a) lymph nodes, (b) spleen, (c) thymus, (d) aggregated lymphoid nodules, (e) tonsils.
- Compare and contrast the morphology of the tissue slides of tonsils and the infant thymus.(i) Describe 2 ways that they are similar in structure and 2 ways that they are different in structure? (ii) On what morphological feature would you determine that tonsils are secondary lymphoid organs?Which of the following is the only lymphatic organ to demonstrate AFFERENT lymphatic vessels? Choose from the follliwng: (A) tonsil (B) spleen (C) thymus (D) lymph nodeThe basic structural framework of most lymphoid organs consists of (a) areolar connective tissue, (b) hematopoietic tissue, (c) reticular connective tissue, (d) adipose tissue.
- Which one of the following lymphoid organs does not contain lymphoid follicles or germinal centers? (a) lymph nodes, (b) spleen, (c) thymus, (d) aggregated lymphoid nodules, (e) tonsils.The tributaries of the common iliac vein would be: Rt. And Lt. internal iliac veins Rt. And Lt. external iliac veins Internal and external iliac veins Rt. And Lt. femoral veinsLymphocytes that develop immunocompetence in the thymus are (a) B lymphocytes, (b) T lymphocytes.
- Describe the basic structure and cellular population of lymphoid tissue. Differentiate between diffuse and follicular lymphoid tissuesDue to the presence of breast cancer, Mrs. Franco had a right radical mastectomy in which her right breast, underlying muscle, and right axillary lymph nodes and vessels were removed. Now she is experiencing severe swelling in her right arm. Why did the surgeon remove lymph tissue as well as the breast? Why is Mrs. Franco’s right arm swollen?Identify the two categories of lymphoid organs and their roles in the body's immune response.
