The lymphatic tissues/organs illustrated below contain which of the following types of cells?1. reticular cells2. macrophages3. B lymphocytes4. T lymphocytesChoose from the following:(A) 1, 2 and 3(B) 1, 2, and 4(C) 2, 3, and 4(D) 1, 3, and 4(E) 1, 2, 3, and 4 **Histology of the Small Intestine**This image depicts a histological section of the small intestine, stained to highlight cellular structures. The purple stain contrasts various tissue components, providing insight into the intestine's anatomy. ### Key Features:1. **Villi**: The finger-like projections seen at the top of the image are villi. These structures increase the surface area for absorption and are essential for efficient nutrient uptake.2. **Crypts of Lieberkühn**: Located at the base of the villi, these glandular structures are visible as invaginations. They contain cells responsible for secreting intestinal juices and generating new epithelial cells.3. **Muscularis Mucosae**: Below the crypts, a thin layer of muscle can be observed, which is part of the muscularis mucosae. This layer aids in the movement of the mucosa.4. **Submucosa**: The dense layer beneath the mucosa includes connective tissue, blood vessels, and nerves, providing structural support and nourishment to the mucosa above.5. **Peyer's Patches (highlighted by larger rectangle)**: These appear as circular or oval darker regions in the submucosa, representing aggregations of lymphoid tissue. They play a role in the immune surveillance of intestinal contents.### Explanation of Diagrams:The image contains two highlighted boxes. - The **larger rectangle** centers on a villus, crypts, and part of the underlying submucosa, indicating the transition between epithelial structures and lymphoid tissues (Peyer's patches).- The **smaller rectangle** focuses specifically on a segment of the submucosa, likely emphasizing histological details such as cellular makeup or tissue arrangement.This tissue architecture supports the primary functions of the small intestine: nutrient absorption, digestion, and immune response.

Introduction:- The immune system is a complex system comprising of a meshwork of lymphatic organs, tissue, cells. The organs and tissue involved in lymphatic system can be categorised as: Primary lymphatic organs Secondary lymphatic organs The red bone marrow and the thymus form the primary lymphatic organs. and secondary lymphatic organs play a significant role in the immune system because these form the sites where lymphocytes reach and bind with antigen.The lymphatic tissues/organs illustrated below contain macrophages,B lymphocytes,T lymphocytes types of cells. Hence, Option c is correct. The lymphocyte cells that circulate in your blood are part of the immune system. There are two main types of lymphocytes: T cells and B cells . B cells produce immune cells that can capture and destroy invading bacteria or viruses. Several types of cells are embedded in the lymphoid system -for example , white blood cells such as macrophages and lymphocyte .
